Recently, Shandong Steel's high-end pipeline steel successfully entered a leading domestic enterprise specializing in marine engineering and energy steel pipes and achieved batch supply. This marks another authoritative recognition for Shandong Steel Group in the field of high-end heavy plates (Introduction) for marine engineering and energy, opening up a new channel for expanding the market for steel used in energy projects.

This benchmark company has long focused on marine engineering equipment, long-distance energy pipelines and other fields. Its products are used in harsh scenarios such as high-pressure oil and gas transportation and marine engineering, which have extremely high requirements for pipeline steel performance. The X70M pipeline steel used in this collaboration was delivered using TMCP (Thermomechanical Control Process), which places extremely high demands on the entire manufacturing process control.
Shandong Steel strictly controls the purity and inclusion level of molten steel in the smelting process to ensure quality from the source; it sets process parameters in the rolling process to ensure stable plate shape and dimensional accuracy; and it precisely controls the water inlet and final cooling temperatures in the cooling process to ensure optimal microstructure and properties. At the same time, a standardized management and quality traceability system was built for the entire process, realizing closed-loop data management and traceability of steel plates, which has been highly recognized by users.
