Industry Applications

Upstream Oil & Gas Exploration

Engineered for wellheads, Christmas trees, and manifolds, these valve bodies reliably control high-pressure crude and sour gas under extreme structural loads.

Midstream Pipeline Infrastructure

Designed to facilitate high-flow custody transfer, transport networks, and compressor stations, ensuring zero-leakage isolating performance over vast distances.

Supercritical Thermal Power Plants

Built to withstand ultra-high temperature steam loops, preventing thermal fatigue and maintaining mechanical integrity in heavy-duty turbine generation.

Liquefied Natural Gas (LNG) Supply Chain

Utilizes specialized cryogenic-grade alloys optimized to prevent embrittlement during freezing containment, transport, and regasification processing.

Green Hydrogen Production & Storage

Machined with advanced surface treatments to eliminate hydrogen permeation, protecting critical storage arrays and high-pressure blending loops.

Offshore Subsea Operations

Heavy-wall forged valve bodies designed with anti-corrosive claddings to resist deep-sea hydrostatic pressure and marine atmospheric exposure.

Having Doubts? Our FAQ

What measures does Frigate take to prevent hydrogen embrittlement in energy sector valve bodies?

We strictly utilize raw materials compliant with NACE MR0175/ISO 15156 standards for sour service environments. Additionally, we employ controlled heat-treatment protocols and offer specialized corrosion-resistant alloy (CRA) cladding, such as Inconel 625 weld overlay, to isolate the substrate from volatile media.

Can you provide complete material traceability for critical high-pressure components?

Yes. Every valve body shipped by Frigate comes with a comprehensive quality documentation package. This includes Mill Test Certificates (MTC) to EN 10204 Type 3.1 or 3.2, chemical analysis, mechanical testing reports, and complete heat-number traceability.

How does Frigate optimize Total Cost of Ownership (TCO) for custom valve body castings?

By combining our Design for Manufacturing (DFM) reviews with precision near-net-shape casting practices, we significantly reduce raw material wastage and secondary CNC machining hours. This lowers initial procurement costs while extending the service life of the valve via superior metallurgy.

What non-destructive testing (NDT) protocols are performed on subsea valve bodies?

Subsea components undergo 100% rigorous NDT testing. This typically includes volumetric inspections via Radiographic Testing (RT) or Ultrasonic Testing (UT) to detect internal anomalies, alongside surface testing using Magnetic Particle (MT) or Liquid Penetrant (PT) inspections.

Do you accommodate custom or modified valve body designs for unique envelope dimensions?

Absolutely. Our engineering team collaborates directly with your procurement and technical teams to adapt face-to-face dimensions, wall thicknesses, and flange configurations to fit your legacy footprints or proprietary internal trim designs perfectly.
