Table 2 Oil and gas pipelines’ parameters
From: Stress analysis of parallel oil and gas steel pipelines in inclined tunnels
Pipelines | Diameter (mm) | Thickness of straight pipe (mm) | Thickness of pipe bend (mm) | Corrosion (mm) | Pressure (MPa) | Temperature (°C) | Fluid density (kg/m3) | Minimum yield stress (MPa) |
|---|---|---|---|---|---|---|---|---|
Gas | 1016 | 18.4 | 22.2 | 1 | 10 | 50 | 95 | 551 |
Oil | 610 | 7.9 | 7.9 | 1 | 9 | 20 | 900 | 551 |
