Problem of estimation of frozen dispersed ground corrosion activity in cryolithozone
Corrosion of metals in ground causes huge material damage to pipeline transport and ecology. There are tens of thousand kilometers of gas and oil pipelines in cryolithozone. However, ground corrosion activity in cryolithozone has not been well-founded yet. There are no reliable criteria for estimating ground corrosion activity in cryolithozone. In the article we adduce data about the high rate of depth corrosion of pipelines in the ground of cryolithozone, wood and steppe zones. We have come to a conclusion that high ground corrosion aggression in cryolithozone occurs due to the transportation of warm gas and the high content of hydrogen protons in ground porous solutions.
