Carbon steel elbow is a metal pipe that changes the direction of the carbon steel pipe. The connection mode is threaded and welded. According to the Angle, there are three kinds of 45° and 90°180° commonly used, in addition according to the engineering needs also include 60° and other abnormal Angle elbow.
Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics, etc. The ways to connect the pipe are: direct welding (common way) flange connection, hot melt connection, electric melt connection, thread connection and socket type connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on. Other names :90 degree bend, right Angle bend, love bend and so on.
(1) Without tube blank as raw material, the cost of tube making equipment and mould can be saved, and the carbon steel elbow with arbitrary large diameter and relatively thin wall thickness can be obtained.
(2) The blank is flat or developable surface, so the feeding is simple, the precision is easy to perfect, and the assembly and welding are convenient.
(3) Due to the above two reasons, the manufacturing cycle can be shortened and the production cost greatly reduced. Without any special equipment, it is especially suitable for processing large carbon steel elbow on site.
(4) Carbon steel elbow is suitable for petroleum, natural gas, chemical, hydropower, construction and boiler industries and other pipeline series.
