Recently, the industry standard for "Hot-rolled Wide Steel Strips for Oil and Gas Well Casing and Tubing," led by Hebei Iron and Steel Group Handan Iron and Steel Company, has officially come into effect. This industry standard fills a gap in the field of hot-rolled wide steel strips and has been comprehensively evaluated to reach an internationally advanced level.

Casing and tubing for oil and gas wells are classified by production processes into electric resistance welded (ERW) pipes and seamless pipes. Compared to seamless pipes, ERW pipes offer advantages such as higher dimensional accuracy in wall thickness, better weld toughness, superior resistance to extrusion, easier quality control, and lower costs.

In recent years, with the development of steel smelting and rolling technology in our country, as well as the improvement in welding technology, the use ratio of welded casings has gradually increased. Correspondingly, the demand for hot-rolled wide steel strips for oil and gas well casings and tubing from pipe manufacturing enterprises has also been gradually increasing. Handan Iron and Steel has transformed its production line equipment and technological advantages into product advantages, achieving steady improvements in both the quality and market share of hot-rolled wide steel strips for oil and gas well casings and tubing.

Handan Iron and Steel Company has been closely aligned with the development needs of the steel industry, focusing on key common challenges within the industry, continuously innovating in process and product application technology research, and actively leading or participating in the formulation of national and industry standards. This time, Handan Iron and Steel Company led the development of the industry standard for "Hot-Rolled Wide Steel Strip for Oil and Gas Well Casing and Tubing," which applies to hot-rolled wide steel strips for oil and gas well casing and tubing with a thickness not exceeding a specified value. The standard specifies the grades, order contents, dimensions, shape, weight, technical requirements, test methods, inspection rules, packaging, marking, and quality certificate for hot-rolled wide steel strips used in oil and gas well casing and tubing.

The formulation and implementation of this standard will significantly reduce the technical agreement content in the ordering process between downstream users and steel mills for oil and gas well casings and tubing, thereby promoting the healthy development of the industry for hot-rolled wide steel strips used in oil and gas well casings and tubing in China.
