（ water supply and drainage equipmenttrusted product partner）Innovation pipelineChina Innovation pipeline International Marketing Department has focused on Rigid waterproof casing pipe technology research and development for many years, Grow in challenges and surpass in innovation! Innovation can design and improve products according to Municipal engineering pipeline construction customer requirements. Innovation pipeline series Rigid waterproof casing pipe products, compared with similar products, have strong price advantages, excellent technical content and assured after-sales service, which are highly praised by Municipal engineering pipeline construction customers.

    Easy decisions come from knowledge accumulation. Innovation pipeline reminds friends to understand this:：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.
  Pick up the phone and immediately consult Innovation pipeline technicians to obtain updated Municipal engineering pipeline construction industry Rigid waterproof casing pipe application experience.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.
