[10:00 – Room A] — Fundamentals of valve selection

G. Malinverno

Valves are the components in a fluid or pressure system which regulate either the flow or the pressure of the fluid”: this description highlights the main role played by valve in a system. Beside other considerations, thus, the first point in the valve selection workflow is to define why we need a valve in our system, i.e. to control the pressure inside a vessel, to regulate the flowrate, eventually in a dynamic way, or only stop or allow the flow. While the latter function can be performed by practically all types of valve, pressure control and flow control require the use of engineered valves, to obtain tailored solution and avoid waste of energy, money, and unwanted consequences like erosion or vibrations. Once defined the valve function, the following points shall be duly considered: • How the valve will be operated, i.e. manually or with a dedicated operator (e.g. hydraulic electric actuator). • The leakage allowed, within the system and towards the environment. • Process fluid properties, e.g. type of fluid (clean, slurry), thermophysical process data (pressure, temperature), etc. • Boundary conditions, e.g. where the valve will be installed (environmental conditions) and how the valve will be connected to the pipeline / vessel. • Additional constraints like project specifications and applicable codes. Please note that all these points interact with each other and, virtually, they shall be considered simultaneously. Indeed, an iterative design approach can be used – a good starting point could be the latter since codes or specification already define the type of valves are allowed or, at least, limit the range of possibilities. Some examples of real applications will be carried out, especially considering specified design codes like API and ASME and different requirements like the flow coefficient and the minimum flow. Additionally, main issues like cavitation, erosion, chattering, and jamming will be briefly discussed.

J. Macías

Digital Transformation, Digital Twins, Industry 4.0, and Cloud computing are buzzwords that arrive later in the Industry and in particular in Oil Refining but really, what is really new? and what are the lessons learned from that? In this presentation, we are trying to answer some of these questions from a professional perspective.

[10:00 – Room D] — Integrity assessment of equipment containing identified flaws or damage (CADE)

Berenguel Herraiz

When a specific flaw or damage (deformations, corrosion, cracks, local/ general metal loss, etc) appears in existing equipment and piping systems, the immediate step is to analyze the serviceability to guarantee an acceptable level of safety and accurately determine its remaining life as well. The analysis of the suitability of an equipment to continue in service is carried out by performing a fitness for service (FFS) assessment. The API 579-1-ASME FFS-1 standard establishes three levels of Fitness for Service analysis. These three levels are progressive and the choice of one or the other will depend on the level of detail required. The acceptance criteria of levels 1 and 2 are much more conservative than those corresponding to level 3 because this level 3 is based on numerical methods such as finite elements that involve much more complex analysis. The advantages of performing structural analysis using finite elements are widely known, since it allows the determination of the stress states of damaged equipment with great precision, therefore, the acceptance criteria established by the API 579-1-ASME FFS-1 standard for a level 3 are more precise, which offers advantages from an economic point of view. However, after the detection of certain defects that cast doubt on the capacity of the equipment to continue on service, another question that arises is what has been the origin of these deformations. The answer to this question can be provided by performing a RCA analysis (Root Cause Analysis).

[10:00 – Room F] — Hygienic grade piping

E. Legname

Biohazard, Hospital, Pharma and Hygienic grade Piping use Industry standards in Europe differ widely for the use of Food processing, Pharmaceutical plants, or Health Care facilities. Preparation of specifications are therefore specific to life sciences and follow hygienic codes that in cases have experienced large amount of addendums in recent times for both American and European standards. Piping, Process and Mechanical expertise with Pharmaceutical background can be then specific but enriching designs with engineers developed within the Energy and Chemical sectors can prove to be a gap difficult to close. Follow us in our PEW2023, where we review and debate about the challenges facing the design of Hygienic grade systems.

[10:00 – Room G] — Compressor selection for green Hydrogen (TR)

J. Saceda

[10:20 – Room B] — H2 and O2 piping systems

E. Legname

Hydrogen & Oxygen production. Piping considerations. The Climate Change has emerged as an industry point of inflection for the production of Clean Energies. Among these, the production of Oxygen and Hydrogen are bi-products of Electrolysis, being this a Green Hydrogen source. Handling of Hydrogen however requires many considerations only recently seen in ASME code. For Oxygen the challenges are even greater due to its great flammability. EIGA standards and impurities play a very special paper within this scenario. Follow us in our PEW2023, where we will review and debate about challenges posed for the design of Hydrogen and Oxygen networks.

