Screw pipe fitting elbows are formed by casting

　　Screw pipe fitting elbows are formed by casting a half ring screw pipe fitting elbow with a casting die of the same material as the pipe, and then two half ring Casting Stainless Steel 90 Degree Screw Pipe Fitting Elbow is welded together. Because of the different welding standards of all kinds of pipelines, the fixed semi-finished products are usually manufactured by group spot welding, and the field construction is carried out according to the weld grade of pipelines. Therefore, it is also called screw pipe fitting elbow.

　　The forming process of screw pipe fitting elbow is complex. It needs to be welded according to different materials and uses, and gradually formed under certain pressure. The forming of screw pipe fitting elbow should be carried out in accordance with certain process and strictly follow the corresponding process, otherwise the screw pipe fitting elbow produced will produce quality problems. According to the requirement, a circular ring shell can be cut into four 90 degree screw pipe fitting elbow or six 60 degree screw pipe fitting elbow or other screw pipe fitting elbow. This process is suitable for casting elbows.
