Precision Welding for Mission-Critical Oil & Gas Instrumentation

Engineering Leak-Free Integrity for High-Pressure Gas Systems, Refineries, and Offshore Platforms.

Industry Overview

In the demanding environment of oil refineries and offshore rigs, instrumentation tubing is the nervous system of the facility. Handling volatile gases and corrosive chemicals under extreme pressure requires welding joints of the highest caliber. Manual welding in these complex, multi-layered pipe skids is not only slow but prone to inconsistencies.

FYID-Feiyide’s automated orbital TIG welding technology is the trusted choice for global energy projects. We provide the stability and repeatability needed to ensure that every instrumentation joint survives the harshest vibrations and thermal cycles.

Critical Challenges We Address

  • Zero-Leak High Pressure Integrity: Our pulse TIG control ensures deep, consistent penetration, vital for tubing that must withstand pressures exceeding 10,000 PSI without a single leak.

  • Exotic Material Expertise: We specialize in welding corrosion-resistant alloys commonly used in petrochemicals, including Duplex, Super Duplex, Inconel, and Monel.

Perfect orbital weld on corrosion-resistant Duplex steel tubing, validated for 100% X-ray quality in oil and gas applications.

  • Complex Space Constraints: Manifolds and instrument skids are often cramped. The FYID FXT20 power source and our ultra-compact C-series heads are designed to fit where manual torches and bulky competitors cannot.

  • 100% X-Ray Quality: Achieve a nearly 100% pass rate for non-destructive testing (NDT). Our digital logic ensures stable arc strikes and controlled crater fills, eliminating porosity and cracks.

Featured Equipment

  • FXT20 Digital Power Source: Portable, rugged, and intelligent—perfect for on-site construction and offshore maintenance.

  • C-Series (Small Diameter) Heads: Optimized for 1/8" to 1" instrumentation tubing with total gas shielding.

  • Tungsten Grinding Tools: Ensuring the precise electrode geometry required for consistent arc starting in critical energy applications.

Technical FAQ 

  • Q: Can FYID orbital welders handle the thick-walled instrumentation tubes used in high-pressure gas systems?

    • A: Yes. Our FXT20 power source offers sophisticated pulse control that manages heat input effectively, allowing for full-penetration welds on heavy-wall instrumentation tubing without overheating the material or causing distortion.

  • Q: Is the FYID equipment portable enough for offshore rig maintenance?

    • A: Absolutely. The FXT20 is 33% more compact than traditional orbital power sources. Its lightweight, integrated design makes it easy to transport via helicopter or crane to offshore platforms for critical repair and installation work.
