Processing method of Carbon Steel Pipe Fitting Bend

　　Large Size 90deg 5D Carbon Steel Pipe Fitting Bend processing methods also have many kinds. Many also belong to the category of mechanical processing, the most used are stamping, forging, roller processing, rolling, bulging, stretching, bending, and combined processing. Pipe fitting is an organic combination of machining and metal pressure processing.

　　Forging and pressing method: the end or part of the pipe should be punching with the swaging machine to reduce the outer diameter. The commonly used forging machines are rotary, connecting rod and roller.

　　Stamping method: the pipe ends are extended to the required size and shape on the stainless steel elbow with taper core.
