High pressure elbow

The materials for high-pressure elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. There are several ways to connect pipes, including direct welding (commonly used methods), flange connection, hot melt connection, electric fusion connection, threaded connection, and socket connection. According to production processes, it can be divided into: welded elbow, stamped elbow, hot pressed elbow, push elbow, cast elbow, forged elbow, clamp elbow, etc. Other names: 90 ° elbow, right angle bend, Aier bend, white steel elbow, etc

According to standard production, it can be divided into:

1. According to manufacturing standards, it can be divided into national standards, ship standards, electrical standards, water standards, American standards, German standards, Japanese standards, Russian standards, etc.

According to the production method, it can be divided into pushing, pressing, forging, casting, etc

90 ° stainless steel elbow is mainly used as a connecting pipe fitting in pipeline installation, for connecting at pipe bends. Connect two pipes with the same or different nominal diameters and make a 90 degree turn in the pipeline

Stainless steel is usually made by adding a high proportion of alloys such as Cr and Ni to carbon steel, with a content ratio of over 20%. Common steel grades include: 304304L, 321316316L, 1Cr18Ni9Ti, 0cr18ni9. The first few steel grades represented by numbers are from Japan and the United States, while the last one (1Cr18Ni9Ti) is the domestic steel grade representation method

Characteristics of stainless steel: The strength and toughness indicators are among the best among various steels, and its outstanding advantage is corrosion. Stainless steel is needed in highly corrosive environments such as chemical and papermaking, and of course, the cost is also high
