Carbon steel elbow knowledge
In addition to carbon, carbon steel elbows generally contain a small amount of silicon, manganese, sulfur, and phosphorus. According to the application, carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel. It is divided into two types: building structural steel and machine-made structural steel. Internal threads on carbon steel elbow fittings are usually tapped. Due to the high viscosity of stainless steel and poor chip breaking performance, it is easy for chips to scratch the workpiece thread or tap chipping during the tapping process, which affects the processing efficiency and thread quality. In order to prolong the service life of the tap and improve the quality of thread processing, the above points should be paid attention to.
The materials used in carbon steel elbows are a large class of new materials with special electric, magnetic, light, sound, heat, force, chemical and biological functions. It is an important basic material, and it also plays an important role in transforming some traditional industries, such as agriculture, chemical industry, and building materials. The material of carbon steel elbow is special, showing different use values in the field, and to some extent affects the development of other industries.
The use and installation of carbon steel elbows: carbon steel elbows are used for the connection of pipeline bends. Connect two pipes of the same nominal diameter to make an angled turn in the pipe. Divide carbon steel elbows, cast steel elbows, alloy steel elbows, stainless steel elbows, copper elbows, aluminum alloy elbows, etc. by material. Carbon steel elbow is a commonly used connection pipe fitting in pipeline installation, which is used for the connection of pipeline bends. 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.
Weld a polygonal annular shell with a polygonal cross-section or a polygonal fan-shaped shell with both ends closed. After the interior is filled with a pressure medium, internal pressure is applied. Under the action of internal pressure, the cross-section gradually changes from a polygon to a circle and finally becomes a circle. ring shell. According to needs, a circular ring shell can be cut into four 90 elbows or six 60 stamping elbows or stamping elbows of other specifications. Large elbows of any size are currently the ideal method for manufacturing large carbon steel elbows.
