The production and production process of welding elbow bends is described by Zhangzhou Xindingsheng Pipeline Complete Equipment Manufacturing Co., Ltd. as follows:
The welding elbow is made of steel plate as the raw material. Firstly, after the steel plate is cut into materials according to the requirements, it is molded by stamping, and is also punched into a circular shape by punching, and the same two are combined, welded, shaped, etc. due to the weld. Exist, so non-destructive testing is required, and heat treatment is required due to the presence of welding stress.
Welding elbow bends has two more steps than push elbow bends: one is flaw detection, the other is heat treatment, and the other procedures are the same as the elbow manufacturing process. Tube production process. There are also many methods for processing pipe fittings. Many are also in the category of machining, and the most used are stamping, forging, roller processing, rolling, bulging, stretching, bending, and combination processing.
Pipe processing is an organic combination of machining and metal pressure processing.