[10:20 – Room C] — Functional safety analysis methodology for industrial plants

G. Malinverno

Functional safety is the part of the overall safety of a system or piece of equipment that depends on automatic protection operating correctly in response to its inputs or failure in a predictable manner (fail-safe)”. Being related to the architecture of the industrial plant and to the required safety function, different approaches can be adopted to define and later assess the safety instrumented system. The definition of the safety requirements is determined by methods such as HAZOP (HAZard and OPerability) and/or LOPA (Layers Of Protection Analsyis), as indicated by applicable standards (IEC 61508 and 61511). SIS design, construction, installation, and operation shall be duly assessed to verify that these requirements are met, through different approaches like FMEDA, factory and site acceptance tests for example. One of the key quantities to be assessed is the probability of failure on demand (PFDavg) and its verification is the core carried by reliability analysis. The classical approach based on the “Failure Modes, Effects, and Criticality Analysis” will be briefly discussed to highlight its simplicity and how to implement it in a semi-automated workflow, eventually with in-house solution. However, even if the FMECA is an excellent hazard analysis and risk assessment tool, it has some shortcomings that shall be carefully considered. For example, it does not deeply consider combined failures or interactions, especially when the system cannot be easily reduced in a sequence of reliability block in series or parallel. Additional tools shall therefore be taken in account, an example is the reverse fault tree analysis, eventually in association with advanced mathematical tools like the Monte Carlo simulations through the Bayes Belief Network. The combination of fault tree analysis and Monte Carlo simulation shows its advantages over the FMECA since it is helpful not only in the final stage of reliability assessment but also in a design phase or when different maintenance scenarios shall be compared.

[10:20 – Room D] — New Concepts of Biorefinery from Waste-to-Fuel (Sacyr – Fluor )

J. Sánchez Fontao

The European Green Deal for the European Union (EU) entails a new growth strategy to transform our society and economy into more competitive and resource-efficient, achieving the target of zero net emissions of greenhouse gases by 2050. Key measures of the European Green Deal integrate a zero-pollution ambition, having an available and secure clean energy, and the sustainable industry. In this context, the circular economy determines an action plan to cover the lifecycle from production to waste management. The Energy and Process industries are transforming their traditional linear business models into circular economies, producing feedstocks from waste as raw material. This will also contribute to meet new targets for waste disposal that are currently implemented in the EU. Specific types of waste can follow different technological routes to produce fuels that define new concepts of biorefineries. • The lipidic route where used cooking oils from food industry is transformed into renewable diesel by hydrogenation. • The biological route where organic matter from municipal waste and agriculture industry is transformed into biogas, biomethane by anaerobic digestion. • The thermochemical route where mixed residual waste and biomass is transformed into syngas and synthetic oil for refining by gasification or pyrolysis. These concepts will be introduced as part of the presentation seminar given in the PEW23 organized by InIPED at the University of Zaragoza.

[10:40 – Room B] — New technologies for design and assessment

G. Malinverno

Traditional methods of design and product validation, like analytical calculations and numerical simulations based on finite volumes or elements, have been joined by a series of tools based on various new technologies, both at level of abstract methodologies and electronic hardware. Examples of these tools can be found in data science and machine learning, where the amount of available data are used to develop predictive modes for various applications, like reliability of complex systems as well as hydrodynamics studies. Indeed, mathematical techniques indicated in previous sentence can be also applied to new hardware, namely quantum computers but also extension of traditional HPC solution, that could extent the potentiality of such mathematical tools. The presentation will provide a summary of potential tools that can be useful used in industrial application with already consolidated examples as well as future possible solutions.

Different examples of such functionality are demonstrated for PASS analysis software and different 3D CAD systems.

[11:30 – Room B] — Centrifugal Compressors: A basic Overview from design to operation

A. Belhadj

Centrifugal compressors are used in many different processes in oil and gas industry due to the advantages they offer (compact structure, high pressure ratio, good reliability and wide operating range). Designing a centrifugal compressor in a way to meet the required technical specifications predefined by the customers is a challenging phase for manufacturers who pass through a relevant design step before proceeding to manufacturing than factory testing. Based on its application, centrifugal compressors are supposed to operate safely, correctly and efficiently for the desired working lifetime by ensuring good quality commissioning activities after installation, a healthy startup and good maintenance follow-up. In this workshop, we will present a basic overview on centrifugal compressors life cycle from design to operation.

