Carbon steel pipe fittings with higher carbon content have better hardness and strength. They are used to connect two pipes with the same nominal diameter to make the pipe turn 90 degrees.
Classifications of carbon steel pipe fittings
Carbon steel can be divided into carbon structural steel, carbon tool steel and free-cutting structural steel according to their uses. Carbon structural steel can be divided into building structural steel and machine-made structural steel. According to the carbon content, carbon steel can be divided into low carbon steel (the content of carbon being less than and equal to0.25%, medium carbon steel (the content of carbon being 0.25% to 0.6%) and high carbon steel (the content of carbon being greater than 0.6%.
Usually, S is less than and equal to 0.055% and P 0.045% for high-quality carbon steel. Carbon structural steel is mainly used for ships, building components, bridges, machine parts, etc. Carbon tool steel is mainly used for knives, molds, measuring tools, etc. Carbon steel pipe fittings are classified according to the use of carbon steel.
Processing carbon steel pipe fittings
The basic process of carbon steel pipe fittings is to weld a polygonal ring shell with a polygonal cross-section or a polygonal fan-shaped shell with closed ends. After the inside is filled with pressure medium, the internal pressure is applied. It gradually becomes a circle and eventually becomes a circular torus shell. According to needs, a circular ring shell can be cut into an elbow. This process is suitable for manufacturing large elbows of any size with a ratio of the pitch diameter of the elbow to the inner diameter of the elbow. It is currently the ideal method for manufacturing large pressure-elbows.

Advantages of carbon steel pipe fittings
The advantages of carbon steel pipe fittings are mainly manifested in the following aspects:
(1) No tube blanks are required as raw materials, which can save the cost of pipe-making equipment and molds, and can obtain elbows with any large diameter and relatively thin wall thickness.
(2) The tube blank is a flat plate or a developable curved surface, so the blanking is simple; the accuracy is easy to ensure, and the assembly and welding are convenient.
The manufacturing cycle can be shortened, and the production cost can be greatly reduced. Because the pipe fitting does not require any special equipment, it is especially suitable for the on-site processing of carbon steel pipe fittings of big sizes.
