Committed for World Class Qualitative LAP Joint Flanges Manufacturing...
JPSPL offers Lap joint pipe flanges in all available material, size and dimensions. Lap Joint flanges slide over the pipe and are utilized with stub end fittings. It is allowed to turn around the stub end and it ensures you that there will not be any issues with bolt hole alignment. It is used in the applications that need frequent dismantling.
ANSI/ASME B16.5 Lap Joint Flanges with the stub end used in piping systems where bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe. These includes in various materials such as stainless steel & high nickel alloy available in number of classes like 150LB, 300LB, 400LB, 600LB, 900LB, 1500LB according to the customer specification.
