Dry air drying technology made its debut in West-East Gas Transmission
For the first time, dry air drying technology was applied to the 22-gauge section of the West-East Gas Pipeline, filling a gap in China's large-diameter pipeline construction. Pipeline dry air drying technology is a new type of technology emerging in the world in recent years. In the past, domestic and foreign natural gas pipeline constructions used water or gas as pressure tests. After the pressure test was completed, the water vapor was discharged through a pipeline sweeper. This method can not guarantee the complete discharge of moisture in the pipeline. Natural gas contains a large amount of acidic compounds. After entering the pipeline, it meets with the remaining moist air and forms a viscous crystalline hydrate on the wall of the pipeline. Crystal hydrates accumulate and eventually cause plugging of the pipe. Pipeline drying technology is an important way to solve this problem. It was Pipeline IV's Special Projects Department that served this drying task. This team has a wealth of experience in the construction of pipeline special operations, mastered a wide range of professional skills, in the construction of China's pipelines repeatedly build war effort. In recent years, Pipeline IV has made great efforts to nurture special engineering teams and invested heavily in the introduction of 5 (Taiwan) sets of large-displacement air compressors and vacuum drying equipments with international leading level, which has become China’s exclusive ownership and mastery of professional equipment. , professional technology, professional team of pipeline special engineering enterprises.
