🔎 What It Is:
An MS (Mild Steel) 1D Elbow S/L SCH 80 is a butt-weld pipe fitting used to change the direction of flow in piping systems. The term 1D refers to the radius of curvature being equal to the nominal diameter of the pipe, offering a sharp turn. S/L stands for Seamless, and SCH 80 (Schedule 80) indicates a heavy wall thickness for high-pressure applications.
