Buttweld Fittings

Pipe Reducer manufacturer in India

Refer ASME B16.9 Stainless Steel Reducer Dimensions of Concentric and Eccentric

Reducers are fittings that ease the transition between a smaller pipe size to larger pipe size. One of the main flaws of these fittings is that they are very likely to experience failure when the stress levels are elevated. Tp prevent system failure, manufacturers recommend using an ANSI B16.9 Buttweld Concentric Reducer. Buttweld fittings are useful for two reasons. One is that they offer leak-proof transportation of the gas or fluid in the system and the other reason is that they have a structure that is more gradual and permits easy flow. The Stainless Steel Concentric Reducer Dimensions make it easy for the flow to move around easily without cracking. Cracks are a common feature in piping systems if incorrect material or fittings are used. Pipe Reducer produced in stainless steel or carbon steel are high performing and are amongst the inexpensive materials to be used for production. There are two types of reducers that could be used in various sectors i.e. - eccentric as well as concentric reducers. Both the concentric as well as the Schedule 80 Eccentric Pipe Reducer are conically shaped, thus they are capable of fitting between two different sized pipes and bridging their gap. The Buttweld Concentric Reducer is particularly well suited for those industries that have hydraulic requirements in their application. Reducers may also be used in pumps. The main purpose of using a Carbon Steel Eccentric Reducer Fitting is to guarantee that air is not stored in the pipe.

Concentric Reducer Type B Formula

Pipe Reducer weight formula is 0.02466 * S <(D+d)/2 – S> * H / 1000

  • d = Small end dia. in millimeter
  • D = Large end dia. in millimeter
  • S = Large end Thick. in millimeter.
  • H = Height from end to end.
