The reducer is one of the chemical pipe fittings, which is used for the connection of two different pipe diameters. The forming process of the reducer is usually reducing diameter pressing, expanding diameter pressing or reducing diameter and expanding diameter pressing. The pipe can also be formed by stamping. The reducer is divided into concentric reducer and eccentric reducer. We produce reducers of different materials, such as carbon steel reducers, alloy reducers, stainless steel reducers, Low temperature steel reducer, high performance steel reducer, etc., can meet your different choices. Application : chemitry industry , oil and gas industry etc.
