According to the different varieties and requirements of pipe fittings, forging pipe fittings are mainly carried out by die forging, free forging and cutting forming processes. The general die forging method has large flash and consumes materials. In order to reduce material consumption, some pipe fittings manufacturers have begun to use flash-free forming processes, which have achieved good results. This section mainly introduces the process of die forging, free forging and machining to manufacture pipe fittings.
① Die forging
For socket-welded and threaded tee, cross, elbow and other small-sized pipe fittings, the shape is relatively complex and should be manufactured by die forging.
The blanks used for die forging should be rolled profiles such as bars, thick-walled tubes or plates. When using steel ingots as raw materials, the steel ingots should be rolled into bars in advance or used as blanks after forging to eliminate segregation, porosity and other defects in the steel ingots.
After the blank is heated, it is put into the die for forging (depending on the situation, it may be forged after initial forging), and the pressure causes the metal to flow and fill the die cavity; if the blank after die forging has flash, it must be punched The step of removing the flash and remaining material, so as to complete all the die forging work.
② Free forging
Pipe fittings with special shapes or pipe fittings that are not suitable for die forging can be manufactured by free forging process. For free forging, the general shape of the pipe fittings should be forged; such as tee, the branch pipe should be forged.
③ Cutting
For some tubular shaped pipe fittings, it can be directly cut and formed by bar or thick-walled pipe, such as double socket pipe hoop, union and so on. During processing, the fiber flow direction of the metal material should be roughly parallel to the axial direction of the pipe. For tees, crosses, elbows and pipe fittings, direct cutting of bars shall not be used.
