Schedule 40 pipe weight per foot
Schedule 40 steel pipe weight per foot and per meter for every NPS from 1/2" to 24". OD and wall from ASME B36.10M, the published weight next to ours.
Updated September 2026
Quick answer
2 inch Schedule 40 steel pipe weighs 3.65 lb per foot. 4 inch is 10.79, 6 inch is 18.97, 8 inch is 28.55, 10 inch is 40.48, and 24 inch is 171.29 lb per foot, all from the ASME B36.10M table.
Schedule 40 steel pipe weight chart
OD and wall in inches. The lb/ft column is computed from the OD and wall with mild steel at 0.2836 lb/in³, the same math as the calculator. The small number under it is the weight printed in B36.10M. kg/m is our lb/ft converted.
Dimensions per ASME B36.10M. Weight = π × (OD − wall) × wall × 0.2836 lb/in³ × 12 in/ft. Schedule 40 matches STD through 10"; from 12" up this is the Schedule 40 wall, which is heavier than STD.
Schedule 80 and XXS
Same OD, thicker wall. The full pipe weight chart has Schedule 40, 80, and XXS side by side. For a cut length or a stick count, use the steel pipe weight calculator.
Example: 200 feet of 2" Schedule 40 is 730 lb before drops.
Questions welders keep asking
How much does 2 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 2" Schedule 40 steel pipe at 3.65 lb/ft. It has a 2.375" OD and a 0.154" wall; working it out from those gives 3.66 lb/ft (5.44 kg/m). A 21-foot length weighs about 77 lb.
How much does 4 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 4" Schedule 40 steel pipe at 10.79 lb/ft. It has a 4.500" OD and a 0.237" wall; working it out from those gives 10.80 lb/ft (16.08 kg/m). A 21-foot length weighs about 227 lb.
How much does 6 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 6" Schedule 40 steel pipe at 18.97 lb/ft. It has a 6.625" OD and a 0.280" wall; working it out from those gives 18.99 lb/ft (28.27 kg/m). A 21-foot length weighs about 398 lb.
How much does 8 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 8" Schedule 40 steel pipe at 28.55 lb/ft. It has a 8.625" OD and a 0.322" wall; working it out from those gives 28.58 lb/ft (42.54 kg/m). A 21-foot length weighs about 600 lb.
How much does 10 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 10" Schedule 40 steel pipe at 40.48 lb/ft. It has a 10.750" OD and a 0.365" wall; working it out from those gives 40.53 lb/ft (60.31 kg/m). A 21-foot length weighs about 850 lb. At 10" Schedule 40 and STD are still the same wall.
How much does 24 inch schedule 40 pipe weigh per foot?
ASME B36.10M lists 24" Schedule 40 steel pipe at 171.29 lb/ft. It has a 24.000" OD and a 0.688" wall; working it out from those gives 171.48 lb/ft (255.19 kg/m). A 21-foot length weighs about 3,597 lb. At this size Schedule 40 is a much heavier wall than STD, so check which one the drawing calls for before you order.
Is Schedule 40 the same as STD pipe?
Up through 10" it is: the Schedule 40 wall and the STD (standard weight) wall are the same number. From 12" up they split and Schedule 40 is the heavier wall. This chart is the Schedule 40 wall at every size.
