Major Systems
We offer a complete range of tubular products, including tubing, casing, couplings, specialty pipes, and anti-corrosion goods. Our extensive portfolio is designed to meet your tubular requirements across the entire operational workflow, from drilling and well completion to oil production and workover.
Our tubular goods are engineered to perform in extreme operating environments, including deep and ultra-deep wells, high temperature and high pressure (HPHT), and highly corrosive settings. They are highly versatile, supporting the development of diverse reservoirs ranging from conventional oil and gas to heavy oil, shale gas, and coalbed methane.
We tailor material and wall thickness schemes to match your specific well conditions, including depth, temperature, pressure, and corrosion levels. Backed by full-lifecycle tubular management and intelligent inspection systems, we ensure complete traceability of incoming materials, operational control during service, and proactive risk prevention.
