What Is The Production Process of Steel Reducers

Steel reducers are a type of reducing pipe fittings used at the reduced diameter of pipelines. Steel reducers are produced and manufactured by compression pressing, diameter expansion pressing, or reduction and expansion pressing. The steel reducer is The reducing forming process is to put the tube blank with the same diameter as the large end of the steel reducer into the forming mold, and by pressing the tube blank in the axial direction, the metal moves along the mold cavity and shrinks into shape. According to the steel reducer, The size of the pipe diameter reduction is divided into one-time pressing forming or multiple pressing forming. Only steel reducers with widely different specifications and models adopt multiple pressing forming. For example, the steel reducer DN400 is changed to DN273. It requires multiple pressings. Some special specifications and models of steel reducers are formed by stamping. In addition to using steel pipes as raw materials to produce steel reducers, some specifications of steel reducers can also be formed by stamping steel plates. process for production. The shape of the punch used for drawing is designed concerning the inner surface dimensions of the steel reducer, and the punch is used to punch and stretch the blanked steel plate into shape. Large-diameter steel reducers are formed by welding. Butt-welded steel reducers are formed by rolling steel plates and then welded. Many butt-welded steel reducers are produced, and butt-welded reducers of special materials are completed. Afterward, it needs to be annealed and flaw-tested to see if there are any pores in the steel reducer.

This is the production and processing technology of several reducers. The roundness of the steel reducer should not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation is ±3mm. A steel reducer is a pipe fitting used for pipe diameter reduction. The commonly used forming processes are reducing diameter pressing, expanding diameter pressing or reducing the diameter and expanding diameter pressing. Steel reducers of certain specifications can also be formed by stamping.
