Production process of elbow: pressing stereotype
Production process of elbow: pressing stereotype
For the big size elbow, for example , more than DN900 ,36″ elbows, it is very difficult to produce them from the steel pipes . So they are commonly made from the steel plates, pressing the plate to the shape of half elbow, and welding the two halves together. Because of the elbows are welded in its body , the inspection of the welding joint is necessary . Commonly we use the X-Ray inspection as the NDT.
