Common Technique for Hydrostatic Tests of Large-diameter and Long-distance Oil and Gas Pipelines

Sectioning principles and main operation points of hydrostatic tests on large-diameter and long-distance oil and gas pipeline are presented and control methods for the test process are covered as well. It is considered that to observe and record the experimental parameters of water injection, hydrostatic test and water discharge are highly necessary, which is a key point to carry on the hydrostatic test and realize quantitative control on the hydrostatic test process.
