  • Dettagli del prodotto

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

Il peso approssimativo di un riduttore eccentrico con saldatura testa a testa è calcolato in base alla lunghezza della testata, alla dimensione della testata, alla dimensione del ramo, alla lunghezza del ramo, allo spessore della parete della testata e allo spessore della parete del ramo. Si noti che il peso effettivo di un tee di un particolare produttore può variare a seconda della metodologia di produzione. Gli standard dimensionali come ASME B16.9 non forniscono i pesi dei raccordi con attacco di testa.

Il peso di un riduttore eccentrico con saldatura testa a testa secondo ASME B16.9 è calcolato secondo la seguente formula:

0,02466 * S * H / 1000

W = Peso in Kg

OD1 = Diametro esterno di grandi dimensioni (mm)

OD2 = Diametro esterno della taglia più piccola (mm)

t = spessore della parete (mm)

H = Dimensione da estremità a estremità (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.
