Pressure Vessel Equipment Design - By The - Engineering

Shape of a Pressure Vessel.Pressure vessels can theoretically be almost any shape,but shapes made of sections of spheres,cylinders,and cones are usually employed.A common design is a cylinder with end caps called heads.Head shapes are frequently either hemispherical or dished (torispherical).PolyLock Attaches HDPE Geomembranes in Storage TanksThe embedment of anchor fingers provides a high-strength mechanical anchor to the concrete.When properly installed and utilized with a geomembrane,GSE PolyLock provides an outstanding barrier to leakage.It is the most effective and economical cast-in-place mechanical anchor system for HDPE.Applications.Storage Tanks,Secondary ContainmentPhysics 2 - UCSBPrepared by Vince Zaccone For Campus Learning Assistance Services at UCSB 14.30 A hollow plastic sphere is held below the surface of a freshwater lake by a cord anchored to the bottom of the lake.The sphere has a volume of 0.65m3 and the tension in the cord is 900N.