[11:30 – Room C] — Decommissioning of Offshore Oil and Gas Installations (Repsol)

S. Villacampa

Any mining asset has life cycle, it has a beginning and further development, but a end too. A correct planning of their late life phase including a bundle of activities related with the decommissioning phase will be crucial to ensure, that the installation will be correctly dismantled in a safe way. Hundred of installations around the world will enter on their late life phase during the following years. Not all the installations were designed to be “friendly” dismantle. All these circumstances will challenge to the operations and project team to develop a correct plan. This speech is intended to provide a slighltly view from a Decom project on the way, offering a new world that will provide employment in the next years.

[11:30 – Room E] — Real gas thermodynamics in compressor system applications (Neuman Esser)

E. Steinbusch

Thermodynamic models are used for the calculation of vapour-liquid equilibrium and thermophysical properties of a single component fluid as well as multicomponent fluid mixtures. Many different thermodynamic models were developed and are available. The use of a wrong model can lead to inaccurate or even completely useless results for the overall process simulation. Although the presented thermodynamic models based on virial and cubic equations of state, were published in the 1970s, they are still nowadays widely used. Their advantages are simplicity of application, only a few input parameters need to be determined and low computational time. The NEUMAN & ESSER tool KO³, to design and calculate compressor systems, uses the Lee-Kesler, Redlich-Kwong-Soave and Peng-Robinson equation of state to calculate the real gas thermodynamics in compressor applications. The presentation gives you a brief introduction into the applied models and shows simulation results in form of thermodynamic state diagrams. The calculation of reliable thermodynamic state diagrams of fluid mixtures provides guidelines for optimization of the whole compressor system process.

Main topics: Introduction to Hydrogen. Types of hydrogen considering the source of production. Hydrogen Pipeline transportation. Hydrogen in existing process plants, feedback and lesson learns.

[11:30 – Room G] — Steady state and transient calculations of hydrogen piping systems with AFT software (Catalonia Engineering)

J. Garcia

AFT software can help design and calculate hydrogen piping systems in steady state but also during transients. One transient application is the fill process of a high-pressure tanks in cars. The filling process must be reasonably short but must be designed to avoid too high temperatures in the tank. The shorter the filling time, the higher the temperature inside the tank. The software AFT xStream can help in the simulation of the filling process and an example will be presented.

[11:50 – Room B] — Upscaling biogas plants

M. Miana

Biogas is obtained from anaerobic digestion of solid wastes or wastewaters. It is mainly composed of methane, carbon dioxide and water. Current production of biogas in Europe is 3 bcm, and it is expected to increase up this value up to 35 bcm in 2030, covering 10 % of the total EU gas demand. In the end of 2018, Europe comprised 18202 biogas plants, but most of them are in the size range of 100 – 500 kW of electrical output. ITAINNOVA has experience to scale up different biogas plants to increase their power production for larger market penetration. The first upscaling example is the analysis of an aerobic reactor for wastewater treatment under LIFE Multi-AD project. Starting from a laboratory plant of 100 l of capacity, Digital Twins from Computational Fluid Dynamics simulations are developed for the design a real plant of 100 m3, which is now successfully operating. The second example is the recommendations performed over the plant of 1 tn/day of solid biowaste built by the ValueWaste EU project. The integration of the different processes and the solution of mass and energy balances in the current plant have revealed the potential of hybrid solar panels as the best way to improve the economic balance of future larger plants. These projects have received funding from the LIFE Programme of the European Union under agreement number LIFE17 ENV/ES/331 – LIFE MultiAD 4 AgroSMEs and from European Union’s Horizon 2020 Research and Innovation Programme under Grant Agreement No. 818312.

R. Ramirez

Pipes, valves, foundations and skids are static equipments and so are designed. But…what happens when vibration phenomena appear. Their lifecycle is reduced, and their reliability is affected, thus generating great inconveniences in the industry processes. In this conference main causes of the vibrations will be presented, their consequences and how to solve them.

