Concentric Reducer ASME B16.9

Stainless Steel Concentric Reducer is manufactured according to ASME B16.9, American standard for buttweld pipe fittings.

Stainless steel buttweld fittings is known for the high strength, excellent corrosion withstand and long service life. They are suit for air, water, oil and natural gas applications. Schedule of buttweld fittings refers to the wall thickness, higher schedule pipe fittings can bear higher pressure. Sch 10s, Sch 40 and Sch 80 pipe reducer is more common.

Zizi is manufacture, exporter of ASME butt weld pipe fittings, we have stainless steel 316 reducers in stocks and offers 5” x 3” Sch10S Concentric reducer A403 WP316 for Singapore with best price.

Pipe Reducer Catalogue

Stainless Steel pipe reducer can be divided into concentric reducer and eccentric reducer.

Concentric reducer is symmetrical, the center of two end are on the same line, while eccentric reducer is not symmetrical and usually used in the vertical pipeline.

According to the manufacturer technique, it also divided into seamless reducer and welded reducer. Large diameter reducer often is welded in order to save cost.

Based on their materials, there are stainless steel reducer, carbon steel reducer or alloy steel reducer.
