A concentric Reducer is used to affix pipe section or tube sections on an equivalent axis. The butt weld concentric Reducer is cone like, and is used once there’s a shift in diameter between pipes. For instance, once a 1″ pipe transitions into a 3/4” pipe and also the high or bottom of the pipe does not get to stay level. This pipe concentric Reducer is also used once there’s one diameter modification or multiple diameter changes. Concentric Reducers have a typical center line. Concentric Reducers are helpful once cavitation is gift. Eccentricity happens once the center line is offset. Concentric Reducers are used for vertical piping. they supply associate in-line round shape transition between controlled pipes of differing diameters. A pipe reducer will be one diameter modification or a multiple diameters modification. The pipes cannot acknowledge what the skin configuration of the pipe reducer feels like. The pipe flow is laid low with the within diameter round shape transition configuration which might be axially moved and outwardly reconfigured to supply for additional economical reducer fittings. Thus, concentric reducers connect pipes of unequal size, however have a typical center line. In alternative words, it’s a sort of pipe fitting with completely different size ends to affix pipes of various diameters that joins pipe sections on an equivalent axis. Concentric reducers are designed with the tiny and huge diameters on opposite ends and joined by a cone a formed transition section. They’re on the market in each seamless and welded construction.

Dimensional Tolerances are in millimeters unless otherwise indicated and are equal ± except as noted.

MSS SP-43 solely covers Stainless Steel Butt Weld Fittings created to be used with Schedule 5S and 10S Concentric Reducer appropriate to be used with Schedule 40S pipe, as outlined in ASME B36.19. The scale and Dimensional Tolerances outlined in MSS SP-43 area unit considerably a similar as those in ASME B16.9 specifications from NPS 1/2 — NPS twenty-four. Except with relation to the skin diameter at the bevel.

How to take Measurements of Concentric Reducers?

Get the measurements of outer diameter (OD) and inner diameter (ID) , height (H), and the total dimension (T1, T2).

What is The Function of Concentric Reducer?

The Concentric Reducer method applies a function (Concentric Reducer) against an accumulator and each value of the array (from left-to-right) to Buttweld Reduce it to a single value. And what does a redux reducer do? The Butt Weld Concentric Reducer is a pure function that takes the current state and an action, and returns the next state.

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.

ASME B16.9 Butt Welding Concentric Reducer Weight Calculator

Approximate weight of a Butt welding Concentric 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 Concentric 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)
