Water Hammer Basics: Water hammer, also known as hydraulic shock, is a term for the destructive pressure surge and accompanying shock wave that takes place in piping systems when the rate of flow changes suddenly. That shift causes a large vapor pocket to form within the pipeline; when the pocket collapses, a powerful, bidirectional pressure

Video: How To set Shell and Nozzle Parameters in Nozzle FEM
Nozzle-FEM is designed for stresses and flexibility calculation of nozzle-to-shell junctions using the Finite Element Method (FEM). The program also calculates nozzle’s allowable loads and estimates strength of the nozzle’s junctions for wide range of geometric configurations and operating conditions. Nozzle-FEM helps to provide higher level of the equipment safety along with reducing labour costs
