Weight formula and other alloys
Weight per foot = (OD − wall) × wall × 10.68. Weights in the chart are for stainless steel. To estimate the weight of another alloy, multiply by its factor:
| Alloy | Factor |
|---|---|
| Carbon steel | 0.993 |
| Alloy 600 | 1.074 |
| Alloy 800 | 1.025 |
| Hastelloy C276 | 1.129 |
| Duplex 2205 | 0.997 |
