Introduction of Elbows

In a pipe system, an elbow is a pipe fitting that changes the direction of the pipe. According to the angle, there are three most commonly used elbows: 45 ° and 90 ° and 180 °. In addition, 60 ° and other abnormal angle elbows are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The connection methods with pipes include direct welding (the most commonly used method), flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Alloy 625 is a nickel base alloy with corrosion resistance and oxidation resistance. The excellent strength and toughness of 625 alloy in the temperature range of low temperature - 1093 ° C are derived from the solid solution effect of the refractory metals columbium and molybdenum in the nickel chromium matrix. The excellent fatigue strength and stress corrosion cracking resistance of alloy 625 are due to the chloride ion in the material.
