Carbon steel elbow is a pipe fitting that can change the direction of the pipe. According to the angle of the elbow is divided into 45 ° elbow, 90 ° elbow and 180 ° elbow, according to the elbow radius of curvature, can be divided into long radius elbow and short radius elbow. According to the production process can be divided into welding elbows, stamping elbows, pushing elbows, casting elbows, etc. But do you know the production of carbon steel elbows? But do you know what is the process of making carbon steel elbow? What are the advantages? Carbon steel elbow suppliers will give you a detailed description of carbon steel elbow.

Carbon Steel Elbow

Manufacturing process of carbon steel elbow

Polygonal ring shells with polygonal cross-sections at both ends or polygonal fan shells closed at both ends are welded, filled with internal pressure medium, internal pressure is applied, and the cross-section is gradually changed from polygonal to ring shells under internal pressure; then, the ring shells can be cut into four 90° elbows or six 60° elbows or other specifications according to the customer's specific needs.

This carbon steel elbow is manufactured with the following two advantages.

(1) Carbon steel elbow is manufactured from billet as raw material, saving the cost of production equipment and molds, can be obtained any large diameter, thin wall thickness of carbon steel elbow.

(2) Carbon steel elbow manufacturing, the billet flat or unfolded, simple cutting materials, accuracy is easy to ensure, easy assembly and welding.

Due to the above two advantages, can greatly shorten the production cycle, reduce production costs, the process is applicable to the diameter and inside diameter ratio greater than 1.5 of any specifications of the manufacturing of large elbow, is currently the ideal method for manufacturing large carbon steel elbow.

After manufacturing a carbon steel elbow, it does not mean that the work is over, the surface needs to be treated.

Carbon Steel Elbow Surface Treatment

1.Bore problem. As the current carbon steel elbow manufacturers to promote the processing of seamless elbow, the caliber error is small, can not guarantee that the caliber error is within the national standards, so it is necessary to deal with the caliber of carbon steel elbow, so that it conforms to national standards and customer requirements.

2, internal and external scratches and regrinding. When we process the seamless elbow, it will unintentionally leave scratches, so in this case, the carbon steel elbow scratches need to be trimmed or repaired, can be repaired in the pipe fitting shop, can also be repaired again with welding, so that there is no problem.

3. Antirust coating treatment. Anti-rust coatings should be selected with good performance and quality, and should be painted in the pool rather than brushed, and make sure that every place is even.