[11:50 – Room D] — ASME PCC-2: Repair of Pressure Equipment and Piping (Arveng Group)

J. Tirenti

Due to the actual international context, the various crises experienced recently and the obsolescence of many industrial plants, certain sectors are going through a critical situation with serious operational, maintenance and growth deficiencies. Now more than ever, adequate knowledge and application of mechanical equipment repair techniques is essential. Advances in technologies for in situ repair of pressurized equipment has created the possibility that the anticipated service life of equipment repairs may equal or exceed the expected life of the repaired components. ASME PCC-2 provides methods for repair of equipment, piping, pipelines and associated ancillary equipment within the scope of ASME Pressure Technology Codes and Standards after it has been placed in service. These repair methods include relevant design, fabrication, examination, and testing practices and may be temporary or permanent, depending on the circumstances. The methods provided in this Standard address the repair of components when repair is deemed necessary based on appropriate inspection and flaw assessment. ASME PCC-2 guideline does not differentiate between permanent and temporary repairs, leaving the Owner to assess the associated risk of continuing service.

[11:50 – Room E] — Basics of plant design with KO3 (Neuman Esser)

P. Atrops

NEUMAN & ESSER inhouse software tool for compressor design and calculation “KO³” has been extended by transforming the compressor calculation in a plant system calculation. The cylinders of piston, diaphragm or hydraulic driven compressors can be connected through pipes with other plant equipment components like pulsation vessels, heat exchangers and separators in a grid-based one-dimensional configurator. Standardized configurations can also be created immediately and extensions in the plant system can be made comfortably. The plant equipment components must be defined in terms of geometry and performance. This data can also be estimated by NEUMAN & ESSER internal standards and design rules for piping, pulsation vessels and heat exchangers. Boundary conditions at the system inlet and outlet must be defined to calculate the plant system. If bypass lines or other stepless control devices on the compressor cylinders are available, the boundaries can be extended to interstage pressures, temperatures, or mass flows. The solution of the plant system is calculated using the Newton’s method. To understand the power of this new calculation approach, an example of a re-liquefaction process of a boil off gas is shown. The process is also visualized in pressure-enthalpy diagrams which can be directly provided by KO³.

[11:50 – Room F] — The internet of things ( IoT ) in the oil & gas industry : two examples of sensors for real-time data collection (Signos)

J. Lausín

The new digital environment is driving the oil and gas (O&G) industry to become more innovative and deploy smart field technologies, to increase operational and asset efficiency, minimize health, safety, and environmental (HSE) risks, improve asset portfolio, reduce capital and operation costs, and maximize capital productivity. The Internet of Things (IoT) is at the forefront of this digital transformation, enabling seamless real-time data collection, processing, and analysis from a range of equipment, processes, and operations to achieve these objectives. There are various operations/applications in the upstream, midstream, and downstream sectors (e.g., condition-based monitoring and location tracking) for which IoT-enabled solutions have a significant impact and offer a range of opportunities to increase socioeconomic benefits. Two examples of solutions for the O&G industry : 1.- SIMETER OCR. The OCR solution for real-time collection of 99% of manometer gauges , dial level and filling indicators, as well as water meters and gas meters, 2.- SIVALVE . The Ultrasound sensors that allows you to identify the fully closed, fully opened or half way position of any installed manual valve.

[11:50 – Room G] — Testing facility for the investigation of the impact of hydrogen on materials and equipment of the natural gas grid (Aragon Hydrogen Foundation)

V. Gil

Renewable hydrogen will be key to replace natural gas, coal and oil in hard-to-decarbonise industries and transport. REPowerEU has set a target of 10 Mt of domestic renewable hydrogen production and 10 Mt of renewable hydrogen imports by 2030.1 The existing gas infrastructure could be a way of transporting hydrogen between production point and final use. This is precisely the main goal of the HIGGS project “Hydrogen in Gas Grids: A systematic validation approach at various admixtures levels into high-pressure grids” (Clean Hydrogen Partnership, H2020, GA No. 875091). HIGGS’ main objective addresses the potential of hydrogen injection into the transmission high pressure natural gas grid, as way to decarbonise the gas system and gas uses, and one of its most important tasks is the design and development of a R&D platform for the experimental validation of components of grid. This facility will help to perform experiments with actual materials and equipment present in the transmission gas grid to check their readiness for the transport of hydrogen in the near future. The R&D platform consists in an admixture system, a testing platform and a gas separation prototype. The testing platform allocates representative components that can be found in the transmission grid, as well as pipes of different API 5L steel grades. It considers two different sections: i) A static section, where leakages and hydrogen permeance is tested in components (valves of different nature) and connections (threaded joints, flanges, etc.) and ii) a dynamic section, where materials and components failure/degradation is investigated. In all cases the setup is pressurized up to 80 bar, a pressure level present in transmission gas grids. During the experimental campaign, various hydrogen/natural gas admixtures will be investigated. The testing campaign consists in exposing the testing material to the hydrogen blend at high pressure for several months. So far H2/NG blends with up to 20 mol% H2 have been studied and the effect of hydrogen on the steels and main elements of the equipment has been checked at the laboratory after dissembling them from the platform. Finally, to meet cases where users cannot accommodate the presence of hydrogen, test separation systems have been studied. In this regard, membrane technology has been tested for hydrogen recovery from H2/CH4 mixtures with a hydrogen content ? 20% and at a pressure of 40-80 bar, using a Pd-based membrane prototype installed in the R&D platform.

