Modern pipeline steels are low-carbon or ultra-low-carbon microalloyed steels which is a high-tech and high value-added pipeline steel product.
Pipeline steel production has applied almost all the new achievements in process technology in the metallurgical field for many years.
At present, the development trend of pipeline engineering is large pipe diameter, high-cooling and corrosive service environment, and thick-walled submarine pipelines.
API Spec 5L PSL1 X65 (L450) Pipeline Steel Plate is used in Oil and Gas Project.
