Steel Pipe Reducer ASME B16.11 SS Concentric Reducer , A-304304L, 316316L,6 4 lnch 3000#,Cold Drawn

Diameter pipe reducer also known as size head, diametral pipe, diametral through. One of the chemical pipe fittings for the connection between two different pipe diameters. According to the shape of different, divided into concentric size head and eccentric size head two kinds. The size head material includes stainless steel size head (304304 l316316l), alloy steel, carbon steel size head, size head material has 20 steel, Q235,Q345,16Mn and so on.

Making seamless head
Size head (diameters) is a kind of pipe fittings for pipe caliber. The forming process usually used is shrinkage pressing, expansion pressing or expansion pressing, and stamping can also be used for some specifications of diameters.
Shrinkage/diameter Expansion Forming
The shrinkage forming process of the size head is to put the tube billet equal to the diameter of the large end of the size head into the forming die, and by pressing along the axial direction of the tube billet, the metal moves along the die cavity and shrinks to form. According to the size of diameters, it can be divided into one pressing forming or multiple pressing forming.
Stamping forming
In addition to the use of steel pipe as raw material to produce the size of the head, part of the size of the head can also be produced by stamping forming process. The shape of the die used for drawing is designed according to the size of the innersurface of the head, and the steel plate after blanking is punched and stretched with the die.
Before the size head is glued, the socket side and the outside of the socket are wiped with dry cloth. When the surface is greasy, it should be wiped with acetone. The following points should be noted:
1. control calibre: DIN (DN10-DN150),3A/IFF (1/2"-6"), ISO (Ф12.7-Ф152.4);) Standards
2. International Industrial Standards: DIN,ISO,SMS,3A,IDF;
3. material: stainless steel 304,316,316 L;
4. quality and use: high-grade polishing equipment inside and outside the head to meet the surface precision requirements; this product is suitable for dairy, food, beer, beverage, pharmaceutical, cosmetics and other industrial fields;
5. external processing: according to user requirements to map, sample processing non-standard products;
6. connection: Clamp (quick) type, welding type, thread (live) type.
Note that the size of the head is also suitable for environmental protection dust removal industry pipe diameter, generally made of steel coil cutting and welding, pipe diameter is different, material
Generally hot rolled coil, the application is very good, can save costs.
