These lap joint flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. The lap joint is favoured in low pressure applications because it is easily assembled and aligned. To reduce cost these stub end lap joint flanges and carbon steel lap joint flanges can be supplied without a hub and/or in treated, coated carbon steel.
