Cast Steel Bolt Bonnet

Cast Steel Bolt Bonnet :The body flange and bonnet flange are joined by studs and nuts,with a gasket of suitable design/material inserted between the flange faces to facilitate sealing.Studs/nuts/bolts are tightened to prescribed torques in a pattern defined by the manufacturer to affect optimal sealing.However,as system pressure increases,the potential for leakage through the body/bonnet joint also increases.
