Reducer concentric reducer 2205 material reducer dual phase steel 2205 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
Reducing / expanding forming
The diameter reduction forming process of large and small head is to put the tube blank with the same diameter as the large end of large and small head into the forming die, and press along the axial direction of the tube blank to make the metal move and shrink along the die cavity
According to the size of reducing pipe, it can be divided into one-time pressing forming or multiple pressing forming

Stamping forming
In addition to using steel pipe as raw material to produce large and small heads, large and small heads of some specifications can also be produced by steel plate stamping process
The shape of the die used for drawing is designed according to the size of the inner surface of the large and small head, and the blanking steel plate is stamped and stretched by the die

Before bonding the big and small ends, 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 a dry cloth
Pay attention to the following points:
1
Control caliber: DIN standard (dn10-dn150), 3A / IDF standard (1 / 2 & quot; - 6 & quot;) 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 big and small head 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: non-standard products can be processed with drawings and samples according to user requirements;
6
Connection mode: clamp (quick assembly), welding and thread (Union)

Note that the large and small ends are also suitable for pipe reducing in the environmental protection and dust removal industry
They are 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
