[PDF] Low temperature tensile properties of line pipe analysis of the corrosion scales formed on api 5l x70 and

Given the expected increase in Arctic oil and gas exploitation, there is a demand for high-strength line pipe steels able to cope with the Arctic climate. The state-of-the-art of the tensile properties of API 5L steels at low temperatures is reviewed and discussed. Well-known characteristics such as an increase in strength and Youngs modulus with decreasing temperatures are confirmed.X70 Steel | Scientific.NetThe average corrosion rate was the highest when NO 2 or SO 2 was included, followed by H 2 S, and the average corrosion rate was the smallest when O 2 was contained. Among them, X70 steel suffered local corrosion when NO 2 was contained.
