What is the processing method of stainless steel elbow fittings?

The processing method of stainless steel elbow pipe fittings is a difficult task, there are many prerequisites that need to be controlled, and there are also many processing methods. The processing of many stainless steel elbows also belongs to the category of mechanical processing, and most of them are stamping method, forging method, rolling method, rolling method, bulging method, stretching method, bending method and combined processing method. Each of these processing methods has its own characteristics, the technical prerequisites used are different, and the matters needing attention are also different.

Pipe fitting processing is an organic combination of machining and metal pressure processing. Good combination technology makes the processing method of pipe fittings more reasonable and more in line with the use requirements of products. Pipe fittings with crimping and back cover, which increase the total strength of the pipe end to crimp the outer or inner side of the pipe or seal the end of the pipe fitting; pipe fittings with changed cross-section, according to the requirements, change the circular section into a square or oval shape , polygon, etc.; flanged and rounded pipe fittings, the former refers to the inner or outer convex of the end of the pipe, and the latter refers to the pipe that forms a bulge or groove in the circumferential direction of the pipe. The technical requirements of these types of pipe fittings are carried out under certain technical requirements, and reasonable processing methods are required, and the processing methods and processes are reasonably manufactured and processed.

The stainless steel flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Stainless steel flanges have threaded connection flanges and welded flanges. It is a disc-shaped part, which is more common in pipeline engineering, and flanges are used in pairs. In pipeline engineering, flanges are mainly used for the connection of pipelines. In the pipelines that need to be connected, various flanges are installed. Wire flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4 kg.

The low-pressure small diameter has a wire flange, and the high-pressure and low-pressure large diameter use welded flanges. The thickness of the flanges and the diameter and number of connecting bolts are different for different pressures. Stainless steel flanges will not produce corrosion, pitting, rust or wear, and are one of the strongest materials in construction metal materials. Because stainless steel has good corrosion resistance, it enables structural components to maintain engineering integrity.
