No6600 Alloy Concentric Reducer Chemical Pipeline Connection Project Pipe Fittings

The size head (reducing pipe) is a pipe fitting used for the diameter of the pipe. The commonly used forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming can also be used for reducing diameter pipes of certain specifications.
Diameter reduction/expansion forming
The diameter reduction forming process of the small and small heads is to put a tube blank with the same diameter as the large end of the small and small heads into a forming die, and press the tube in the axial direction to make the metal move along the mold cavity and shrink into shape. According to the size of the reducing diameter of the reducer, it is divided into one-time press forming or multiple press forming.
Stamping
In addition to the use of steel pipes as raw materials for the production of small and small heads, some specifications of the small and small heads can also be produced by stamping and forming with steel plates. The shape of the die used for drawing is designed with reference to the size of the inner surface of the size head, and the blanked steel plate is punched and stretched with the die.
Before bonding the small and small heads, wipe the socket side and the outside of the socket with a dry cloth. When there is oil 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 (Ф12.7-Ф152.4);
2. International industrial standards: DIN, ISO, SMS, 3A, IDF, etc.;
3. Product material: stainless steel 304, 316, 316L;
4. Quality and use: The inside and outside of the small and small heads are treated with *** 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 according to user requirements with drawings and samples;
6. Connection method: clamp (quick installation) type, welding type, thread (live connection) type.
Note that the size head is also suitable for pipe diameter reduction in the environmental protection and dust removal industry. Generally, they are made of steel coiled cutting and welding. The pipe diameters vary.
Generally hot-rolled coils are used very well and can save costs.
