（ water supply and drainage equipmenttrusted product partner）Innovation pipelineChina Innovation pipeline , focusing on the development, supply and sales of Steel expansion series products for many years. . With the strong support of water supply and drainage industry colleagues at home and abroad, Innovation pipeline has continued to increase its investment in technological innovation in Steel expansion, and the enterprise has gradually developed into a preferred partner for water supply and drainage customers!

    ※The correct choice comes from knowledge accumulation. Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd reminds industry friends to understand this:：The single flange limit expansion joint is composed of a loose sleeve expansion joint and a limit short pipe. The single-flange limit expansion joint is used for connecting with the flange on one side and welding with the pipe on the other. During installation, the installation length of the product and the pipe or flange is adjusted. The gland bolt is evenly tightened diagonally, and the limit nut is adjusted, so that the pipe can be freely expanded within the expansion range, locking the expansion amount and safe operation of the pipe.

  02S404 flexible waterproof casing pipe is suitable for the hardware pipe fittings of the structure that is subjected to vibration or strict waterproof requirements where the pipe passes through the wall. If the wall where the flexible waterproof casing pipe passes through the wall, the concrete wall should be used if it is not concrete, and the sleeve must be solidified in the wall at one time. Flexible waterproof casing pipe is widely used in construction, chemical industry, steel, tap water, sewage treatment and other units.

However, ordinary casing is difficult to seal, so there will be water leakage between the casing and the pipe, and it is also easy to leak between the casing and the wall. Only the waterproof sleeve solves the water leakage between the sleeve and the wall, and can not solve the seal between the sleeve and the pipe, and the flexible waterproof casing pipe can solve the two problems.

   　　Casing can be divided into: ordinary casing - 2 to 4 cm thicker than the pipe to be used, fixed in the wall or plate, through which the pipe passes.Flexible casing - that is, between the casing and the pipe with flexible materials to seal the effect. Casing - that is, the steel material between the casing and the pipe is blocked to achieve the sealing effect. Waterproof casing pipe - that is, the environment used by the casing is to prevent liquid leakage or leakage into the place (such as pools, septic tanks, basements, etc.), that is, the outer wall of the casing adds not less than 1 circle of waterproof wings, so that the casing will become a whole when it is poured in the wall, and will not leak due to cracks caused by expansion and contraction factors.
