After a period of time, it is checked whether the gas pressure in the gas pipeline has dropped. If the pressure drops, it can be considered that there is a leak in the gas pipeline. For some small welding trachoma, the inspection workers need to carry a ladder, climb up and down to inspect the welding parts in turn, which consumes a lot of physical strength; the monitoring work is slow; at the same time, the monitoring is not comprehensive, and the gas pipeline transportation process or other external reasons, It can also cause cracks in the gas pipeline. The inspection workers often ignore this aspect, so that the leaking parts are found and repeated operations are carried out many times, which affects the construction progress.
