General process flow of socket weld pipe fitting

　　Forging is one of the two main parts of forging. It is a kind of processing method that uses socket weld pipe fitting machinery to exert pressure on metal blank to produce plastic deformation to obtain socket weld pipe fitting with certain mechanical properties, certain shape and size. Through forging, the defects of loose as cast metal produced in smelting process can be eliminated, and the microstructure can be optimized. At the same time, the mechanical properties of forgings are generally better than those of castings of the same material because of the intact metal streamline.

　　For the important parts with high load and severe working conditions in the related machinery, except for the simple shape of rolled plates, profiles or weldments, Forged Steel High Pressure Socket Weld Pipe Fitting 45 degree elbow are often used.

　　Different forging methods have different processes, among which hot die socket weld pipe fitting process is the longest, and the general sequence is: socket weld pipe fitting blank blanking; forging blank heating; roll forging blank preparation; die forging; trimming; punching; correction; intermediate inspection, inspection of socket weld pipe fitting size and surface defects; forging heat treatment, to eliminate forging stress and improve metal cutting performance; cleaning, mainly to remove surface oxygen Generally, forgings shall be subject to appearance and hardness inspection, and important socket weld pipe fitting shall be subject to chemical composition analysis, mechanical property, residual stress and other inspection and NDT.
