Special pipe fitting Reducer reduction molding of processing technology

　　Special pipe fitting reducer the appearance shall be free of cracks and double skin, and the wall thickness shall be greater than the wall thickness of the large-diameter end pipe section. The roundness of eccentric special pipe fitting reducer shall not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation shall be ± 3mm; the center lines of both ends of concentric special pipe fitting reducer shall coincide, and the allowable deviation of the eccentric value shall be ± 5mm.

　　The reducing forming process of a is to put the tube blank with the same diameter as the large end of a into the forming die. By pressing along the axial direction of the tube blank, the metal moves along the die cavity and shrinks to form A234 WPB Carbon Steel Threaded Eccentric Special Pipe Fitting Reducer the appearance shall be free of cracks and double skin, and the wall thickness shall be greater than the wall thickness of the large-diameter end pipe section. The center lines at both ends of concentric special pipe fitting reducer shall coincide, and the allowable deviation of the eccentricity value shall be ± 5mm. According to the size of a reducer, it can be divided into one-time pressing forming or multiple pressing forming.

　　As like as two peas, the die is guaranteed to have the size and shape accuracy, and the surface quality of stamping parts is not destroyed. The life of dies is generally longer. So the quality of stamping is not disturbed, and the interchangeability is good.

　　Generally, stamping is not made of chips and chips, so the consumption of materials is less, and no other heating equipment is needed, so it is a material saving and energy-saving processing method, and the cost of stamping parts is lower