E. Legname

Fuel distribution. Bio-fuel conversion. Rings. Infrastructures. Laboratories. Test New Fuel Farms, Forecourts and Fuel Distribution Systems to be installed in present days and near future to deal with High blended alcohols may require existing fuel tanks and waste tanks servicing current forecourt areas, as well as collective fuel Tanks and associated piping sub-systems to be revisited. With most tank farms exceeding their in-service life cycle, most will need to be replaced to comply with the new safety and technology requirements. Since HBEF fuel distribution network systems to be able to meet the demand of fuel rings, and size manifolds, tank farm and forecourt areas need to be adopted for the future expansion of current standard Fuels or LBEF, a complex study needs to be developed on-plot and off plot to comply with current and future regulations. The challenge also includes the disposal of contaminated oily streams as well as difficulties mixing some biofuels, as well as delivering HBEF, which very nature is still not fully understood nor standardized due to SSC and highly flammable gases needing to coexist within densely populated or operated zones; the design and commissioning of these systems are usually difficult. Follow us in our PEW2023, where we review and debate about the challenges to design Biofuels piping systems.

[12:10 – Room B] — Witness testing and alternative certification scheme for ATEX-certified products (Zalux)

E. Bartissol

In the context of the protection of potentially explosive atmospheres installations, common-ly referred to as ATEX, electrical equipment intended for use in such classified areas must meet the essential safety requirements defined in the applicable legal framework. The assessment of compliance with these requirements is carried out by notified laborato-ries, ExTL, which test and review type samples representative of the series. Such requirements increase the product development, adding additional time for equipment certification, normally 6-8 months. Such situation can lead to delays in the commercial launch of products, which can have a negative impact on the development of the market share. However, for category 2 equipment with a high level of protection, the directive 2014/34/UE (ATEX) and the IECEx system define for other certification schemes which, although more complex, make it possible to reduce certification delays and improve the manufacturer’s con-trol over the process. In the case of electrical equipment manufacturers, if they can demonstrate that the profes-sional capabilities of their technicians, processes, facilities and measuring equipment ensure reliability in measuring the performance of the products they test, the witness testing scheme allows them to perform part of the assessment in agreement with the notified la-boratory in charge of safety assessment. In 2022 the ZALUX laboratory successfully initiated and carried out this process with INERIS, which now allows us to better assess the safety of our products, and to reduce development times by including part of the certification process from the beginning of the product devel-opment phase.

The world is facing an energy revolution, driven by a strong decarbonization push of the economy. Hydrogen is becoming a key player in a decarbonized future. Hydrogen can be produced with abundant sun, wind and water, and can fulfil all of our energy needs. A world of opportunities is rising… But there are significant challenges that need to be overcome before hydrogen can play the role it is expected to play in the future energy systems. In this session we will review all the challenges (from technology to government policies and geopolitics) and opportunities (long term energy storage, P2X, re-electrification, …) affecting the upcoming hydrogen economy.

[12:10 – Room D] — Material Selection for Special Services (Arveng Group)

J. Tirenti

In the processes that are carried out in both, refineries and in chemical plants, there are a multitude of different reactions that are necessary to achieve the proposed objectives. The main objective of these process reactions is to obtain a final product free of all types of contaminants and impurities contained in the raw materials and thus comply with the requirements of the corresponding specifications. To this end, the equipment in which such processes are carried out must be constructed of Carbon Steel materials but subject to certain restrictions, limitations and particular conditions required to withstand the failure mechanisms derived from the presence of different corrosive agents and/or operating conditions such as low and high temperature. While material selection is one of the most important factors in moving your project forward — or optimizing an existing process — it is also one of the most complicated and, often, difficult. Product material selection can provide the gateway to solving problems of part performance, process inefficiencies or issues, or a combination of both — which cannot be overcome through design alone. It can also enable the development of entirely new products offering performance attributes not attained by any existing products, or comparable performance at significantly lower cost, or in some instances even significantly higher performance at lower cost.

