Carbon steel elbow is change on the carbon steel pipe line direction of metal pipe fittings.Connection with thread and welding.Points according to the Angle 45 ° and 90 ° 180 ° three most commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend.Elbow materials have cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic, etc.With the pipe connection mode: direct welding (way) of the most commonly used flange connection, hot melt connection, fused connection, threaded connection and socket type connection, etc.According to the production process can be divided into: welding bend, stamping elbow, pushing system bend, casting bend, etc.Other names: 90 degrees bend, right-angle bend, such as love and curved

 

Carbon steel elbow, first of all, according to its radius of curvature to points, can be divided into long radius elbow and short radius elbow.Long radius elbow refers to its radius of curvature is equal to 1.5 times the pipe diameter, R = 1.5 D.Short radius elbow refers to its radius of curvature is equal to the pipe diameter, R = 1.0 D.To bend diameter (D, R for the radius of curvature. D times can also be used to say.

 

Use the material for the production of raw materials of elbow can be called carbon steel elbow

90 ° carbon steel elbow

Points: according to the Angle 45 °, 90 ° and 180 ° of the three common elbow, otherwise the project need, can customize special such as 60 ° or other point of view, etc.

Carbon steel pipe and connection mode: welding, flange connection, threaded connections, such as socket connection form.

According to the process forms can be divided into: welding bend, punching bend, casting bend, etc.

Purpose: connecting the two pipes, pipe to change direction, to 45 ° or 180 ° and 90 ° direction or other turning Angle.

Manufacturing standards: gb, American standard, Japanese standard, German standard, the standard.

Carbon steel elbow basic process is: first, welding a cross section of a polygon or both ends closed multi multi ring shell fan shell, internal filled with medium pressure, with inner pressure and internal pressure under the action of cross section of polygonal gradually became round, and eventually become a circular ring shell.According to the need of a circular ring shell can be cut into four 90 ° bend or six 60 ° elbow or other specifications elbow, diameter and in the process is suitable for manufacturing elbow bend diameter ratio greater than 1.5 times of any size large elbow, is an ideal method to manufacture large carbon steel elbow.
