Titanium Concentric Reducer

ANSI / ASME B16.9 Concentric Reducer

Manufacturer of ANSI B16.9 SS Reducer in Mumbai, India, Carbon Steel Concentric Reducer Bw Suppliers.

Titanium Concentric Reducer is a pipe fitting that is designed to connect two pipes of different diameters while maintaining a centerline or axis of the pipes. The reducer is called "concentric" because the center of the inlet and outlet ends align, forming a cone or taper.

According to the ASME B16.9 Concentric Reducer specification, the following materials can be used to manufacture reducers - , Hastelloy, Titanium, Monel, Nickel, Inconel Tantalum, Stainless Steel, Alloy Steel, Carbon Steel, Cupro-Nickel 90/10 as well as Cupro-Nickel 70/30. Our regular production schedules include Stainless Steel Concentric Reducer B16.9 of different dimensions like - Stainless Steel ASME / ASTM SA / A403 SA / A 774 WP-S, WP-W, WP-WX in different stainless steel grades such as 304, 304L, 316, 316L, 304/304L, 316/316L, DIN 1.4301, DIN1.4306, DIN 1.4401, DIN 1.4404

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.
