→Graphical Introduction Information of Cast iron expansion←

Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd is one of the companies engaged in Cast iron expansion development and marketing. Since Innovation began to provide Cast iron expansion to the market, the company has adhered to the principle of "putting equal emphasis on technology, service and management", , and adhered to high standards for the standardized management of Innovation enterprises. With the strong support of water supply and drainage industry colleagues, Innovation pipeline has continuously increased its technical investment, and the company has gradually developed into a preferred partner for customers in the water supply and drainage field!

    ※Craftsmen cast high-quality products, Innovation Cast iron expansion Product information points:：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.
   water supply and drainage industry Cast iron expansion more application experience can be obtained for free by picking up the phone and immediately consulting Innovation pipeline technicians.
  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.
  Frontier water supply and drainage industry Cast iron expansion product application knowledge can be obtained immediately by calling 0371-68676867 to consult Innovation pipeline technicians.In general, when making a pool, you need to use a sleeve, which is the channel of the pipeline to the pool. 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.
  More useful water supply and drainage industry application new knowledge can be obtained free of charge by telephone consulting Gongyi Zhongyuan Innovation Pipeline Equipment Co., Ltd customer service personnel.
   　　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.
