In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° 180 °. In addition, according to the needs of the project, there are other abnormal angle elbows such as 60 °. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The ways to connect with the pipe include: direct welding (the most commonly used way), flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, hot pressing elbow, pushing elbow, casting elbow, forging elbow, clip elbow, etc. Other names: 90 ° elbow, right angle bend, airbend, white steel elbow.
stainless steel elbow
The main difference between stainless steel elbow and carbon steel elbow is the difference in material. The chemical composition contained in it will keep the elbow surface from rusting and corrosion for a long time. Made according to the standard, it can be converted into:
1. According to the manufacturing standards, it can be divided into national standard, ship standard, electric standard, water standard, American Standard, German standard, Japanese standard, Russian standard.
2. According to the manufacturing method, it can be divided into pushing, pressing, forging, casting.
3.90 ° stainless steel elbow is mainly used as a connecting pipe fitting in pipe installation, which is used for the connection at the bend of the pipe. Connect two pipes with the same or different nominal diameter to make the pipe turn 90 °.
