Carbon steel elbow is a metal pipe fitting to change the direction of the pipeline on the carbon steel pipeline. Connection methods include wire fastening and welding. According to the angle， there are 45 ° and 90 ° 180 ° three of the most commonly used， in addition， according to the needs of the project also includes 60 ° and other non-normal angle elbow. Elbow materials include cast iron， stainless steel， alloy steel， malleable cast iron， carbon steel， non-ferrous metals and plastics. Connected with the pipe in the following ways: direct welding (the most commonly used way) flange connection， hot melt connection， electrofusion connection， threaded connection and socket connection. According to the production process can be divided into: welding elbow， stamping elbow， pushing elbow， casting elbow， etc.. Other names: 90-degree elbow， right-angle bend.

Basic Processes

First weld a polygonal cross-section of the polygonal ring shell or two closed ends of the polygonal fan shell， the internal flushing full of pressure medium， applying internal pressure， the cross-section of the polygon under the action of the internal pressure gradually become round， and eventually become a circular ring shell. According to the need， a circular ring shell can be cut into four 90 ° elbow or six 60 ° elbow or other specifications of the elbow， the process is suitable for the manufacture of elbows and elbow diameter ratio of any specifications of the elbow greater than 1.5 times the inside diameter of any large elbow， is the manufacture of large carbon steel elbow is the ideal method.
