When your drilling or workover program demands precision tubular preparation, NAPESCO Australia delivers OCTG machining, make-up, break-out, and thread repair to API-compliant standards — locally in Darwin, reducing logistics risk and keeping your rig on schedule.
Supporting offshore platforms, onshore wells, and intervention operations across the Browse Basin, Timor Sea, and Northern Australia.
From precision thread repair to bucking, hardbanding and phosphating — every service your tubular program needs, delivered locally in Darwin.
Precision CNC thread repair on OCTG tubulars using a Mazak Power Master N with Mazatrol 640 control. Capable of turning pipe from 2⅜" through to 15"+ OD for API and premium connections.
Controlled make-up and break-out of OCTG connections using a fully rotational 70,000 ft-lb hydraulic bucking unit with no-mark jaws for premium connections including VAM, Tenaris, and JFE.
Application and reapplication of wear-resistant alloy weld overlay to drill pipe tool joints, reducing casing wear by up to 50% and extending drill string life up to 3×. Includes end-face grinding for tool joint preparation.
In-house thread phosphating using a purpose-built stainless steel immersion tank with heated solution, providing corrosion protection and improved galling resistance for API and premium OCTG connections.
Comprehensive API thread gauging using a calibrated set of ring and pin gauges across a wide range of pipe sizes. Dedicated climate-controlled gauge room with Mitutoyo precision measurement instruments.
Secondary machining capability using a Hafco Metalmaster shop lathe with DRO for custom parts, sub-adapters, and tooling. Full workshop infrastructure including Trinity 11 screw compressor and 7-tonne forklift for pipe handling.
Invested in the right equipment for OCTG work — not adapted workshop machinery. Every piece of equipment was selected specifically for tubular services.
Hydraulic make-up and break-out unit with dual spindle heads (headstock + tailstock), full 360° rotation, and computerised torque monitoring with automatic PDF report generation.
Heavy-duty CNC lathe with Mazatrol 640 conversational control. Large-bore capacity specifically suited to OCTG pipe diameters, delivering precision thread profiles for API and premium connections.
Dedicated hardbanding machine with induction preheater, motorised pipe roller supports, TWYX fume extractor, and separate drill pipe end-face grinder for tool joint face preparation prior to hardbanding.
Custom-built phosphating bath with stainless steel spray nozzle interior, pneumatic tilting lid, electrical control cabinet, and full chemical storage with spill containment. Purpose-designed for OCTG connection treatment.
When it comes to OCTG services, proximity matters. NAPESCO Australia is the closest OCTG service provider to Darwin — just 25 km away — delivering not just lower transport cost and faster turnaround, but the lowest carbon footprint of any comparable provider in Australia.
The nearest comparable facility is over 1,800 km away. Every kilometre of unnecessary pipe movement adds cost, time, and emissions risk to your program. Choosing NAPESCO Australia means choosing operational continuity, predictable scheduling, and a measurably smaller environmental footprint.
