Lap Joint Flanges

These lap joint flanges are constantly utilized with either a stub end or taft which is butt welded to the pipe with the flanges loose behind it. This implies the stub end or taft dependably makes the face. The lap joint is favored in low weight applications since it is effectively assembled and adjusted. To lessen cost these stub end lap joint flanges can be supplied without a hub and/or in treated, coated carbon steel.
