Product Description

Frigate’s downhole fittings are API-compliant, heavy-wall connection components designed to maintain structural and sealing integrity within highly abrasive and high-temperature wellbore profiles. Built for seamless integration into technical completions, these fittings minimize non-productive time (NPT) by mitigating mechanical fatigue and chemical degradation in critical subsurface flows.

Size Range (OD)

0.5 inch up to 7.0 inches (12.7 mm to 177.8 mm) standard; custom diameters available

Wall Thickness Tolerances

CNC-precision matched within ± 0.025 mm to prevent turbulent flow erosion

Surface Finish / Coating

Electroless Nickel Plating (ENP), Zinc-Phosphate, or QPQ Liquid Nitriding for low friction

Yield Strength Range

80,000 psi to 125,000 psi minimum yield strength based on metallurgical selection

Corrosion Resistance

Highly optimized for sour gas (H2S), high chloride (Cl-), and high carbon dioxide (CO2) fluids

Nondestructive Testing (NDT)

100% Hydrostatic testing, Dye Penetrant (DP), Magnetic Particle (MPI), and Ultrasonic testing

Traceability

Full MTRs (Material Test Reports) per EN 10204 3.1; laser-etched heat numbers on each component

Design Validation

Finite Element Analysis (FEA) simulated for combined axial tension and high burst/collapse pressures

Sealing Mechanism

Primary metal-to-metal elastomeric-free sealing with secondary elastomeric backup tracks

Application Environment

Onshore, Offshore Deepwater, High-Pressure High-Temperature (HPHT), and Sour Service wells

Technical Advantages

By utilizing high-precision CNC multi-axis turning and advanced FEA design validation, Frigate eliminates the micro-surface defects that trigger stress corrosion cracking in high-vibration wellbore segments. Our rigorous quality management framework guarantees exact concentricity and tight-tolerance premium threads, minimizing the total cost of ownership by preventing premature subsurface assembly failures.

Industry Applications

High-Pressure High-Temperature (HPHT) Completions

Engineered to withstand extreme thermal expansion and mechanical loading in ultra-deep wells, preventing catastrophic pressure loss where standard elastomer-reliant seals fail.

Deepwater Subsea Production

Designed with corrosion-resistant alloys to guarantee multi-decade structural integrity in inaccessible subsea trees and manifolds, reducing high-cost intervention risks.

Sour Service & Acid Gas Injection

Metallurgically certified under NACE MR0175 to completely resist hydrogen embrittlement and sulfide stress cracking in environments with high concentrations of H2S and CO2.

Hydraulic Fracturing & Flowback Operations

Built with case-hardened interior bores to withstand high-velocity, abrasive proppant slurries and corrosive chemicals during stimulation and early production phases.

Intelligent Well Completions

Precision machined to safely house downhole control lines, fiber optics, and electronic sensors while maintaining complete structural sealing integrity across zones.

Artificial Lift Systems

Optimized for compatibility with ESP (Electric Submersible Pump) and gas lift strings, ensuring stable fluid flow dynamics and resisting wear from systemic vibrations.

Frigate Approved Quality Management System

At Frigate, quality is built into every stage of manufacturing. Our approved Quality Management System ensures that every material component.

Having Doubts? Our FAQ

Does Frigate supply full Material Test Reports (MTRs) with downhole fittings?

Yes. All downhole fittings manufactured by Frigate come standard with complete EN 10204 3.1 Material Test Reports, certifying heat numbers, chemical composition, mechanical properties, and NDT compliance for full traceability.

Can you machine custom proprietary thread profiles or only standard API threads?

We routinely machine standard API (EUE, NUE, LP) connections as well as premium gas-tight, metal-to-metal sealing profiles. Our engineering team can work directly from your detailed CAD models or proprietary specifications to match exact completion requirements.

How does Frigate ensure the quality of exotic alloys like Inconel 718 or Super Duplex?

We source raw materials exclusively from approved, tier-one mills. Furthermore, our internal quality control mandates comprehensive Positive Material Identification (PMI) testing alongside ultrasonic evaluation prior to CNC machining to rule out any subsurface metallurgical flaws.

What options do you offer for high-wear or highly abrasive slurry applications?

For high-erosion environments, we offer specialized internal surface treatments including Electroless Nickel Plating (ENP), QPQ liquid nitriding, and hard-facing overlays. These significantly increase surface hardness and lower friction coefficients to mitigate erosion from proppants or sand.

How do you handle expedite requests for sudden non-productive time (NPT) drilling crises?

Frigate maintains strategic reserves of standard API-grade steel billets. For emergency well-intervention scenarios, we can activate an expedited manufacturing track to bypass standard lead times and ship emergency turnaround components in as little as 48 to 72 hours.
