Tirenti, Javier To attach a nozzle in a pressure vessel, it is necessary to make a hole in the shell or head body in question. When making this hole, an area of the vessel is being “taken away”, therefore stress paths are going to divert tangentially to the hole. Thus, we must “substitute” the removed…

Metz, Kolja Thermoplastic labyrinth seals offer the possibility to reduce the internal leakage flow over the cover disc of closed impellers in centrifugal compressors. The efficiency gain compared to traditional metallic labyrinth seals mainly depends on differential pressure and sealing clearance. The presentation shows the results of development and testing of thermoplastic labyrinth seals, which…

Teijeiro, Beatriz In the past, most of the Oil&Gas industries used conventional pressure reducing valves to suit to downstream process conditions. Therefore, a big amount of hydraulic energy was dissipated and wasted. Hydraulic Power Recovery Turbines (HPRT) were developed in order to convert this pressure into mechanical shaft energy and increase the overall process efficiency…

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…
