Stainless steel elbow is the steel plate according to the requirements of cutting material, molding, but also through the die stamping into a round, with two identical and then combined, welding, adjustment and so on. So how is the production process of stainless steel elbow produced?
1. Cold pressing bending molding process, using a bend forming machine to put the tube blank into the outer mold. After the upper and lower die is closed, under the action of the push rod, the tube blank moves along the gap reserved by the internal and external die to complete the forming process. The cold pressing process requires high precision of the internal and external molds used.
2. Hot pressing bending molding process, the tube blank is heated, and then processed by specialized equipment. The elbow is heated above the critical temperature, held for a period of time, and then a quenching agent is added.
Stainless steel elbow pressing is a process method of pressing tube billet with pressing fixture on hydraulic press, which is divided into hot pressing bending and cold pressing bending. In the process of installation and layout of the pipeline project, if the stainless steel pipe needs to change the direction, it is necessary to use stainless steel elbow for conversion, and then use stainless steel pipe to connect the other end of the elbow, so that the direction of the pipeline can be changed.
