Processing technology of stainless steel pipe cap

Processing technology of stainless steel pipe cap  The stainless steel pipe cap is used to connect the pipe into one end of the pipe.  Stainless steel pipe fittings can be divided into socket fittings, threaded fittings, flanged fittings and welded fittings according to the connection mode.  Stainless steel pipe fittings are also a kind of pipe fittings, because they are made of stainless steel material, so they are called stainless steel pipe fittings.  Stainless steel pipe fittings include stainless steel elbow, stainless steel tee, stainless steel tee, stainless steel reducing pipe, stainless steel pipe cap, etc., which can be divided into socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe fittings according to the connection mode.  Stainless steel elbow for pipe fittings turning place;  Flanges are used to connect pipes to each other and parts to the pipe end.  Stainless steel reducing pipe is used to connect two pipes with different diameters. The main stainless steel material is 304, 304L, 316, 316L.

 Stainless steel pipe fittings are the general name of all kinds of stainless steel pipe fittings, which can be divided into different categories according to shape, use and connection mode.  With convenient installation, excellent performance, durable and other characteristics, widely used in the construction and installation of various pipelines.

Stainless steel pipe fitting is a new type of pipe fitting widely used.  Generally speaking, the treatment method is as follows:

Forging: stretch the end or part of the pipe with a type forging machine to reduce the outer diameter.  Common rotary forging machine includes rotary, connecting rod type and roller type.

Rolling method: put the tube core into the stainless steel pipe fitting, and press it outside with a roller for circular edge processing.

Stamping: Expansion of the pipe end to the desired size and shape with a tapered core on the punch.

Bending molding method: there are three commonly used methods, one is called stretching method, one is called stamping method, the third kind of roller method has 3-4 rollers, two fixed rollers and an adjustment roller to adjust the fixed roller spacing.  Finished pipe fittings are bent.

Rolling method: generally without mandrel, it is suitable for the inner round edge of thick wall pipe.

Bulge method: put the rubber into the tube and press it with a punch to make the tube protrude and form;  Another method is hydraulic bulging, which fills the middle of the pipe with liquid. The pressure of the liquid expands the pipe into the desired shape. This method is used in the manufacture of bellows.
