Lap Joint flange is a movable flange piece, which is generally matched on water supply and drainage accessories. When the manufacturer leaves the factory, there is a flange at both ends of the expansion joint, which is directly connected with the pipeline and equipment in the project with bolts.
Lap Joint flange is to save materials. Its structure is divided into two parts. One end of the pipe is connected with the pipe and the other end is made into butt welding ring. The flange plate is made of low-grade materials, while the pipe part is made of the same materials as the pipe, so as to save materials.
