Protecting underground pipelines from corrosion in sub-zero environments

(NACE International) Northern Canada's permafrost and semi-permafrost environment poses a challenge for designing and building buried oil and gas pipelines. Natural Resource Canada researchers explored and evaluated the use of a certain type of corrosion prevention system, cathodic protection, in permafrost regions. In a paper published in CORROSION journal, the researchers explain how cathodic protection systems function in sub-zero environments and can, when combined with external pipeline coa...
