The Classification of Pipe Elbows

A pipe elbow is a kind of pipe fitting commonly used in pipe installation. It connects two pipes, and is the necessary joint for turning in pipeline engineering.

The hot-pressed elbow, made by hot-pressing technology, is mainly used to change the direction of the pipe. The treatment method of the pipe elbow is mainly quenching and normalizing.

A high-pressure elbow is a kind of pipe fitting used in the bend of high-pressure pipes. It is usually made by high-quality cast steel, stainless steel or alloy steel, which enables the the elbow to bear high pressure and the corrosion of fluids in various high-pressure pipes.

Stainless steel elbows are made from chromium, which can prevent the elbow surface from rusting for a long time and has corrosion resistance.

Welded elbows are formed by steel hot pressing or forging. According to the curvature radius, they can be divided into long radius welded elbows and short radius welded elbows.

The socket elbow is a common pipe fitting generally used when two sections of pipes need to be connected at a right angle.

The manufacturing process of wear-resistant elbows is that the ceramic pieces of wear-resistant elbows are attached to the inner wall of the elbow with inorganic high-temperature adhesive. Ceramics are inorganic so that they are free from oxidation corrosion and resistant to acid and alkali corrosion.

An anticorrosive elbow refers to the steel pipe elbow which can effectively prevent or slow corrosion caused by chemical or electrochemical reaction during transportation and use.

A reducing elbow is also called a reducer elbow which adopts cold working.

The galvanized elbow is to coat the surface of the elbow with zinc to improve its corrosion resistance.
