How the weight is calculated
Weight per foot = 10.69 × (OD − t) × t = 10.69 × (5.563 − 0.258) × 0.258 = 14.63 lb/ft.
The factor 10.69 is the density of carbon steel (0.2836 lb/in³) × π × 12 in/ft.
Frequently asked questions
How much does 5" Schedule 40 pipe weigh?
5" Sch 40 pipe weighs 14.63 lb/ft (21.78 kg/m). A 21 ft random length weighs about 307 lb and a 6 m length about 130.7 kg.
What is the outside diameter of 5" pipe?
5.563 in (141.3 mm). The outside diameter is the same for every schedule; a higher schedule means a thicker wall and a smaller inside diameter.
How much does 5" Schedule 40 pipe weigh full of water?
23.30 lb/ft: 14.63 lb/ft of steel plus 8.67 lb/ft of water (34.69 kg/m in total). Use this for pipe support and hanger loads.
What is the inside diameter of 5" Schedule 40 pipe?
5.047 in (128.2 mm), from OD − 2 × wall = 5.563 − 2 × 0.258.
