Bellows: For the transmission of high temperature liquid and gas. Such as water heater intake pipe, gas transmission pipe, tap intake pipe, etc. For areas with poor water quality, the connection pipe of water heater can be preferred to corrugated pipe, and the service time is longer. The advantages of stainless steel bellows are corrosion resistance, high temperature resistance and high pressure resistance. A large diameter equals a large flow of water. The disadvantage of stainless steel bellows is that they must be installed in a vertical state with the joints, which can easily lead to leakage. Bellows are not easy to bend at the same place for many times, otherwise the wall of the bellows will be broken. A: Components of different stainless steel hoses: wire, inner pipe, steel sleeve, core, gasket, nut bellows: hexagonal cap, pipe body, gasket, plastic sleeve B: different functions of braided pipe: mainly to play the role of water intake corner valve and basin faucet, kitchen faucet, vertical bathtub faucet, water heater, central air-conditioner, toilet seat, forming water supply channels or drainage pipes.

C: Stainless steel braided hoses with different fabrication methods and performances: 6 strands of 304 stainless steel wire are used to make the hoses. The whole hose has better flexibility and anti* effect, but compared with bellows, the diameter is smaller and the water flow is smaller. Stainless steel bellows: the tube body is uneven, only one outer tube, no inner tube, the tube body is hard, special attention should be paid to the installation, it is best to choose vertical installation, must not bend in the same place many times, in order to avoid leakage and fracture.
