| Abstract: | With an aim to retard the the corrosionthat mineral gas pipes buried in chemical and electrochemical corrosion. The progress of the corrosion of gas pipes and prolong their using time, the earth usually suffered is analyzed. They are mainly subject to damage of anticorrosive layer of pipe outer wall quickens the corrosion of the outer wall, and eventually causes a puncture. Several protective measures are proposed for relevant firms to take into consideration. |
