Stainless steel pipe is a kind of pipe fitting, it is made of stainless steel materials, so called stainless steel pipe fittings, it includes stainless steel elbow, stainless steel tee, four-way stainless steel stainless steel tube, stainless steel reducer, cap, etc., according to join method can be divided into the socket type stainless steel pipe fittings, forever China pipe threaded stainless steel pipe fittings, stainless steel pipe fittings and flanges, welded stainless steel pipe fittings four classes.
Stainless steel pipe fitting is a kind of new pipe fitting with a wide range of USES. Generally speaking, the processing methods are as follows:
1, forging: die forging machine will be the end of the pipe or part of the punching, so that the outer diameter is reduced, commonly used die forging machine has rotary, connecting rod type, roller type.
2, roller method: in the stainless steel yonghua hydraulic pipe joint tube inside the core, the external use roller push pressure, circular edge processing.
3, stamping method: in the punch press with taper core will be expanded to the desired size and shape.
4, bending forming method: there are three methods more commonly used, a method called stretch method, another method called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the distance of the fixed roller, finished pipe fitting is bent.
5, rolling method: general inyonghua transition joint used spindle, suitable for thick wall tube inside round edge.
6, swelling method: one is to place rubber in the tube, the top of the punch compression, so that the tube convex shape;Another method is called hydroforming, in which liquid is filled in the middle of the pipe and the pressure of the liquid pushes the pipe into the desired shape. This method is used in most bellows production
