The characteristics of forming process of high pressure alloy elbow

The forming process of high pressure alloy elbow is complicated and needs to be welded according to different materials and uses. The forming of high pressure alloy elbow needs to be carried out according to a certain procedure, and the corresponding process is strictly observed. Otherwise, the production of high pressure alloy elbow will produce quality problems.
Alloy high pressure bend forming technique of the basic process is: first of all welding a cross-sectional polygon polygon ring shell or closed at both ends of the multiple edges of fan-shaped shells, when 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 to become the a circular ring shells. This is the process of high pressure alloy elbow forming process.
The advantages of the forming process of high pressure alloy elbow are mainly manifested in the following aspects:
(1) without the need of pipe blank as raw material, the cost of pipe making equipment and die can be saved, and the high pressure alloy elbow with a relatively thin wall thickness can be obtained. The raw material of the high pressure alloy elbow is special, and the raw material of the pipe blank is not needed to be added in the process of processing.
(2) processing of high pressure alloy elbow blank is flat or developable surface, and thus a simple material, to ensure accuracy. Assembly welding is convenient, in the processing of easy control of raw materials, simple operation, no complicated process and welding and assembly is convenient.
(3) due to the above two reasons, the high pressure alloy elbow can shorten the manufacturing cycle, and the production cost is greatly reduced. Because no special equipment is needed, the high pressure alloy elbow is especially suitable for the field processing.
