In oilfield operations, the integrity of OCTG (Oil Country Tubular Goods) connections is non-negotiable. Every thread engagement must be precise, smooth, and reliable—especially under extreme torque and pressure. But one persistent issue continues to plague both premium and non-premium connections: galling.

Galling occurs when metal threads rub under pressure, causing adhesive wear, scoring, and surface tearing. It can damage expensive connections and disrupt critical operations.

🔬 How Brush Copper Plating Prevents Galling

Brush Plating deposits a precise, localized layer of pure copper onto steel threads. This soft, ductile layer:

• Acts as a lubricating barrier between mating threads
• Absorbs surface friction, preventing metal-to-metal adhesion
• Provides reliable anti-galling protection, even under high torque
• Supports repeated make-and-break cycles without damaging the threads

Even in harsh environments, copper remains stable, helping maintain thread geometry and sealing performance.

🧪 Field-Tested for the Oil & Gas Industry

Sterling Impreglon Asia’s process is qualified and trusted by major OCTG manufacturers including VAM, JFE, Tenaris, API, and more. We validate every job with:

• Adhesion tape testing
• High-pressure water jet tests (up to 132,000 PSI)
