GGG400 Single Flange Limited Expansion Joint

  Single flange limited expansion joint is applicable for welding with a flange on the one side, with a pipe on the other side. During the installation, adjust the installation length to the pipe and flange on the both sides, screw the bolts firmly one by one, weld the short pipes with the pipe, and then adjust the limited nut. This method makes it possible for the pipe to expand and contrast freely within the allowable range of the expansion joint. It also can secure the safe operation.