[12:10 – Room E] — Sealing Solutions for CO2 applications (EagleBurgmann Germany)

N. Necker

Carbon, Capture, Storage and Utilization plays an important role reducing greenhouse gas emissions and reaching net-zero emission targets by 2050. In the CCS process chain, different rotating equipment is used for Capture, Compression, Transportation and Injection of CO2, these are pumps and compressors. Both have demonstrated their capability to operate successfully, transferring vaporized, liquid or supercritical CO2. Considering this duty as technically challenging, thus it is even more difficult for mechanical seals, which are a vital component of any machine. Sealing technology is highly relevant in the initial engineering phases of a new project for environmental safety and reliability of the equipment. For compressors, transferring gaseous CO2, Dry Gas Seals are the state-of-the-art sealing technology. For pumps, dependent on the liquid or mixed phase of the carbon dioxide, wet mechanical seals or Hybrid Dry Gas Seals in combination with specific API682 Piping Plans are used. This presentation will cover the most reliable sealing solutions used successfully in different pump applications dealing with phase changes of CO2 when operating near their critical point. Dry Gas seals with specific seal face materials like diamond materials and innovative seal face topography like 3D-grooves have proven their sealing performance in these critical services.

[13:30 – Room A] — Typical Pipe Support Installation Errors On Site (LISEGA)

F. Bittorf

Are you curious to see what really happens to pipe supports on site? For almost any large project, pipe supports are purchased in a complex process. Project procurement procedures require highest efforts in documentation, from the smallest details of manufacturer´s welding procedures, complete material certificates, detailed information of the applied painting system, up to precisely formulated packing requirements and more. All that is often subject to final customer´s verification and supposed to guarantee the best level of “security” to the project. However, when it comes to real installation or maintenance of the items, we more and more see a significant increase of severe mistakes on-site! LISEGA will briefly show the functionality and task of the different pipe support types and will show a large variety of the most significant and frequent pipe support installations errors. We will give guidance how to prevent these mistakes, which can have severe, cost intense and sometimes even fatal consequences! This workshop is therefore interesting for simply anyone who´s getting in contact with pipe support, the piping or its adjacent equipment; procurement, technician, engineer, project manager, etc. Curious in finding out what really happens to pipe supports on site and what improvement options exist?

There are many good practices but also pitfalls when designing a pipe class. This seminar will highlight a few common issues and differences between calculation codes such as the ASME B31.3 and the EN 13480-3.

[15:00 – Room A] — CAEPIPE 3D+, the Most Disruptive Pipe Stress Software! (SSTUSA)

P.B. Karthick

It is common practice globally that piping designers route pipes in 3D plant design systems with consideration given mainly to space constraints, process and flow constraints (such as pressure drop) and other requirements arising from constructability, operability and reparability. Most often, while routing piping systems, pipe stress requirements are not given sufficient consideration. A pipe stress software package that meets the following needs would be ideal for use by both 3D piping designers and pipe stress engineers. • Creates pipe stress models directly from 3D plant design systems, • Helps 3D piping designers to perform “first-level” stress checks while routing piping, • Allows 3D piping designers to check for interference of “deformed” piping during “hot” Operating conditions, • Permits 3D piping designers to transfer code-compliant stress models to pipe stress engineers for detailed analysis, • Allows pipe stress engineers to view 3D plant model during analyses to identify (a) locations for pipe supports and (b) available space for any pipe routing changes, and • Permits 3D piping designers to make changes to piping layout and supports recommended by stress engineers by importing finalized stress models into 3D plant design system. SST Systems’ disruptive pipe stress product CAEPIPE 3D+ fulfils the above Needs of 3D piping designers and pipe stress engineers.

[15:00 – Room D] — Flange leak-tightness calculation according to EN 1591-1 (Red-Bag)

R. Botermans

This topic will be about not only the flange strength calculation but especially about the leak-tightness of the flange assembly. An introduction will be given about the flange behavior in combination with the gasket behavior. The gasket properties according EN 13555 like elasticity, compression and creep will be discussed. The participant will get a good idea about the complexity and the importance of the EN 1591-1 calculation.
