Stainless steel reducer is used for pipe diameter changes in a pipe. Usually adopted for reducing the forming process of pressing, expanding to suppress or reducing and expanding, to certain specifications of the reducer and stamping can be applied. One size head belong to chemical pipe fittings, for connecting the two kinds of different diameter. Is pided into concentric big small head and eccentric reducer. Size head size materials including stainless steel (304304 l316316l), alloy steel head size, carbon steel head size, size head of 20 steel q234q345 etc. Size reducing forming technology of the head is with the head big end diameter equal to the size of the pipe into the forming die, along the axial direction of tube billet by pressing, shrink along the cavity movement and metal forming. According to the size of the reducer reducer, pided into the one of pressing or more press forming.
Besides using steel as raw material to produce the size of the head, on the part of the specifications of the size of the head can also be used steel plate stamping forming technology is adopted to improve the production. Used by stretching die shape inner surface size design with reference to the size of the head, use after blanking punching die, stamping steel stretch forming.
