→Graphical Introduction Information of Rigid waterproof casing pipe←

    Craftsman makes craftsmanship, focusing on Innovation Rigid waterproof casing pipe product knowledge points in Municipal engineering pipeline construction field:：The double flange limit expansion joint is composed of body, sealing ring, gland, extension and shortening pipe and other main components. On the basis of the original performance of the loose sleeve expansion joint, a limiting device is added, and double nuts are locked at the maximum expansion capacity. vssja-2(b2f) double flanged limit expansion joint is suitable for connecting both sides with flanges, adjusting the connection length of both ends of the product during installation, tightening the gland bolt evenly in turn, and then adjusting the limit nut, so that the pipe can expand freely, lock the expansion amount, and ensure the safe operation of the pipe.
  More Municipal engineering pipeline construction industry application new knowledge can be obtained free of charge by telephone consulting （ water supply and drainage equipmenttrusted product partner）Innovation pipelineChina Innovation pipeline International Marketing Department customer service personnel.Rigid waterproof casing pipe is suitable for structures (buildings) that do not withstand pipeline vibration and expansion deformation at the point where the pipeline passes through the wall. For areas requiring earthquake fortification, such as rigid waterproof casing pipe, flexible connections should be set near the pipeline entering the pool wall or the external wall of the building. Type A is suitable for steel pipes.
