Oil & Gas Drilling Wire Rope
TJ Steel Rope manufactures wire rope to API RP 9A, the American Petroleum Institute standard for oil and gas drilling and production applications, including drilling line and rotary line service. These constructions are built for the loading and fatigue conditions specific to drilling rig operation, and diameters extend beyond the standard 80mm catalog maximum for oil-drilling and mining-grade specifications on request. Contact the sales team for API RP 9A construction and diameter availability.
Selecting rope for drilling operations
Endurance for the drill floor
Drilling line and rotary line work under cyclic load with constant spooling — conditions that retire rope through fatigue rather than a single overload. Our API RP 9A constructions are built for it, in diameters beyond the standard 80 mm catalog maximum on request.
