Slice straight elbow

Slice straight elbow

The processing methods of stainless steel elbows are generally mechanical processing, such as: stamping, forging, roller processing, rolling, stretching, bending, and combination processing method.The processing method of stainless steel elbow is a combination of machining and metal pressure processing in a strict sense.Stainless steel elbow than push elbow processing is actually more than two processes: one is flaw detection, the other is heat treatment.The diameter of pipe fittings is larger than the inner diameter of pipes of the same specification. In the system, the fluid resistance is relatively small because there is no carbon steel elbow and there is a mechanical connection mode of partial diameter reduction.The three commonly used processing and forming methods of stainless steel elbow are extension method, stamping method and roller method.

The following is an introduction to the processing method of various mechanical large straight seam elbow: Roller method: the core is placed in the tube, and the outer circumference is pushed by the roller, which is used for processing the circular edge;Rolling method: generally do not use mandrel, suitable for thick wall tube inner circular edge;Stamping method: in the punching with a taper core will expand the tube end to the required size and shape;Blowing method: the rubber is placed in the tube, and the top is compressed with a punch to make the tube protrude into shape. Hydraulic bulging is formed by filling the middle of the tube with a liquid, and using the pressure of the liquid to make the tube into the desired shape.
