Study on Air Resistance of Natural Gas Long-distance Pipelines Hydraulic Test in Mountain Area
Pressure testing is an important step in the construction process of long-distance pipelines.Mountain area is prone to have large drops due to terrain problems.The phenomenon of air resistance is prone to occur in the process of drainage in the hydraulic test,so the hydraulic test has become a major problem in the construction of pressure testing.Combined with the Yuanba-Deyang gas distribution project of the long-distance pipelines construction project in mountain area,the causes of gas resistance are analyzed,and the corresponding preventive measures and solutions are put forward to provide reference for the construction of pipelines in mountain area with large drops.
