Stainless steel joints are mainly used to connect various pipes into pipes. With the rapid development of economic construction of stainless steel joints, stainless steel joints have been widely used. Through the analysis of the corrosion resistance of the passivation layer on the surface of stainless steel, combined with the application of advanced production technology and equipment, the production meets the needs of production and life. High-quality stainless steel fixtures fill the domestic gap.
Stainless steel fittings are a type of tubing. It is made of stainless steel, so it is called stainless steel pipe fittings. Including: stainless steel elbow, stainless steel tee, stainless steel cross, stainless steel reducer, stainless steel cap, etc. Pipes can be divided into socket type stainless steel pipe fittings, threaded stainless steel pipe fittings, flange type stainless steel pipe fittings and welded stainless steel pipe fittings according to the connection method. Stainless steel elbows are used at the bend of the pipeline; flanges are used to connect the part of the pipeline and connect to the end of the pipeline. The junction of the three pipes adopts a stainless steel tee pipe; the junction of the four pipes adopts a stainless steel tee pipe; the stainless steel reducing pipe is used to connect two pipes of different diameters.
Stainless steel joints have been widely used in various fields of national economic construction, such as pharmaceuticals, food, beer, drinking water, biotechnology, chemical industry, air purification, aviation, nuclear industry, etc. It has a great impact on people’s production and life.
Stainless steel fittings have great advantages in terms of corrosion resistance. The petrochemical, aerospace, and nuclear power industries are more recommended to use stainless steel.
1. Why does stainless steel not rust?
The essence of stainless steel not rusting is that when stainless steel is exposed to gas, a passivation film is rapidly formed on the surface, thereby preventing further oxidation. This passivation film has strong acid resistance. Corrosion resistance. But it also rusts in some special environments, such as: humid environment and its salty sea fog.
2. About 304, 316, 316L
304 stainless steel is a common material also known in the industry as 18/8 stainless steel. It has the characteristics of good processing performance and strong toughness, and is generally suitable for industrial and furniture decoration fields.
The carbon content of 316 is larger than 0.08%, and the strength of 316 is usually slightly higher than that of 316L material. Generally, 316 material is used for ferrule joints.
316L has a larger carbon content of 0.03% and has better corrosion resistance. It is recommended to use 316L for product materials that must be welded.
Compared to carbon steel joints, stainless steel joints can be ground and polished to obtain a bright, glossy appearance, but carbon steel needs to be quickly coated with a clear coating or paint after polishing, otherwise carbon steel will eventually lose its luster and eventually rust, Stainless steel is unnecessary.
