How to process stainless steel flange?

Stainless steel flange fittings are made of steel plate. The steel plate is cut as required and shaped like a UOE, also by punching into a circular shape. There are two halves and then they are pieced together and welded together. After pushing, the flange should be reshaped in this thermal state. After finishing the shape, the outer diameter and wall thickness of flange pipe fitting meet the requirements. Stainless steel flange pipe fitting has the best pressure resistance, temperature and pressure resistance, good flexibility and heat resistance. Stainless steel flange pipe fitting is easy to install and has good thermal conductivity, which is suitable for floor heating system.Flange pipe fittings have excellent impact strength, can be hot melt welding and mechanical connection, better than pb-pp-r thermal conductivity. Finish the process, after shot peening, remove the iron oxide from the internal and external surface of the flange pipe fitting, and groove the two ends for easy welding. After inspection, steel word, painting, packaging and other processes, can leave the factory.Stainless steel flange pipe fittings in the production process than other pipe fittings more flaw detection and heat treatment process. All other programs are the same. Because some flanges will twist when not handled properly, which is not allowed. In addition, the head is generally large outside diameter of the front end, through the plastic mold for shaping. Nondestructive testing is necessary because of the weld seams. Heat treatment is required because of the presence of welding stress.Stainless steel flange processing method also has many kinds. Many also belong to the category of mechanical processing, the most used is stamping method, forging method, roller processing method, rolling method, bulging method, stretching method, bending method, and combined processing method.
