Manufacturing technology of large carbon steel elbow

Large carbon steel elbow manufacturers mainly produce satisfactory products, obtain customer satisfaction and long-term cooperation.

The manufacturing process of large carbon steel elbow is: first of all, welding a cross section of polygon polygonal ring shell or both ends of the closure of the polygonal fan shell, internal pressure after the internal pressure medium, under the action of cross section from polygon gradually into a circle, become a circular ring shell. According to the requirements, a round ring shell can be cut into 4 90 or 6 60 elbow or other specifications of elbow, this process is suitable for the manufacture of any size of large elbow to elbow inner diameter ratio greater than 1.5, is currently the ideal method for the manufacture of large carbon steel elbow.

The advantages of the carbon steel elbow manufacturing process are mainly shown in the following aspects:

(1) without pipe billet as raw material, the cost of pipe making equipment and mold 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 cutting is simple, the accuracy is easy to ensure, and the assembly and welding are convenient.
