stainless steel flange dimensions have two processes of flaw detection and heat treatment in the manufacturing process than other pipe fittings. The other programs are the same. Because some flanges are handled improperly, they will be distorted, which is not allowed. In addition, after the head is pushed, the outer diameter of the front end is generally large, and it is shaped by a shaping die. Due to the presence of welds, non-destructive testing is required. Heat treatment is also required due to the presence of welding stress.
