Schedule 80 pipe weight refers to the theoretical weight of Schedule 80 steel pipe per unit length, usually expressed as kg/m or lb/ft.
Schedule 80 pipe is classified as medium-pressure piping; it features a thicker wall than standard pipe, resulting in a heavier weight compared to pipes of the same outside diameter. The table below lists the weights of common pipe sizes for reference purposes.
