  • 产品详情

A stainless steel concentric reducer is a type of pipe fitting that is used to connect pipes of different sizes in a piping system. It is a conical shaped fitting that narrows down the diameter of a pipe while maintaining the centerline of the pipe. The reducer has a large end and a smaller end, and it is used to join pipes of different sizes by welding or threading. Stainless steel concentric reducers are commonly used in industrial piping systems where it is necessary to reduce the flow of fluid or gas. They are made of high-quality stainless steel, which makes them resistant to corrosion and suitable for use in high-pressure and high-temperature applications. The concentric design of the reducer ensures that there is no turbulence in the fluid flow, which helps to maintain the overall efficiency of the piping system.

对焊偏心变径管的大致重量是根据其主管长度、主管尺寸、支管尺寸、支管长度、主管壁厚和支管壁厚计算得出的。 请注意，特定制造商生产的三通实际重量可能会因制造工艺的不同而有所差异。ASME B16.9等尺寸标准并未提供对焊管件的重量数据。.

根据 ASME B16.9 标准，对焊偏心变径管的重量按以下公式计算：

0.02466 * S * H / 1000

W = 重量（千克）

OD1 = 大尺寸外径（毫米）

OD2 = 较小外径（毫米）

t = 壁厚（毫米）

H = 端到端尺寸（毫米）

What is the use of Buttweld Concentric Reducer?

  • They are helpful in services wherever cavitation is present.
  • When transporting between flanges or pipes of various ratings and wear protection is important, concentrical reducers are ideal.
  • Concentric reducers are utilized in discharge of the pump.
  • Concentric reducers can transition graciously between the piping and also the pump.
  • The concentrical reducers facilitate in transporting slurries or abrasive liquids.
