At Kriloha Ltd., we supply Drill Stem Subs, essential drill string components that provide connectivity, protection, and versatility in drilling operations. Types include bit subs, saver subs, lift subs, and cross-over subs, each serving a critical role in drilling efficiency and string integrity. Manufactured from forged alloy steels, Kriloha drill stem subs are designed for high torque transmission and fatigue resistance under HPHT drilling conditions. Applications include cross-over between different connection types, protecting expensive drill pipe threads, providing lifting points, and connecting drill bits. Each sub undergoes ultrasonic testing, thread gauging, torque testing, and dimensional verification, ensuring long service life.
