🔎 What It Is:
MS Elbow S/L-40 is a Mild Steel pipe elbow used to change the direction of flow in pipelines. The “S/L” indicates Short Radius (SR) or Long Radius (LR), and “40” refers to Schedule 40 wall thickness—commonly used for low to medium pressure applications. These elbows are either seamless or ERW welded and are ideal for general utility piping.
