Differentiation and classification of stainless steel elbow

Stainless steel elbow is a series of elbow products, the difference is that his production of raw materials for stainless steel.

Stainless steel elbow is different from the carbon steel elbow of the main material, its chemical composition will keep the surface of the elbow for a long time will not rust, will not be corroded.

In the pipeline system, the elbow is the pipe fittings to change the direction of the pipeline. The stainless steel elbow is commonly used in 45 degrees, 90 degrees, and 180 degrees according to the Angle. In addition, it also includes 60 degrees and other angles according to the engineering needs of customers.

Pipe fittings are made of stainless steel, carbon steel, alloy steel, cast iron, non-ferrous metals and plastics.Pipe fitting and pipe connection mode: direct welding, flange connection, electric fusion connection, thread connection, etc.Elbow according to the production process can be divided into: welding elbow, stamping elbow, hot pressing elbow, push elbow, casting elbow, forging elbow, etc.

90 degree elbow: right Angle bend, love and bend, white steel elbow and so on.

Elbow according to the manufacturing standard is divided into: national standard, ship standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

Elbows are made by pushing, pressing, forging, casting and so on.

Stainless steel elbow is usually on the basis of carbon steel increased a high proportion of Cr,Ni and other alloys, the content ratio can reach more than 20%.Common are: in steel 304304 L, 321.316.616 l. 1 cr18ni9ti, 0 cr18ni9.The first few numbers of the steel number for Japan, the United States steel number method, the last one (1Cr18Ni9Ti) for the national standard steel number method.

Stainless steel characteristics: strength, toughness refers to all kinds of steel in the good, its most prominent advantage is corrosion resistance, in chemical paper and other corrosive occasions must use stainless steel, of course, the cost is higher!
