One of the more commonly used pipe fittings for carbon steel elbows

The use of carbon steel elbow and the use of the device: the carbon steel elbow is used for the connection of the pipe bend. Connect two pipes with the same nominal diameter to turn the pipe as a visual point. The carbon steel elbow is distinguished by the material, butt welding Steel elbow, seamless carbon steel elbow, straight seam carbon steel elbow, stamped carbon steel elbow. Carbon steel elbow is a kind of connecting pipe commonly used in pipeline installations. It is used for the connection of pipe bends. Other names: 90-degree carbon steel elbow, 45-degree carbon steel elbow, and other degrees of elbow.

The basic technical process of carbon steel elbows is: firstly welding a polygonal ring shell with a polygonal cross-section or a polygonal fan-shaped shell with closed ends. After the interior is filled with pressure medium, internal pressure is applied and the cross-section under the effect of internal pressure The polygon gradually becomes a circle, and eventually becomes a circular ring shell. According to need, a circular ring shell can be cut into 4 90 ° elbows or 6 60 ° elbows or other standard elbows. This technology is suitable for manufacturing Any standard large carbon steel elbow with a ratio of the elbow's middle diameter to the elbow's inner diameter greater than 1.5 is currently a better method for making large carbon steel elbows.
