π What It Is:
An MS R/S Eccentric S/L-40 refers to a Mild Steel (MS) Eccentric Reducer, made from Schedule 40 pipe, with the term R/S likely indicating Reducing Size, and S/L referring to Seamless/Long or Standard Length, depending on the supplier’s terminology.
An Eccentric Reducer is a pipe fitting used to join two pipes of different diameters while offsetting the centerline, unlike a concentric reducer. This prevents air pockets and ensures smooth fluid flow, especially in horizontal pipelines.
π Breakdown of Terms:
MS (Mild Steel):
A carbon steel with low carbon content; widely used for general-purpose piping due to its strength and affordability.
R/S (Reducing Size):
Indicates itβs a reducer that transitions between different pipe sizes.
Eccentric:
The centerlines of the inlet and outlet are offset. Commonly used where complete drainage or air pocket prevention is important.
S/L-40 (Schedule 40):
Denotes the pipe wall thickness as per ASME B36.10 β medium wall thickness, suitable for moderate pressure.
Large End: 1" to 24" NB
Small End: As required
