Greno Industries provides oil and gas machining services to the global petroleum industry. We support tier-1 OEMs, energy producers, and oilfield service companies with large parts that withstand extreme pressures (HPHT), corrosive environments, and severe mechanical stress.
From custom drilling prototypes to high-volume production of rugged subsea and surface components, our Made in USA manufacturing combines heavy-duty capabilities with tight-tolerance precision to keep your operations running safely and efficiently.
Greno know from experience that the petroleum industry demands absolute structural integrity. At our Made in USA facility, we use multi-axis CNC machining, large-diameter turning, and deep-hole processing to produce parts that meet tough specifications.
Offshore platforms and high-load exploration fields rely on massive components that cannot compromise on dimensional accuracy.
Capacity: Turning capabilities up to 5 feet (60 inches) in diameter and parts weighing up to 4,000 lbs.
Applications: Massive pistons, large adaptor rings, and robust cement heads.
When downhole tools require perfectly straight, ultra-deep bores with superior surface finishes, our specialized gun drilling services provide the answer.
We hold tolerances as tight as 0.005 inches over extended lengths, ensuring optimal fluid flow and structural reliability in high-pressure environments.
Our 3-axis and 4-axis CNC milling centers manipulate complex geometries efficiently, reducing setups to maximize part consistency and speed up lead times for intricate flow-control and rigging components.
We machine complex, high-performance parts for upstream exploration, midstream transport, and downstream processing equipment.
| Component Category | Machined Metal Parts |
|---|---|
| Flow Control & Valves | Gate valves, valve seats, cylinder plates, metal seals, and GIS valves. |
| Pumps & Compressors | Compressor discs, pump impellers, turbo-expanders, and turbine plates. |
| Downhole & Rigging | Ram shafts, locking bars, cement heads, and heavy-duty adaptor rings. |
| Fasteners & Hardware | High-tensile custom fasteners, specialty studs, and high-stress connectors. |
Standard metals fail quickly under sour gas exposure, high temperatures, and corrosive marine conditions. Greno specializes in the precision machining of superalloys and high-temperature metals that traditional machine shops struggle to cut.
We routinely work with:
Inconel (625, 718): Highly resilient against oxidation and corrosion; ideal for blowout preventers (BOPs), ram shafts, and high-stress downhole tools.
Stainless Steels (Duplex & Super Duplex): Providing exceptional pitting resistance in saltwater environments.
Titanium & Carbon Steel Alloys: Optimized for weight-to-strength ratios and heavy industrial structural loads.
At Greno, quality isn’t checked at the end—it is integrated into every phase of our workflow. Our quality management system guarantees compliance and traceability from raw material to final delivery.
Certifications & Compliance: AS9100 Certified, ITAR Registered, CAGE Code 62654, and NAICS 339999.
Non-Destructive Testing (NDT): In-house precision measurement and rigorous inspection to ensure zero-defect production for hazardous operating environments.
Lifecycle Engineering Support: We offer CAD/CAM programming, collaborative engineering, and precision reverse-engineering to replicate or upgrade obsolete OEM parts and legacy components.
Full-Service Assembly & Finishing: From precision industrial welding (MIG/TIG/Stick) and surface treatments to final kitting, packaging, and international export logistics.
When failure is not an option, the energy sector counts on Greno Industries. Our combination of advanced heavy equipment, experience with exotic superalloys, and disciplined quality control makes us the preferred manufacturing partner for critical oilfield applications.
