Table 8 Checking of the maximum displacement of oil pipeline
From: Stress analysis of parallel oil and gas steel pipelines in inclined tunnels
Loading conditions | Maximum axial displacement | Maximum vertical linear displacement | Maximum angular displacement | |||
|---|---|---|---|---|---|---|
Absolute value (mm) | Location | Absolute value (mm) | Location | Absolute value (°) | Location | |
Operating case of oil pipeline | 0.44 | Bend 1 | 1.85 | Bend 1 | 0.03 | Bend 1 |
Sustained case of oil pipeline | 0 | – | 0.06 | Fixed pier 1 | 0.001 | Fixed pier 1 |
Expansion case of oil pipeline | 0.44 | Bend 1 | 1.85 | Bend 1 | 0.03 | Bend 1 |
Pigging case of oil pipeline | 0.44 | Bend 1 | 1.87 | Bend 1 | 0.04 | Bend 1 |
Pressure test case of oil pipeline | 0.29 | Bend 1 | 1.22 | Bend 1 | 0.02 | Bend 1 |
