The wall thickness of Schedule 40 pipe follows the ASME B36.10/B36.19 standard and varies according to the nominal pipe diameter.
Wall Thickness Of Schedule 40 Pipe
Schedule 40 refers to the medium wall thickness standard, not a specific value, but a range of wall thicknesses. For example, the wall thickness of a Schedule 40 pipe with a nominal diameter of 1 inch is 0.133 inches, and the wall thickness of a Schedule 40 pipe with a nominal diameter of 8 inches can reach 0.322 inches. The wall thickness standards of Schedule 40 pipes of different materials are consistent, but the pressure bearing capacity varies significantly.
