Nickel Alloy Weight Calculator (Monel, Inconel, Incoloy, Hastelloy) Round Pipe weight calculation formula
1. Stainless Steel Round Pipe
Formula: (outer diameter – wall thickness) × wall thickness (mm) × length (m) × 0.02491
E.g.: 114mm (outer diameter) × 4mm (wall thickness) × 6m (length)
Calculation: (114-4) × 4 × 6 × 0.02491 = 83.70 (kg)
* For 316, 316L, 310S, 309S, etc., coefficient / ratio=0.02507

2. Stainless Steel Round Pipe other weight calculation formula:
Formula: (outer diameter squared– inner diameter squared) × length (m) × 0.25*π
E.g.: 114mm (outer diameter) × 4mm (wall thickness) × 6m (length)
Calculation: (114*114-106*106) × 6 × 0.00793 = 83.74 (kg)
* For 316, 316L, 310S, 309S, etc., coefficient / ratio=0.00793
Two different calculation methods can get similar results，However, the corresponding reference coefficients are different and need to be reminded
The density of stainless steel is about 7.93 g/cm3 (0.286 lb/in3). The weight of stainless steel per cubic inch is 0.286 pound, per cubic foot is 495 pounds.
