Before commissioning, each gas network must be checked to ensure its leak-tightness. This tutorial guides you through the steps of these two essential tests. Start with the mechanical test, performed after backfilling the structure, using dry air at a pressure of 6 bars for 2 hours. Learn how to connect the pipe, gradually increase the pressure, and foam the fittings to detect possible leaks. The results must be recorded in a test report for validation. Next, proceed to the leak test, generally performed by the network operator. The method depends on the length of the network: for networks longer than 200 meters, the test is performed in air and lasts 48 hours at a pressure of 0.9 bar. Learn how to measure absolute pressures and verify the pressure difference to ensure leaktightness.
