In a piping system, an elbow is a fitting that changes the direction of a pipe run. According to the angle, there are three kinds of most commonly used: 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 alloy steel, carbon steel, stainless steel, forging, etc.
According to the production process can be divided into: welding elbow, stamping elbow, push elbow, butt welding elbow, etc.
