Pipe fitting is a part of connecting pipe to pipe line. According to the connection method can be pided into the socket type pipe fittings, threaded pipe fittings, flanges and welded pipe fittings four categories. Made of the same material as the pipe. Elbow, flange, three – way, four – way pipe and pipe, etc.. A place where the pipe is connected to the pipe, and the pipe is connected to the pipe end. The three way pipe is used for the collection of the four pipe; the other is the place where the four pipe is collected; the same is used for connecting the ground with two tubes of different diameters. Pipe fittings are very large, but in our country, some of the difference, in Japan, whether it is a sample or information, pipe type a lot, all kinds of. If you want to give the next definition, I think that all the products through deep processing and production of products should belong to the category of tube. Japan did so. So, since it is a pipe to do raw material through deep processing into a product, so, this product has the dual characteristics of pipe and mechanical parts, is the combination of the two. Pipe is the necessary raw material, but the processing method of the pipe is a lot of, as long as the method of mechanical processing, it can be applied.

Stainless steel slip on flange drawing convenience, simple manufacture, low cost, widely used; but less rigid. Therefore, it cannot be used for supply and demand, flammable, explosive and high vacuum degree requirements of chemical process piping system and height, is extremely harmful to the occasions. Seal type plane and surface process. The forging of stainless steel slip on flange according to the movement of forging die, forging and rotary forging, rotary forging, roll forging, cross wedge rolling, ring rolling and cross rolling etc.. Rotary forging, rotary forging and rolling pendulum ring forging process is also available. With a process or a few steps may complete the fine processing of complex forgings. As a result of the absence of the flying edge, the stress area of the forging is reduced, and the required load is also reduced. But should be careful not to be restricted completely blank, therefore to strictly control the blank size, relative position control of forging die and forging of were measured efforts to reduce die wear. When the temperature is over 300-400 (the blue brittle zone of the steel), the deformation resistance will be reduced sharply, and the deformation can be improved greatly. According to in different temperature regions of forging in forging quality and process requirements of different stainless steel slip on flange can be pided into cold forging, warm forging, hot forging three molding temperature region. There is no strict boundaries of the pision of this temperature region, generally speaking, in the region of the temperature of the forging is called hot forging, not heated at room temperature of the forging is called cold forging.
