Reducer pipe is also known as size head. It is one of the chemical pipe fittings used to connect two pipes of different diameters. Titanium reducer is divided into concentric size heads and eccentric size heads.
Standards: national standards, American standards, British standards, and various non-standard high-pressure stamping.
The quality of the Titanium reducer should align with the current national standards "steel butt-welded seamless pipe fittings" GB / T 12459-2005 and "steel butt-welded pipe fittings" GB / T13401-2005. the roundness of the reducer should not be greater than 1% of the corresponding end OD, and the allowable deviation is ±3%. The permissible deviation is ±3mm; the permissible deviation of the reducer size should be by the requirements of Table 4.2.2-3.
Seamless pipe reducer production
A Reducer (big head and small head) is used for pipeline reducer at a pipe fitting. Commonly used molding process is to reduce the size of the press, expand the size of the press, or reduce and expand the size of the press, press molding can also be used to reduce the diameter of some specifications.
1、Reduction/expansion molding
The Reduction forming process is to reduce the diameter of the pipe and the large end of the pipe with the same diameter billet into the forming die, and along the billet axial extrusion to move the metal along the cavity and contraction Forming. Depending on the size of the reduced diameter of the reducer, it can be divided into one-press molding or multiple-press molding.
In the process of shrinking or expanding deformation, cold pressing or hot pressing is determined according to the different materials and the situation of reducing diameter. Normally, cold pressing should be used as far as possible, but due to multiple reductions, wall thickness, or alloy steel materials caused by severe work hardening, hot pressing should be used.
2、 Stamping and forming
In addition to the use of steel pipe as the raw material for the production of reducers, certain specifications of reducers can also be produced by stamping and molding of steel plates. The shape of the mold used for deep drawing is designed according to the dimensions of the inside surface of the reducer, and the punched steel plate is punched and drawn with the mold.
Among them, steel pipe fittings include Titanium reducers, tees, crosses, flanges, elbows, and other products. The materials of the products are carbon steel, stainless steel, alloy steel, and other metal materials that users have special requirements. The company adopts scientific production technology, strict quality management, advanced service concept, and reasonable prices.
