🔬 Why OEMs Approve Sterling’s Brush Plating
Major OCTG manufacturers demand precision and reliability because thread integrity directly impacts drilling, extraction safety and performance.
Sterling’s Brush Plating is approved because it delivers repeatable, traceable, and consistent results, including:
✔ True Metallurgical Bonding
Our plating forms an
atomic-level bond, ensuring the copper deposit will not peel or delaminate — even under repeated make-up and high torque.
✔ Superior Adhesion Strength
Our coatings consistently pass
high-pressure water jet tests of up to
200 bar, demonstrating exceptional durability.
✔ Uniform Coating Thickness
Every plated thread is restored with controlled, even thickness — ensuring smooth make-up and consistent connection performance.
✔ Proven Anti-Galling Protection
The copper layer provides a soft, lubricating barrier that eliminates metal-to-metal welding, reducing galling incidents to near zero.
✔ Globally Recognized Training & Qualification Standards
Sterling technicians follow OEM-approved methods, ensuring the plating process remains fully compliant with international threading specifications.
⚙️ Not Just Qualified — Field-Proven in Real Drilling Conditions
Approval alone is not enough.
What truly matters is how the plating performs in actual oilfield environments.
Sterling’s Brush Plating has been field-tested in:
- High-temperature drilling applications
- Deep HPHT wells
- Offshore operations
- Premium and non-premium connections
- Repeated make-up and break-out cycles
The result:
Outstanding reliability, minimal galling, and extended tool life.
The world’s leading manufacturers trust Sterling because they have seen the long-term results — not just laboratory data.
