Product Description

Reducer, also known as the size of the head is one of the chemical fittings, used for the connection of two different pipe diameters. It is also divided into concentric size head and eccentric size head. Reducer materials include stainless steel reducer, alloy steel, reducer carbon steel head, reducer 20 steel q234q345 and so on.
The roundness of the reducer should not be greater than 1% of the corresponding end of the outside diameter, and the permissible deviation is ± 3mm. the material of the reducer to implement the SY/T5037, GB/T9711, GB/T8163, American Standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234, ASTM A106, DIN German standard and customer requirements standards.
Reducer (size head) is a kind of pipe fittings used in pipe reducer. Usually the molding process for the reduction of pressing, expansion of pressing or reduction and expansion of pressing, for some specifications of the reducer can also be used for stamping molding.
Eccentric reducer English is used for pipeline reducer at a pipe fitting, usually using the molding process for reducing the size of the press, expanding the size of the press or reduce the size of the press or expanding the size of the press, for some specifications of the reducer can also be used for stamping.
Eccentric reducer in addition to the use of steel pipe as raw material for the production of reducers, for some specifications of the reducer can also be used in steel plate stamping molding process for production. The shape of the die used for stretching is designed with reference to the inner surface size of the reducer, and the steel plate is stamped and stretched with the die.
Mainly used in:
1、When the flow of fluid in the pipeline changes, such as increasing or decreasing, the flow rate requirements do not change, are required to use the reducer.
2, in the pump inlet, in order to prevent cavitation, the need to use reducer.
3, and instrumentation, such as flow meters, control valve joints, in order to cooperate with the instrumentation joints, also need to use the reducer.
