During the production of
stainless steel pipes, some fixed steps will be taken to complete the entire production operation. During the production process, the hot extrusion process is required for the later finalization. The following is a detailed introduction to the hot extrusion process:
1. For stainless steel pipe, good deformation, internal and external surface quality and metallographic structure can be obtained. The improvement of vertical hydraulic piercing process and equipment can make the wall thickness deviation accuracy of extruded raw pipe reach 5 to 7 percent. Extruder die is simple, easy to manufacture and replace, suitable for small batch, multi specification production. Do you know the hot extrusion process of stainless steel pipe
2. The advantage is that the continuous casting billet can be directly used as raw material, the product quality is stable, and the variety can be changed flexibly. The hot extruded finished pipe can be directly produced, and various profiled stainless steel pipes can also be produced. For varieties with high requirements, the production process of pre drilling, hydraulic perforator reaming and extruding is generally adopted. Do you know the hot extrusion process of stainless steel pipe
3. A solid blank is directly punched and extruded into a tube on a vertical hydraulic piercing machine; The billets used for medium specification steel pipes shall be pre drilled with small holes as far as possible, reamed with vertical hydraulic puncher and extruded into pipes; The billets used for large specifications are pre drilled with large holes, and then directly enter the extruder to extrude into tubes. Obviously, the extrusion method is used to produce finished pipes and provide raw materials for cold processing. Do you know the hot extrusion process of stainless steel pipe
The stainless steel pipes we usually see are basically of various styles, and their specifications and models are basically many. In the process of forming, hot extrusion process is required to carry out the forming operation.
