304 stainless steel pipe has excellent hygienic performance. It is corrosion resistant, beautiful and grade, and its service life is more than 70 years. It is one of the pipelines with better comprehensive performance. 304 stainless steel water supply pipe is characterized by no rust, stable chemical performance, no two pollution, is a very good green environmental protection material.
Many high-rise buildings in the world use 304 stainless steel pipe as the main pipeline of water supply. For example, the Kuala Lumpur Malaysia communications tower, is the use of 304 stainless steel pipe, its high pressure joints can be up to 421 meters of water supply, the main stainless steel pipe diameter of 318 meters.
304 stainless steel pipe in the air or chemical corrosive medium is a highly corrosion resistant alloy steel. From the angle of metallographic metal, because of containing chromium chemical composition of 304 stainless steel, so on the surface to form a thin protective film of chrome but dense, this film from stainless steel immersed in oxygen continue to penetrate the steel body, which plays the role of corrosion resistance. In order to maintain the corrosion resistance of stainless steel, the chromium content must be higher than 12%. 304 thin wall stainless steel pipe is a versatile stainless steel, and it is also used in a large number of equipment and parts that require good comprehensive performance (corrosion resistance and formability).
The corrosion resistance of the 304 stainless steel pipe is better than that of the 200 stainless steel tube, and the heat resistance is better, and it can withstand the high temperature of 1000-1200 degrees. 304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance.
The corrosion resistance of 304 stainless steel tubes in boiling nitric acid with concentration lower than 65% is very strong. It can also resist alkali solution and corrosion of most organic and inorganic acids. A high alloy resistant to corrosion in air or in a chemically corrosive medium.
