Structural characteristics and applications of stainless steel reducers

　　ASTM B16.9 Butt Weld Schedule 40 316L Stainless Steel Eccentric Reducer is a kind of pipe fitting used at the pipe diameter reduction. The commonly used forming process is reduction pressing, diameter expansion pressing or reduction and expansion pressing. For certain specifications of reducers, stamping can also be used. Forming.

　　In addition to using steel pipes as raw materials to produce reducers, ASTM B16.9 Butt Weld eccentric stainless steel reducers can also be produced with steel plates using the stamping forming process for some specifications of reducers. The shape of the punch used for drawing is designed with reference to the inner surface size of the reducer, and the die is used The blanked steel plate is stamped and stretched into shape.

　　Structural features

　　The ASTM B16.9 Butt Weld stainless steel eccentric reducer is made of carbon steel and is expressed as the diameter of the large head multiplied by the diameter of the small head multiplied by the thickness.

　　ASTM B16.9 Butt Weld Stainless steel eccentric reducer standards: national standard, American standard, British standard and various non-standard high-pressure stamping.

　　The reducing forming process of the ASTM B16.9 Butt Weld stainless steel eccentric reducer is to put the tube blank with the same diameter as the large end of the 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 size of the reducer can be divided into one-time press forming or multiple press forming.

　　The characteristics of ASTM B16.9 Butt Weld stainless steel eccentric reducer are that the strength is higher than that of carbon steel with the same carbon content, and it has better toughness, plasticity and good weldability.

　　application

　　1. When the flow rate of the fluid in the pipeline changes, such as increasing or decreasing, and the flow rate requirements do not change much,ASTM B16.9 Butt Weld stainless steel reducers must be used.

　　2. At the inlet of the pump, in order to prevent cavitation, a ASTM B16.9 Butt Weld stainless steel reducer needs to be used.

　　3. In order to cooperate with the joints of instruments, such as flow meters and regulating valves,ASTM B16.9 Butt Weld stainless steel reducers must also be used.
