Content

The two ends of ASTM A234WPB butt weld concentric reducer fittingsare designed with large diameter and small diameter.

  • Reducer coupling for joining two concentric pipes of different sizes
  • Butt-weld, beveled openings for welding pipes together
  • Welded connections to ensure tight seals and reduce the possibility of leakage
  • Made of stainless steel 304/304L for strength and ease in welding
  • Lower carbon content to ensure greater resistance to corrosion

Product features

  • Concentric reducers will change kindly between the pump and piping.
  • Concentric reducers are tapered and are used when the diameter between pipes changes.
  • Concentric reducers provide an in-line conical transition between pressurized pipes of different diameters.
  • The length dimension of the reducer is almost equal to the average of the big bore and smaller bore pipe diameters.

Applications

  • Concentric reducers are easy to transport mud and grinding fluid and are suitable for corrosive operations
  • Concentric reducers are used to connect pipe segments or pipe segments on the same axis.
  • Concentric reducers are beneficial to use where different ratings and to wear protection is required in conveying between flangesor pipes.
  • Concentric reducers are perfectly suitable to use in the exclusion of the pump.
