the characteristics of stainless steel pipe fittings

1. life Forged Steel Socket Pipe Fittings with the longest service life. Stainless steel from abroad usage analysis , the life of stainless steel pipes up to 100 years , there are at least 70 years , as long as the life of the building . 2 , resistance to corrosion Stainless steel pipe is one of the most prominent advantage of its excellent corrosion resistance in a variety of pipe is best . Because stainless steel passivation can occur with the oxidant role in the surface layer of tough dense chromium-rich oxide protective film Dr2O3, effectively preventing further oxidation occurs . While other metal tubing , such as galvanized pipes, copper passivation capacity is very small, which is a brass galvanized pipe corrosion resistance of stainless steel pipe is far less than the key reasons . Stainless steel that will occur as the uniform corrosion , when used without a protective coating ; made ??of stainless steel pipes, chemical composition of the water is not limited , because the oxygen content in a variety of stainless steel , temperature, PH and the hardness of the water are very good corrosion resistance ; stainless steel pipes can withstand a high flow rate , even if the flow rate of greater than 40 m / s, still maintain a very low corrosion rate is not more than 0.003 mm / year, especially for high-rise water . 3, heat and thermal insulation Stainless steel pipe of the thermal conductivity of copper 1/25 , ordinary steel 1/ 4 , particularly suitable for conveying hot water . Water industry is the most commonly used stainless steel 304 and 316 stainless steel , they are able to meet the conditions of the vast majority of water treatment and losers off . 4 , the intensity Determines the strength of the material is sturdy pipes crashworthiness , safe and reliable. The safety and reliability is the most important building in the feed water requirements. Impact force in the case of stainless steel pipes leaking unlikely. Rise water supply system working pressure is generally greater than 0.6Mpa; require a higher pressure on the pipe . Because Thick Wall Square Steel Tube excellent mechanical properties, can withstand high water pressure of up to 10Mpa or more, especially for high-rise water .
