Manufacturing technology of carbon steel pipe fitting reducer

　　Reducer is a kind of pipe fitting used for pipe diameter. The commonly used forming process is reduced diameter pressing, expanded diameter pressing or reduced diameter plus expanded diameter pressing. Stamping can also be used for reducing pipes of some specifications.

　　a. Reducing / expanding forming

　　The reducing forming process of reducing pipe is to put the pipe blank with the same diameter as the large end of reducing pipe into the forming die, and press along the axial direction of the pipe blank to make the metal move along the die cavity and shrink. According to the size of reducing pipe, it can be divided into one-time pressing forming or multiple pressing forming.

　　b. Stamping forming

　　In addition to using steel pipe as raw material to produce pipe fitting reducer, some specifications of pipe fitting reducer can also be produced by steel plate stamping process. The shape of the die used for drawing refers to the size design of the inner surface of the pipe fitting reducer, and the blanking steel plate is stamped and stretched by the die.

　　Before the pipe fitting reducer is bonded, wipe the socket side and the outside of the socket with a dry cloth. When there is oil stain on the surface, wipe it with acetone. Pay attention to the following points:

　　1. Control caliber: DIN standard (dn10-dn150), 3A / IDF standard (1 / 2 "- 6"), ISO standard（ Ф 12.7- Ф 152.4)；

　　2. International Industrial Standards: DIN, ISO, SMS, 3a, IDF, etc;

　　3. Product material: stainless steel 304, 316, 316L;

　　4. Quality and application: the inside and outside of the pipe fitting reducer are treated with high-grade polishing equipment to meet the requirements of surface precision; This product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;

　　5. External processing: you can process non-standard products with drawings and samples according to user requirements;

　　6. Connection mode: clamp type, welding type and thread type.

　　Note that the pipe fitting reducer is also suitable for pipe reducing in the environmental protection and dust removal industry. It is generally made of rolled steel plate, cut and welded, with different pipe diameters and different materials

　　It is generally hot-rolled coil, which is applied very well and can save cost.
