ASTM A234 WPB concentric reducers and eccentric reducers

Reducer is pipe fittings component used in piping system to change the diameter of pipe.ASME B16.9 butt welding pipe reducer is an pipe connector or pipe joint that reduces the size of pipe from larger diameter to smaller.The pipe reducer comes in two main types:concentric reducer and eccentric reducer.The concentric pipe reducer is used in vertical piping system.The eccentric pipe reducer is used in horizontal piping system.The reduction in size is mainly equal to the average smaller and larger pipe diameter.Each has different use as per their size, properties and specification.
