The differences in Chinese and Russian pipeline pressure testing standards

Main pipeline pressure testing standards between China and Russia are introduced, and the differences them are analyzed in detail, including the pipe section length, testing medium, strength testing pressure, tightness testing pressure and pressure holding time, process piping pressure testing of gas or oil stations, leakage inspection methods of process piping pressure testing, piping pressure technology under 0 ℃, mandatory pressure testing (re-testing and periodic tesing), piping pressure monitoring, safety measures of pressure testing and environment protection. Finally, Recommendations to draw up and revise the standards about the pipeline constructed in the permafrost are given.
