Computes internal-pressure cylindrical-shell wall thickness per GB 150, including corrosion allowance and material negative tolerance.
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Wall thickness | t = PD/(2[σ]φ − P) | GB/T 150.1-2011 |
| Corrosion allowance | C2 = 1–6 mm by service | GB/T 150.1-2011 §4 |
| Joint efficiency | φ = 0.6–1.0 by NDT extent | GB/T 150.1-2011 |
| Allowable stress | [σ] from tensile/yield limits | GB/T 150.2-2011 |
| Hydrostatic test | PT = 1.25P hydrostatic test | GB/T 150.4-2011 |
| Minimum thickness | Minimum for stiffness by DN | GB/T 150.1-2011 §4.3 |
压力容器壁厚计算器依据 GB/T 150-2011 标准,根据设计压力、内径、材料许用应力和焊缝系数计算内压圆筒的计算壁厚、设计壁厚和名义壁厚,同时输出最大允许工作压力(MAWP)和应力利用率。
