A reducer (or reducing pipe) is a pipe fitting used to connect pipes of different diameters. The commonly employed forming processes include diameter-reducing restriction, diameter-expanding restriction, or a combination of both—diameter-reducing and diameter-expanding restrictions. For certain standard reducers, stamping can also be used for forming. In the diameter-reducing/diameter-expanding forming process for reducers, a tube blank with a diameter equal to that of the larger end of the reducer is placed into a forming die.

For certain standard reducers, stamping can also be used for forming. In the diameter-reducing/diameter-expanding forming process for reducers, a pipe blank with a diameter equal to that of the larger end of the reducer is placed into a forming die.

By restricting the metal along the axial direction of the tube blank, the metal is forced to flow into the die cavity and undergoes contraction and shaping. Depending on the degree of diameter change in the reducer pipe, the forming process can be classified as either single-stage restriction forming or multi-stage restriction forming. In addition to using steel pipes as raw material for producing reducers, stamping can also be employed to manufacture certain standard-sized reducers from steel plates.
The shape of the die used for stretching is designed according to the dimensions of the inner and outer surfaces of the large and small heads. The steel plate, after being cut to size, is then stamped and stretched into shape using this die. Before bonding the large and small heads together, use a dry cloth to clean both the socket side and the outside of the spigot. If there is oil or grease on the surface, wipe it clean with acetone. The following points should be noted:
Connection Size: DIN standard (DN10–DN150), 3A/IDF standard (1/2"–6"), ISO standard (Φ12.7–Φ152.4); International industrial standards: DIN, ISO, SMS, 3A, IDF, and others; Material: Stainless steels 304, 316, and 316L; Quality and Application: Both the inner and outer surfaces of the reducer are treated with high-grade polishing equipment to meet stringent surface finish requirements. This product is suitable for industries including dairy, food, beer, beverages, pharmaceuticals, cosmetics, and more.
