Buried Pipeline Protection

Long-term corrosion protection for underground pipelines — from soil stress to cathodic disbondment.

Pipeline Corrosion Challenges Underground

Soil Corrosion — Moisture, salts, and chemicals in soil accelerate metal corrosion, making detection and repair difficult once buried.

Mechanical Damage — Backfill rocks and soil stress can puncture or damage coatings during and after installation.

Cathodic Disbondment — Poor coating compatibility with CP systems leads to coating peeling and accelerated corrosion at holidays.

Our Solution: Multi-Layer Buried Pipeline Protection

We provide a complete anti-corrosion system for buried steel pipelines — combining high-performance coatings, cathodic protection compatibility, and mechanical strength. Our solution is suitable for long-distance oil & gas pipelines, water transmission mains, and industrial buried piping.

Solution Components

Anti-Corrosion Primer — Solvent-free epoxy primer for strong adhesion to steel and compatibility with CP systems.
Cold-Applied Tape — Polyethylene or polypropylene tape for mainline corrosion protection; cold application, no heating required.
Heat Shrink Sleeve — For field joint coating; seamless, high-strength protection compatible with 2PE/3PE/FBE systems.
Outer Wrap (Optional) — Additional mechanical protection for rocky terrain or high-stress burial conditions.

Why Our Buried Pipeline Protection Stands Out

CP Compatible — Excellent cathodic disbondment resistance (tested to ISO 21809-3).
High Mechanical Strength — Fiber-reinforced options available for rocky terrain.
Wide Temperature Range — Suitable from -45°C to +95°C.
Proven Performance — Used in major projects including West-East Gas Pipeline.
Complete System — Primer + mainline tape + field joint sleeve, one-stop supply.
