Key points of making carbon steel elbow  

The production points of carbon steel elbow pipe fittings are mainly divided into the following: the use of carbon steel elbow pipe fittings should be kept dry, to prevent the electrode from being contaminated with oil and other dirt, so as not to be affected in the use of the weld.  Carbon steel elbow pipe fittings in welding, in the use of medium carbon steel elbow pipe corrosion resistance.  After welding, it is easy to crack.  Using the same electrode welding, requires more than 300 degrees Celsius of heat and post-weld cold treatment of about 700 degrees Celsius.  

Carbon steel elbow pipe fitting is a common connection pipe fitting in the installation of water heating, used for pipe connection at the corner, used to change the direction of the pipeline.  Carbon steel elbow pipe fittings are also called stamping elbow, seamless elbow, straight seam elbow, welding elbow, right Angle elbow and so on.  

The purpose of carbon steel elbow: to connect two pipes with the same or different nominal diameter, so that the pipe can be turned at various angles, such as 45 degrees, 90 degrees, 180 degrees and various angles.  Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and greater than 1.5 times of pipe diameter belongs to elbow.  

Carbon steel elbow molding process is the adoption of a common elbow push system machine, core mold and heating equipment, mainly is set on the mould of billet in pushing forward movement, under the impetus of the machine in motion is heated, hole diameter and bending forming process, heat bend molding process has good appearance, uniform wall thickness and continuous operation, the main characteristics can make the mass production,  Therefore become carbon steel alloy steel and other elbow pipe fittings.
