| Date2026-07-21 | Rev0 | Basisin/100 ft tabulated expansion method |
Steam line with tabulated expansion 2.6 in/100 ft at operating temperature, 120 ft between anchors — the PVP Suite selftest case.
| Coefficient | 2.6 | in/100 ft |
| Length | 120 | ft |
Δ = (coefficient in/100ft) × L(ft) / 100
The coefficient is the tabulated total expansion for your material between installation and operating temperature (e.g. B31.1 Appendix B / B31.3 Appendix C tables — user-supplied). For coefficients per unit temperature, use the expansion-loop card's α·ΔT·L form instead.
