What are the classifications and materials of elbows?

Elbows are a commonly used pipe connection that can be classified into different types according to their shape and size characteristics. According to the size of the bending radius, common elbows are divided into long radius elbows and short radius elbows. There are also a variety of elbow angles, such as 90 degrees, 45 degrees, 30 degrees and other different angles of elbows, among which 90 degree elbows are the most common.

There are also a lot of materials for making elbows. Carbon steel elbow is one of the most widely used bending short heads, its corrosion resistance is poor, but relatively low, and it is widely used in general industries. Stainless steel elbows are the pipe connections of choice in high-end industries such as food, pharmaceutical, aerospace, etc. due to their excellent corrosion resistance, high-temperature performance, and mechanical properties.

Because of its excellent stability in high temperature and high pressure environments, alloy steel elbows are widely used in chemical industry, electric power and other fields. Copper and copper-nickel alloy elbows are mainly used in special environments such as marine engineering, while plastic elbows are mainly used in chemical industry, sewage treatment and other fields, which have the advantages of corrosion resistance, insulation, wear resistance and so on.

In addition to the above materials, there are other elbows made of special and open materials, such as titanium alloy elbows, fiber reinforced plastic elbows, ceramic elbows, etc., which are suitable for special occasions and special requirements in pipeline systems.

The structure of the elbow is: bend (upper and lower structure) head (single structure).

The structure of the elbow is: bend (upper and lower structure) head (single structure). The phonetic pronunciation is: Pinyin is: wāntóu.

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

The methods of connection with the pipe are: 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 elbows, stamping elbows, push elbows, casting elbows, butt welding elbows, etc. Other names: 90 degree elbow, right angle bend, love and bend, etc.

The radius of curvature of the elbow is a term (noun) used in the field of engineering, that is, the radius of the curvature, which expresses the degree of bending.

For example, the elbow of 219 is 8*.

According to the radius of curvature of the elbow, it can be divided into long radius section rolling source elbow and short radius elbow. A long-radius elbow refers to the outer diameter of the tube whose radius of curvature is equal to a multiple, i.e., r=; A short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e., r=.

d is the diameter of the elbow, r is the radius of curvature).
