Galling Under Pressure: How We Test Our Brush Plating at 3,000 PSI

In the oil and gas industry, thread protection is essential. Whether for premium or non-premium OCTG connections, every tool must perform under extreme torque, pressure, and repeated make-and-break cycles. One of the most common and costly issues faced in the field is thread galling—and the solution lies in our proven Brush Copper Plating technology.

At Sterling Impreglon Asia, we do not just promise performance—we back it with real testing. Our Brush Plating process is validated through stringent quality control checks, including the high-pressure water jet test at 3,000 PSI (230 bars).

🔍 Why Galling Happens in OCTG Threads

Galling occurs when unprotected metal threads seize, tear, or lock up during engagement—especially under high torque. This happens due to:

• Metal-to-metal contact with no lubricating layer
• High stress from make-and-break operations
• Repeated use without adequate surface protection

This can lead to damaged threads, failed sealing, or rejected tools—a costly and avoidable issue.

🛡 How Brush Plating Prevents Galling

Our Brush Copper Plating process applies a soft, uniform copper layer to OCTG threads. This copper layer:

✔️ Reduces friction and prevents seizure during makeup/breakout
✔️ Acts as a sacrificial anti-galling barrier
✔️ Allows for multiple reuses of premium and non-premium connections
✔️ Is approved by leading manufacturers such as VAM, JFE, Tenaris, Hunting, and NOV

💪 Tested at 3,000 PSI for Reliable Performance

Every Brush Plating job we complete goes through rigorous testing, including:

🔸 High-Pressure Water Jet Test (3,000 PSI / 230 Bars)
— Simulates real-world drilling and production pressures
— Confirms that the copper plating remains intact without flaking or peeling

🔸 Adhesion Tape Test
— Ensures the copper layer is properly bonded to the base metal

🔸 Thickness and Visual Inspection
— Verifies plating consistency across all thread surfaces

These tests ensure that every component we plate can handle extreme field conditions with confidence.

🧠 Why This Matters for Your Operations

In critical oilfield operations, equipment failure due to galling can result in:

❌ Expensive tool replacement
❌ Unplanned rig downtime
❌ Qualification test failures
❌ Damaged reputation with operators

That’s why it’s vital to protect your connections with proven solutions like Brush Plating—tested up to 3,000 PSI and trusted by top-tier operators around the world.
