Computer-controlled lathe and machining-center work that produces precision oilfield components from bar stock, forgings, or castings. Covers turning, milling, drilling, and boring to tight tolerances for parts such as subs, mandrels, housings, and pressure-control internals.

Cutting of API and proprietary premium threaded connections on drill pipe, casing, tubing, and line pipe. Includes pin and box machining, rotary shouldered connections, and recutting or repairing damaged threads to gauge.

Build-to-print and made-to-order production of customer-specified parts, typically in low-to-medium volume. Used by operators and OEMs to outsource component manufacture against supplied drawings and material specifications.

Machining and welding of corrosion-resistant alloys, duplex stainless, and high-nickel grades (e.g., Inconel, Monel) for sour-service and severe-environment applications. Requires controlled tooling, feeds, and procedures to manage work-hardening and metallurgy.

Manufacture of studs, bolts, nuts, and threaded fasteners in alloy steels and CRAs for flanges, wellheads, and pressure equipment. Includes thread cutting or rolling, coating, and dimensional verification.

Restoration of worn or damaged oilfield parts through re-machining, build-up, and re-threading, including bearing replacement and journal regrinding on rotating equipment. Returns serviceable components to original or upgraded specification.

Controlled assembly and disassembly of threaded connections using a bucking unit that applies and records calibrated torque. Used to make up tool joints, subs, and downhole assemblies to specified make-up torque.

Machining performed under an API-monogrammed and ISO 9001 quality system with documented procedures, traceability, and inspection. Required for components carrying API marking or supplied into API-licensed product lines.
