Seamless elbow factory
Seamless elbow is a kind of pipe fitting used for pipe turning. In the pipe system of the total use of pipe fittings, accounting for a large proportion of about 80%. Generally, different forming processes are selected for elbows with different material wall thickness. At present. Manufacturers commonly used seamless elbow forming process has hot push, stamping, extrusion and so on
Forging method: the end of the pipe or part of the forging machine to stretch, so that the outer diameter is reduced, commonly used type forging machine has rotary, connecting rod type, roller type.
Rolling method: generally without mandrel, it is suitable for the inner circular edge of thick wall pipe. The core is placed in the tube, and the roller is used to push and press the outer edge.
Stamping: expansion of tube ends to desired size and shape with tapered cores in a punch press.
Bending forming method: there are three methods more commonly used, one method is called stretching method, another method is called stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjustment roller, adjust the fixed roller distance, the finished pipe is bending.
Bulge method: one is to place rubber in the tube, above the punch compression, so that the tube protruding shape; Another method is hydraulic bulging, in which a liquid is filled in the middle of the pipe and the pressure of the liquid bulges the pipe into the desired shape. This method is used in most bellows.
Seamless elbow is a kind of material commonly used in elbow, cheap and easy to use. According to the material is divided into: low carbon steel, medium carbon steel, high carbon steel,20 steel (20g), Q235A, Q235B, etc., is characterized by relatively high carbon content. According to the standard is divided into: Gb, NON-STANDARD, German standard, Japanese standard, American standard, British standard elbow. The raw material of seamless elbow is seamless steel tube. The main production process is round tube billet → heating → perforation → three-roll cross rolling, continuous rolling or extrusion → tube stripping → sizing (or reducing) → cooling → straightening → water pressure test (or defect detection) → marking → storage.
