Read MoreMechanical Seals and Supply Systems in accordance with API 682 4th Ed, critical pump applications
Bagues, Fernando & Zabala, Lorenzo API 682 is a standard of the American Petroleum Institute. Several factors play a major role when choosing the mechanical seal for an API 610 pump, the product type, the materials used and how it is operated: process conditions at the sealing location, operating conditions and the medium to be…
Read MoreSelf-reinforced nozzle calculation
Tirenti, Javier In some applications (special services, lethal, cyclic) is recommended to minimize the amount of welds on the pressure vessel, in this sense, the less amount of welded joints the less chance of weld failure. If on top special/lethal services the vessel must be defined for high pressure, it is necessary to design the…
Read MorePV External Pressure Calculation
Tirenti, Javier The failure mechanism of external pressure is different from the failure induced due to internal pressure; therefore, different methods are required to design vessels to handle these two separate conditions safely. External pressure failure the vessel can no longer support its shape and suddenly, irreversibly takes on a new lower volume. In this…
Read MoreSlug Flow. Dynamical approach
Oliver Piay, Karen Slug flow is a phenomenon that occurs under special circumstances of two phase gas – liquid flow. It is the most serious scenario in two phase flow as it involves a moving liquid mass pushed by gases in between. In most of engineering companies the effect of slug flow is considered by…
Read MorePulsation Analysis and steps to improve solutions
Méndez Vilariño, Daniel Every time a positive displacement machine needs to be installed it is necessary to guarantee equipment operation free of pulsation. During this presentation we will analyze minimum requirements and practical solutions for pulsation studies. Also recommendations about when how and where implement them will be presented. Idea is to present a follow…
Read MorePressure balance expansion joints. Theoretical basis and examples of use
Oliver Piay, Karen When the space/ access constrains or the excessive magnitude of the axial thrust imposed by the unbalance area of the bellow, under internal pressure is a main concern in designing the Piping System, the only solution is to use a pressure balance expansion joint. The theoretical basis and example of use of…
Read MoreModal Analysis for the Plant Machinery Engineer. Recipes and Shortcuts. Part II
Vázquez, José Antonio Experimental modal analysis and operating deflection shapes (ODS) are powerful tools in vibration analysis and machinery troubleshooting. However, the plant machinery engineer often doesn’t believe such techniques are available given a lack of advanced measurement equipment. This tutorial presents best practices with simplified experimental modal analysis and ODS techniques that can be…
Read MoreThermosolar power plants: Molten salts pipes design requiremens and supporting considerations.
Rodríguez Fernández, Ángel Some Thermosolar power plants use molten salt in order to be able to produce steam after the sunset or during cloudy days. Some of them heats directly the molten salt with the sun light and other ones heats it using a heat transfer fluid (HTF). Molten salt can be considered as an…
Read MoreIntroduction to piping in EPC Projects
Oliver Piay, Karen A piping system is the most effective and commonly use way of carry fluids in the industry. For example, in a petrochemical industry the piping system represent around 35% of all industry material and requires around 40% the construction and erection man hours and it could require up to 50% of engineering…
