ANSI / ASME B16.9 Concentric Reducer

The specification for Asme B16 9 Concentric Reducers covers fittings of any producible wall thickness. According to the ASME B16.9 specification, we manufacture reducers of various thickness or schedules such as - Schedule 5S, , S20, S30, STD ,10S, 20S, S10, 40S, S40, S60, S80, S100, XS, 80S, S120, S140, S160, XXS and etc.

What is ASME B16.9 Concentric Reducer?

The Specification for ASME B16.9 is a standard that covers Factory Made Wrought Steel Buttwelding Fittings like the Concentric Reducer Fitting. This Standard covers parameters such as the overall dimensions, ratings, tolerances, testing, and markings for both wrought carbon as well as alloy steel factory-made buttwelding fittings. The size range of the Concentric Reducer En 10253 2 covered in this specification ranges between NPS ½ inch up to 48 inches. The size range for both seamless and welded Ansi B 16.9 Concentric Reducer is different. To specify, the size range for seamless Asme B16.9 Reducer Dimensions are up to 24 inches, whereas welded Asme B16 9 Eccentric Reducer Dimensions are available in the size range between 8 inches up to 36 inches.
