Eccentric reducer
Eccentric reducer refers to small or large heads whose centers are not on the same straight line. Its role is to stick the wall or stick the ground to go pipeline without occupying space, and is connected to two
reducer
One of the chemical pipe fittings used for connecting two pipes of different diameters. Divided into concentric size head and eccentric size head. See pipe fitting.
Reducing pipe material includes stainless steel reducing pipe, alloy steel, reducing pipe carbon steel size head, reducing pipe 20 steel Q234Q345 and so on.

Production methods
The roundness of the reducing tube should not be greater than 1% of the outer diameter of the corresponding end, and the allowable deviation is ±3mm. The material of reducing pipe is SY/T5037, GB/T9711, GB/T8163, ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standards and customer requirements
Reducing pipe (size head) is a piece of pipe used in reducing pipe diameter. The forming process is usually used for reducing the diameter pressing, expanding pressing or reducing the diameter and expanding pressing, for some specifications of reducing pipe can also use stamping forming.
