114Carbon steel elbow manufacturer
Carbon steel elbow elbow manufacturers use the following manufacturing process processing: first welding a cross section for polygon polygonal ring shell or two ends of the closed polygonal fan shell, internal pressure after the internal pressure medium, the cross section from polygon gradually become a circle, let it become a circular ring shell; Then according to the specific needs of customers, the circular ring shell can be cut into 4 90° elbow or 6 60° elbow or other specifications elbow.
This kind of carbon steel elbow has the following two advantages:
One is carbon steel elbow production, is not the need to pipe billet as raw material. The cost of pipe equipment and die can be saved, and the carbon steel elbow with any large diameter and relatively thin wall thickness can be obtained.
Second, when the carbon steel elbow is made, the blank is flat or developable surface. Therefore, the cutting is simple, the precision is easy to ensure, and the assembly and welding are convenient.
Because OF THE ABOVE two advantages, THE manufacturing cycle can be shortened, the production cost can be greatly reduced, the process is suitable for the manufacture of various specifications of large elbow with the ratio of elbow middle diameter to elbow inner diameter greater than 1.5, is currently the ideal method for the manufacture of large carbon steel elbow.
Carbon steel elbow production, does not mean the end of the work, but also need to do the surface treatment. Surface treatment of carbon steel elbow including:
1. Caliber problem. Because the current carbon steel elbow manufacturers in the process of seamless elbow, there will be a little error in the caliber, can not ensure that the caliber error is within the scale of the national standard, so we need to deal with the caliber of carbon steel elbow, so that they meet the standards and customer requirements.
2. Internal and external scratches and grinding. When we push and process seamless elbow, we will inadvertently leave scratches, so in this case, for carbon steel elbow scratches, is needed to be ground or repaired, can be repaired in the pipe fitting factory, can also use electric welding repair and grinding, so that there is no problem.
