AM Cotherm

One of India’s largest Manufacturers Of ANSI B16.9 Buttweld Concentric Reducer In India, Carbon Steel Eccentric Reducer Dimensions In MM.


A reducer is a fitting that connects pipes of different size to form a piping system. Manufacturers produce the ASME B16.9 Reducer using overall dimensions, tolerances, ratings, testing, along with markings for use across several industries. A Carbon Steel Eccentric Reducer Fitting is fitting is used where the diameter of the pipe is on the upstream side of the fitting. Which means that eccentric reducers are used in instances where the flow coming from is from a larger as compared to the downstream side. Unlike a Buttweld Concentric Reducer, which resembles a cone, an eccentric reducer is known to have an edge that is shaped in a manner such that it is parallel to the connecting pipe. This parallel edge present on the eccentric reducer is what results in the two pipes having offset centre lines.

What is ASME B16.9 Reducer?


A Schedule 80 Eccentric Pipe Reducer is to be used at the suction side of pumps, which in turn will ensure that air does not accumulate in the pipe. The subtle accumulation of air in a concentric reducer could result in a large bubble. The formation of a large bubble in the ASME B16.9 concentric reducer fitting is what could eventually cause the pump to stall or it could cause cavitation when drawn into the pump. Stainless Steel Concentric Reducer Dimensions are useful when there is a shift in diameter between pipes as well as in the presence of cavitation. Unlike eccentric reducer fittings, an ANSI B16.9 Buttweld Concentric Reducer will have a common centre line.
