What is an elbow? Carbon steel elbow fittings are used for the connection at the bend of the pipeline. Connect two pipes of the same nominal diameter to make an angled turn in the pipe. Elbows can be divided into 90° elbows, right-angle elbows, S-bends, stamping elbows, pressed elbows, machine-made elbows, welding elbows, etc. by type. Divide carbon steel elbows, cast steel elbows, alloy steel elbows, stainless steel elbows, copper elbows, aluminum alloy elbows, etc. by material. Elbows can be said to be used in all walks of life across the country, ranging from small families to large enterprises. Each carbon steel elbow has its own advantages and uses. The carbon steel elbow is a commonly used connection pipe fitting in pipeline installation, and it is used for the connection at the bend of the pipeline. Carbon steel elbows can be favored by the market and continue to replace some traditional wear-resistant materials. The fundamental reason is its excellent product quality and its compatibility with traditional wear-resistant materials. The development and application of these steels has developed rapidly. Because these steels have good wear resistance and toughness, the production process is relatively simple, and the comprehensive economy is reasonable. They are suitable for many working conditions and are welcomed by users. This also makes the application of thick-walled wear-resistant elbow more extensive, and the cost is lower and lower.

The purpose of the 90-degree elbow: to connect two pipes with the same or different nominal diameters, so that the pipeline can make turns of 90°, 45°, 180° and various degrees.

Bending radius less than or equal to 1.5 times the pipe diameter belongs to the elbow, and greater than 1.5 times the pipe diameter belongs to the elbow.
