Seamless reducer

The seamless reducer is directly butt welded to the steel pipe. The main manufacturing standards for concentric reducers are GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, SY/T0510. Corresponding to the concentric reducer is the eccentric reducer, which is made of carbon steel, alloy steel and stainless steel

Seamless reducer is made by directly butt welding reducer and steel pipe, hot pressing or forging. Classification: pushing, pressing, forging and casting. Corresponding to the concentric reducer is the eccentric reducer, which is made of carbon steel, alloy steel and stainless steel

The seamless reducer is generally used for connection. For example, the concentric reducer at the outlet of centrifugal pump is used to connect the pipeline with the inlet and outlet of the pump. The incoming goods generally become smaller and the outlet becomes larger

The seamless reducer has the following characteristics:

1. When the flow of fluid in the pipe changes, such as increasing or decreasing, and the flow rate requires little change, the reducer shall be used

2. For incoming goods into the pump, to prevent cavitation

3. At the joints with instruments, such as flowmeters and regulating valves, reducing pipes are also required to match with the joints of instruments

Seamless reducer application: when the fluid flow in the pipeline changes, such as increasing or decreasing, and the flow rate requires little change, reducer shall be used; In order to prevent cavitation during the purchase of pumps, reducing pipes shall be used; At the joints with instruments, such as flow meters and regulating valves, reducing pipes are also required to match with the joints of instruments. At present, reducer reducer is required for most pipe networks, mainly used in petroleum, chemical industry, natural growth gas, steam pipe networks, hydraulic machinery, etc
