Production process of high pressure elbow

Process for making high pressure elbow first welding a cross-sectional polygon polygon ring shell or closed at both ends of the multiple edges of fan-shaped shells, interior flushes the full pressure medium, subjected to internal pressure, internal pressure under the effect of cross section by the polygon gradually became round, eventually becoming a circular ring shells. Root according to need, a circular ring shells can cut into four 90 elbow or six 60 high pressure elbow or other specifications of the high pressure elbow and the process application in the manufacture of high pressure elbow diameter and stamping elbow diameter ratio greater than 1.5 any specification of large elbow is currently manufacturing large GB elbow to.

High pressure elbow for petroleum, pipeline system of natural gas, chemical, water, construction, boiler and so on industries. Do not need billet is used as a raw material, save the tube making equipment and the mold expense, and can be arbitrary large diameter and wall thickness relatively thin GB elbow. Due to the above two reasons, to shorten the manufacturing cycle, and the production cost is greatly reduced. Because it does not need any special equipment, and is especially suitable for in field processing large GB elbow. Blank is flat or can be developable surfaces, and thus a simple material, to ensure accuracy. The assembly welding is convenient.
