Calculated with density 7.93 g/cm³ for SS 304. For SS 316 (7.98) the weights are about 0.6% higher. Mill weights can vary slightly with tolerances.

SS Pipe Weight Formula

Weight (kg/m) = (OD − t) × t × 0.0249

This is π × 7.93 ÷ 1000 = 0.0249 for SS 304. For SS 316 use 0.02507. OD and t are in mm.

Example: 1 inch Sch 10S SS 304 pipe (OD 33.4 mm, 2.77 mm wall): (33.4 − 2.77) × 2.77 × 0.0249 = 2.11 kg/m.

Frequently Asked Questions

How do I calculate SS pipe weight?

Use (OD − t) × t × 0.0249 for SS 304, with OD and wall thickness in mm. The result is kg per meter.

What is the weight of a 1 inch SS pipe?

A 1 inch SS 304 pipe weighs about 1.31 kg/m in Sch 5S, 2.11 kg/m in Sch 10S and 2.53 kg/m in Sch 40S.

What is the weight of a 2 inch SS pipe?

A 2 inch SS 304 pipe weighs about 3.97 kg/m in Sch 10S and 5.50 kg/m in Sch 40S.

Is SS pipe heavier than MS pipe?

Slightly. SS 304 has a density of 7.93 against 7.85 for mild steel, so the same size is about 1% heavier.

What is the difference between SS 304 and SS 316 pipe weight?

SS 316 is a little denser (7.98 vs 7.93), so it weighs about 0.6% more for the same size.
