Steel Pipe Weight Calculator estimates weight of carbon steel pipe. Formula: Weight = (π/4) × (OD² - ID²) × Length × Density (490 lbs/ft³).

Formula

Weight = (π/4) × (OD² − ID²) × Length × Density
  • Carbon steel: 490 lbs/ft³; Stainless: 499 lbs/ft³; PVC: 62.4 lbs/ft³
  • Calculation assumes uniform material throughout
  • Add 5-10% for fittings, joints, and supports

2in OD × 1.5in ID × 10ft

Inputs
  • Outer Diameter (OD): 2 in
  • Inner Diameter (ID): 1.5 in
  • Pipe Length: 10 ft
  • Material: steel

Area = π/4 × (4−2.25) = 2.75 sq in; Weight ≈ 191 lbs

Frequently asked questions

What is OD and ID?
OD = Outer Diameter; ID = Inner Diameter. Wall thickness = (OD − ID) / 2
How accurate is this?
Good estimate for regular pipes; actual weight varies with mill tolerances
Can I calculate wall thickness?
Yes: Wall thickness = (OD − ID) / 2
