Assembly of Gas Pressure Test Equipment and Its Application in Oil and Gas Transmission Pipelines

For pipeline construction in sparsely populated and arid regions, pipeline pressure test using gas is a sort of considerably convenient and economical method. Whereas, with the increase of pipeline diameter, old pressure test equipment and corresponding test process have become unsuitable. This paper summarizes the current technical status of mobile air compressors and ultrahigh pressure equipment at home and abroad, puts forward optimized assembly scenario of pressure test equipment system. Taking Tiexi D377 mm oil pipeline as an example, it illustrates the application of the optimized assembly pressure test system. Practice has proved that the optimized assembly pressure test equipment has the advantages of fast pressure increasing speed, short test time period, less fuel and significant economical benefit.
