Stainless steel elbow

In piping systems, elbows are fittings that change the direction of the piping. According to the angle, there are three kinds of 45 ° and 90 ° and 180 ° most commonly used. In addition, according to the needs of the project, it also includes other abnormal elbows such as 60 °. The difference between stainless steel elbow and carbon steel elbow is mainly the material. The chemical composition contained in the elbow will keep the surface of the elbow from rusting and corrosion for a long time.

The difference between stainless steel elbow and carbon steel elbow is mainly the material. The chemical composition contained in the elbow will keep the surface of the elbow from rusting and corrosion for a long time. Production according to standards can be transformed into:

1. Divided by manufacturing standards, it can be divided into national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

2. Divided by production method, it can be divided into pushing, pressing, forging, casting and so on.

90 ° stainless steel elbow is mainly used for connecting pipe fittings in pipeline installation, and is used for connection of pipe bends. Connect two pipes with the same or different nominal diameters to make the pipe turn 90 °.

Stainless steel elbows are usually made by adding a high proportion of Cr, Ni and other alloys on the basis of carbon steel, and the content ratio can reach more than 20%. Common steel types are: 304, 304L, 321, 316, 316L, 1Cr18Ni9Ti, 0cr18ni9. The first several steel numbers are represented by Japan, the American steel number, and the last (1Cr18Ni9Ti) is the domestic steel number.

Stainless steel characteristics: strength and toughness indicators are the best of all kinds of steels, and its most prominent advantage is corrosion resistance. Stainless steel must be used in corrosive places such as chemical papermaking. Of course, the cost is also high!
