Carbon Steel Concentric Reducer
What is Buttweld Pipe Reducer?
Steel pipe reducer is used in piping system to change the diameter of pipe. ANSI / ASME B16.9 Butt weld pipe reducer is an pipe connector or pipe joint that reduces the size of pipe from larger diameter to smaller. The reduction in size is mainly equal to the average smaller and larger pipe diameter. It comes in two types that 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.
Carbon steel pipe reducer is one type of buttweld fittings in material grades ASTM A234 WPB, A860 WPHY 65 and A420 WPL6 for low temperature service. Pipe reducer has one connection method that BW only.
The concentric reducer is made with both inlet and outlet on a common center line. Compare with eccentric type, it is less costly to manufacture adaptable to most piping installations.

APPLICATIONS OF STEEL PIPE REDUCER
The usage of a steel reducer is carried out in the chemical factories and power plants. It makes the piping system reliable and compact. It safeguards the piping system from any kind of adverse impact or thermal deformation. When it is on the pressure circle, it prevents from any type of leakage and is easy to install. The nickel or chrome coated reducers extends the product life, useful for high vapor lines, and prevents corrosion.
REDUCER TYPES
Concentric reducers are widely used while eccentric reducers are applied to maintain the top and bottom pipe level. Eccentric Reducers also avoids trapping of air inside the pipe, and Concentric Reducer removes noise pollution.
