API – J55 Petroleum Casing
Product Introduction: Petroleum casing is mainly used for drilling oil and gas wells and transporting oil and gas. Due to different geological conditions, the underground stress state is complex, and the comprehensive effects of tensile, compressive, bending, and torsional stresses act on the casing body, which puts high demands on the quality of the casing itself. Once the casing itself is damaged for some reason, it may lead to a reduction in production or even scrapping of the entire well.
