Large carbon steel elbow

Large carbon steel elbow

The production process used by carbon steel elbow manufacturers is mainly: first welding a cross section for polygon polygonal ring shell or two ends of the closed polygonal fan shell, internal pressure medium, with internal pressure, the cross section from polygon gradually into 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.

For the production process of carbon steel elbow, there are the following two advantages:

When making carbon steel elbow, it is not necessary to make 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.

When making carbon steel elbow, blank is flat plate or developable curved 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: diameter 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. 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. Treatment of antirust paint. The ANTIRUST PAINT SHOULD BE OF GOOD PERFORMANCE AND QUALITY, and the painting method should also dip the paint in the pool instead of the brush, and then make sure that every area is even.

Our company mainly produces various types and materials of pipe fitting products, such as: elbow, tee, size head, pipe cap, flange, steel pipe and so on. Welcome customers who need the above pipe fitting products to visit our company and order!
