What Are the Connection Methods for Stainless Steel Parts Processing?
Stainless steel parts processing classifies stainless steel pipe fittings into socket pipe fittings, threaded pipe fittings, flanged pipe fittings, and welded pipe fittings based on their connection methods. Generally, the processing methods are as follows:
Forging Method: The pipe end or a section is stretched using a forging machine to reduce the outer diameter. Common rotary forging machines include rotary type, link type, and roller type.
Rolling Method: A mandrel is placed inside the stainless steel pipe fitting, and rollers are used to press the outer surface for edge rounding.
Stamping Method: A tapered core on the punch is used to expand the pipe end to the required size and shape.
Bending Forming Method: There are three common methods: one is called the stretching method, another is the stamping method, and the third is the roller method, which uses 3-4 rollers, including two fixed rollers and one adjustable roller to adjust the distance between the fixed rollers. The finished pipe fitting is bent.
Rolling Method: This method generally does not use a mandrel and is suitable for inner edge rounding of thick-walled pipes.
Bulging Method: Rubber is placed inside the pipe and compressed with a punch to bulge the pipe into shape. Another method is hydraulic bulging, where the middle of the pipe is filled with liquid, and the liquid pressure bulges the pipe into the desired shape. This method is often used for bellows production.
