Post, Mark The design and application of inducers is not widely understood outside the turbomachinery design community. Inducers are not a panacea for all low Net Positive Suction Head challenges, but they serve a valuable purpose when properly applied. The goal of this workshop is to provide an overview of Net Positive Suction Head (NPSH)…

Schreier, Gerd Piping systems experience occasionally unexpected vibrations. The responsible operations/maintenance engineer needs to able to determine if corrective actions need to be implemented. If changes on the piping system are imperative, he further needs to understand the source of the vibration in order to select the correct solution. Resonance effects, which are in most…

Ramirez Mata, Agustin Centrifugal pumps utilized in heaviest duty environments are usually prescribed as API 610/ISO 13709. Since the first edition of their standard released in early 50’s last century, we are now reaching its 12th edition. The way to choose the pumps types is giving the possibility to have long life cycles, with maximum…

Fischer, Jan The presentation starts with a definition of the pressure ranges when talking about Vacuum Pumps and Compressors. A description of the working principle and the resulting details and limits when operating liquid ring machines follows. Especially the function and different ways to guide the service liquid flow are explained. In the second part…

Rodríguez Fernández, Ángel Most of the thermal power plants are cooled with water. This water can be interchanged between a condenser and the sea, a river, a lake, a cooling tower, etc. But always there must be pipes that connect the steam turbine condenser with the place where the water is cooled. There are some…

Baron, Herve Large complex projects entail a high number of highly inter-related activities. One must be able to stand back, identify the priorities and attend to them. Even though each project has unique features there are repeating patterns. The critical path and show stoppers are always the same, in particular Information from Equipment vendors and…

Bittorf, Frank In order to allow thermal movement of a piping system and save the piping system from unplanned movements, different types of flexible pipe supports and safety elements are needed, mainly Constant supports, variable supports as well as rigid struts and shock absorbers. This seminar will explain in detail the different working principles, technical…

Graziano, Vimercati In recent Oil & Gas mega projects we experienced increasing requests for centrifugal fans operating in severe duty conditions with constraints related to limited installation areas, being the plant layouts already decided and frozen at project early stage. Therefore, the selection of the most adequate rotating machine became more and more sensitive in…
