The seamless elbow is made by equipment

A seamless bend is a common pipe connector used to change the flow of pipes in a pipe system. It is usually composed of elbow body, elbow inner and outer wall coating, internal and external welds, flaw detection and appearance inspection. The production and molding process of seamless elbow is complex, which needs to go through multiple processes and strict quality control. The following will be a detailed introduction to the production of seamless elbow molding process, including material selection, processing technology, inspection standards and other aspects.

First, material selection

1. Elbow body material: usually made of carbon steel, alloy steel, stainless steel and other materials. When selecting materials, it is necessary to consider the working conditions, media, temperature, pressure and other factors of the pipeline system to ensure that the elbow material has sufficient strength and corrosion resistance.

2. Elbow inner and outer wall coating: In order to increase the corrosion resistance of the elbow, it is usually coated with an anti-corrosion layer or coating on the inner and outer walls, such as epoxy resin, polyethylene, etc.

Second, processing technology
