Why FBE coating is the preferred choice for pipeline protection
FBE chemically bonds to the steel substrate, forming an inseparable protective layer with adhesion strength exceeding 2000 psi.
Dual-layer FBE withstands operating temperatures up to +110°C, suitable for hot oil and district heating pipelines.
Rapid induction heating and electrostatic spray application. FBE cures in seconds, enabling high-throughput production.
Excellent cathodic disbondment resistance ensures compatibility with cathodic protection systems for long-term pipeline integrity.
Zero VOC emissions during application, no solvents, and fully recyclable overspray powder make FBE an environmentally responsible choice.
FBE maintains integrity during pipe bending (≥2.5° per diameter length), making it suitable for field bends and cold-forming operations.
Where FBE coated pipes deliver maximum value
Cross-country transmission pipelines requiring reliable buried corrosion protection with cathodic protection compatibility.
Dual-layer abrasion-resistant FBE for horizontal directional drilling installations through rocky or abrasive soil conditions.
AWWA C213-compliant FBE for large-diameter potable water transmission pipelines with internal and external coating.
Internal FBE lining for chemical resistance in process piping, protecting against corrosive media and reducing flow friction.
FBE coated steel pipe for city gas distribution mains, service lines, and metering stations with excellent soil stress resistance.
FBE external coating for API 5CT casing strings in corrosive oilfield environments with H2S and CO2 exposure.
FBE coated reinforcing steel (rebar) for concrete structures in marine environments, bridges, and parking structures requiring corrosion protection.
High-temperature dual-layer FBE for district heating supply and return lines operating at elevated temperatures.
