Flanges are used as a connection profile in Pipeline and associated equipment to provide means of assembling and disassembling components. Most flanges in Oil and Gas Industry feature a bolt-hole pattern to allow the joint to be secured and a gasket profile to ensure a pressure tight seal. The design and specification of a flange relates to the size and pressure capacity of the equipment to which it is fitted.
