WPB elbow

WPB elbow is also called stamping welding elbow. It is an elbow made of the same material as the pipe, punched into a half ring elbow with a stamping die, and then assembled and welded into two half ring elbows

WPB elbow is processed by stamping, and stamping is completed by stamping die and stamping equipment. High speed pressure can reach hundreds or even thousands of times per minute, and each stamping stroke may be affected by one stamping part. Therefore, stamping elbow has high production efficiency and consumes less time than hot pressing elbow

WPB elbow, also known as pressed elbow or seamless elbow, is a commonly used connection pipe fitting in pipeline installation. It connects two pipes with the same or different nominal diameters to make the pipeline turn at a certain angle

WPB elbow is complex, and it needs to be welded according to different materials and uses, and gradually formed under the determined pressure. The forming of stamping elbow shall be carried out according to the determined process, and the corresponding process shall be strictly followed, otherwise the stamping elbow produced will have quality problems. As required, a circular ring shell can be cut into four 90 ° elbows or six 60 ° elbows or elbows of other specifications. This process is applicable to manufacturing large push elbows of any specification with the ratio of elbow pitch diameter to elbow inner diameter greater than 1.5D. It is an ideal method for manufacturing large push elbows at present

This process molding method is used in the production of different elbows, showing good use value in different industries, so that the process has good value in the production of different elbows

The advantages of the forming process of large WPB elbows are mainly shown in the following aspects:. The raw material of the stamping elbow is special, and it does not need to add the raw material of the tube blank, so it is easy to control during processing

⑵ The blank for processing stamping elbow is flat plate or developable curved surface, so the blanking is simple, the accuracy is easy to protect, the assembly and welding are convenient, the raw materials are easy to control during processing, the operation is simple, there is no complicated process, and the welding and assembly are convenient

⑶ Due to the above two reasons, the manufacturing cycle can be shortened and the production cost can be reduced. Because no one-to-one equipment is needed, it is especially suitable for processing large stamping elbows on site
