Product Details

A reducer is a pipe coupling with a larger bore size at one end and a smaller bore size at the other end.It is used to change the flow rate in pipeline.Base on connection ways,there are 3 types of reducers :threaded reducer ,grooved reducer and butt welding reducer.

Generally ,the butt welded reducer is made from pipes.Put a fixed length steel pipe on a conical mould,and its shape is changed by pressing down.Reducing one end or extend one end,then a welded reducer is formed.For big size reducers or low pressure welded reducers,they are made from steel coils.Rolling up the steel plate to a reducer shape,and welding them together.

What is the difference between a concentric and eccentric reducer?

The Concentric reducer two ends are centered in a line,while the Eccentric reducer have the offset center of both ends and has an edge that is parallel to the pipe.Concentric pipe reducer is used when the pipe is vertical and eccentric reducer is ofen used when the pipes are lay on a pipe rack,because of the parallel edge,it could allow the reducer and pipe next to the walls or groud with out taking up space.
