Corrosion resistance of pipe cap

　　The pipe cap is resistant to weak corrosive medium such as air, steam and water and chemical corrosive medium such as acid, alkali and salt. In practical application, steel resistant to weak corrosive medium is often called stainless steel pipe cap, while steel resistant to chemical medium is called acid resistant steel. Because of the difference in chemical composition, the former is not necessarily resistant to chemical medium erosion, while the latter is generally stainless.

　　Stainless steel pipe cap will not produce erosion, pitting, corrosion or wear. Stainless steel is still one of the strongest metal materials used in construction. Because stainless steel has good corrosion resistance, it can make the structural components permanently maintain the integrity of the engineering design. Chromium stainless steel pipe cap also integrates mechanical strength and high extensibility, which is easy to process and manufacture components, and can meet the needs of architects and structural design staff. All metals react with oxygen in the atmosphere to form oxide films on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel inherits oxidation, which makes the corrosion expand and eventually form holes. The carbon steel surface can be guaranteed by painting or electroplating on oxidation resistant metals (e.g., zinc, nickel and chromium), but, as is known, this protection is only a thin film.
