Schedules with an S suffix (5S, 10S, 40S, 80S) are stainless steel pipe per ASME B36.19M; weights shown are for carbon steel, so multiply by about 1.01 for stainless steel.
Weight filled with water and flow area
For supports and hangers, add the weight of the contents. Water weighs 62.4 lb/ft³ (1000 kg/m³).

How the weight is calculated
Weight per foot = 10.69 × (OD − t) × t = 10.69 × (22 − 0.375) × 0.375 = 86.69 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 22" Schedule 40 pipe weigh?
22" Sch STD pipe weighs 86.69 lb/ft (129.03 kg/m). A 21 ft random length weighs about 1,820 lb and a 6 m length about 774.2 kg.
What is the outside diameter of 22" pipe?
22 in (558.8 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 22" Schedule 40 pipe weigh full of water?
240.44 lb/ft: 86.69 lb/ft of steel plus 153.75 lb/ft of water (357.85 kg/m in total). Use this for pipe support and hanger loads.
What is the inside diameter of 22" Schedule 40 pipe?
21.250 in (539.8 mm), from OD − 2 × wall = 22 − 2 × 0.375.
