  • Detall del producte

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.

Butt Welding Concentric Reducer Weight Calculator

Approximate weight of a Butt welding Eccentric Reducer are calculated supported its header length, header size, branch size, branch length, header wall thickness and branch wall thickness. Please note that actual weight of a tee from a particular manufacturer might vary counting on manufacturing methodology. Dimensional standards like ASME B16.9 do not supply weights of butt attachment fittings.

Weight of a Butt Weld Eccentric Reducer as per ASME B16.9 is calculated as per following formula :

0.02466 * S <(D+d)/2 – S> * H / 1000

W = Weight in Kg

OD1 = Large Size Outside Diameter (mm)

OD2 = Smaller Size Outside Diameter (mm)

t = Wall Thickness (mm)

H = End to End Dimension (mm)

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.
