Line Pipe Wall Thickness Chart
Line Pipe Wall Thickness Chart
Below is an organized line pipe wall thickness chart based on Nominal Wall Thickness and Welded Steel Line Pipe. All NPS, O.D., I.D. and Schedule are listed in inches.
We carry multiple schedules of line pipe to include, STD, Schedule 40, Schedule 80, and most intermediate line pipe wall thicknesses. We also offer CW, ERW, SMLS and DSAW line pipe.
