With the continuously growing demand in energy consumption, the exploration of oil and gas from the remote northern area has become an integral part of the energy industry. Development of high-strength steel pipeline technology provides a reliable and economic means for energy transportation. However, the pipeline operation unavoidably encounters severe environmental and technical challenges to maintain its integrity in the North. Corrosion and stress corrosion cracking (SCC) are two major factors to result in pipeline failure.

随着能源消费需求的不断增长，北方偏远地区油气勘探已成为能源工业不可或缺的一部分。高强度钢管道技术的发展为能源输送提供了可靠、经济的手段。然而，管道的运作不可避免地遇到了严峻的环境和技术挑战，以保持其在北部的完整性。腐蚀和应力腐蚀开裂（SCC）是导致管道失效的两个主要因素.
