Flanges, Lap Joint Type

Haji Iron & Steel Works offers Lap Joint Flanges, which are practically identical to a slip-on flange except it has a larger radius at the intesections of the bore and flange face. It is used with their associated stub end. The stub end is welded to the pipe and the lap joint then works as a backjing ring. The advantage of this flange is that the bolt holes can be aligned with the matching flange after the weld have been completed. This flange is not suitable for areas with thigh external or dynamic loads.
