High-torque-resistant drill pipe featuring double‑shoulder drill pipe joints (DSTJ) offers superior torque‑carrying capacity compared to standard API connections, making it an ideal choice for ultra‑long horizontal wells, horizontal wells, and deep‑well drilling operations.
Sulfide‑resistant drill pipe compliant with NACE MR0175 / ISO 15156, available in SS95, SS105, and SS135 grades. Specifically engineered for sour oil and gas fields, it effectively resists sulfide stress cracking in H₂S environments.
