Technical Field
The utility model relates to an on-line monitoring field of gas pipeline especially relates to an on-line monitoring system of remaining life of gas pipeline's sacrificial anode.
Background
High-pressure gas pipelines buried in cities are generally made of metal materials such as stainless steel. Because the underground environment is complex, factors such as moist acid and alkali can all corrode and infringe the gas pipeline, once the pipeline is perforated and damaged, immeasurable damage can be caused to the life and property safety of people. The corrosion protection of the gas pipeline is generally protected by externally connecting a more active metal object (i.e., a sacrificial anode), so that the corrosion of the environment to the gas pipeline is shown as the corrosion to the sacrificial anode. The sacrificial anode is effective to protect the gas conduit from corrosion, but once the sacrificial anode has been corroded away, the gas conduit is thus unprotected. Because the corrosion rate of the sacrificial anode is closely related to the environment and is generally buried underground, whether the sacrificial anode is completely corroded is not easy to observe in time, particularly, after a long time, the sacrificial anode of the gas pipeline is completely corroded, a manager of the condition that the gas pipeline is not protected can not know that the leakage risk of the gas pipeline is easy to occur.
