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 .

Stainless steel pipe fittings and installation techniques to identify methods

Stainless steel has a unique resistance to corrosion , which can react with the oxidant to form a thin dense oxide film , for preventing the occurrence of the oxidation reaction into further . For other types of Forged Steel Socket Pipe Fittings , almost no passivation function, which is stainless steel pipe fittings material corrosion resistance than the general one of the main metal pipe . Stainless steel piece is considered healthy material , widely used in food processing pipeline , including the pharmaceutical industry , beverage , brewing and so on. Stainless steel pipe fittings material superior performance, effectively reducing transport costs in the long process of transporting no scaling, smooth wall , while conveying low energy consumption, is by far the lowest-cost water transport material . I. Classification and use stainless steel pipe fittings 1, stainless steel pipe fittings Category Seamless Steel Pipe Fittings belonging to a kind of material it is made of stainless steel pipe fittings made ??of so called , which includes : stainless elbow , stainless tee, stainless steel crosses, stainless steel reducer pipe, stainless steel cap , etc., Socket connection methods can be divided according to type of forged branch outlet fittings , threaded stainless steel pipe fittings , flanges and welded stainless steel pipe fittings stainless steel pipe fittings four categories. Stainless steel elbow pipe fittings used in place of turn ; flange for tube and pipe interconnected parts, connected to the pipe end , stainless steel pipe tee together for three places ; stainless steel tube for four -way pipe pooled place ; stainless steel reducer for two tubes of different diameters coupled place . 2 , the use of stainless steel pipe fittings Stainless steel pipe fittings can use paint or oxidation-resistant metal ( eg , zinc, nickel and chromium ) plating to ensure the steel surface , but, as people know, this protection is only a film. If the protective layer is damaged , the following steel began to rust , resistant to air, steam, water and other corrosive medium and weak acid, alkali, salt and other chemical etching medium corrosion of steel. socket joint fittings place is the most used terms and chemical aspects of the pressure vessel . General refinery plant has a large demand . Other aspects, such as chemical, food , beverage, pharmaceutical and other industries can be applied . Its main widely used in petroleum , chemical, medical, food, light industry, machinery and other industrial pipeline instrumentation and mechanical structural components.
