Reducer is one of the chemical industrial pipe fittings. It is used in connecting two pipes with different diameters. It usually adopts diameter reduction pressing, diameter expansion pressing or diameter reduction and expansion pressing. Stamping is treated in some reducers. The reducers were divided into    concentric reducer eccentric reducer. We produced reducers with different materials, such as carbon steel reducer, alloy reducer, stainless steel reducer, low temperature steel reducer and high performance steel reducer etc, which could meet your different choices.
