Pipeline Coating Materials After a Storage Excursion: Hold, Review and Release
Coatings are the first line of defense against corrosion. We explain how to choose them, apply them and keep them working — for every mile of buried and above-grade pipe.
Coating systems
Most popular
01
Polyurea Coatings
Rapid cure, 400%+ elongation and outstanding corrosion resistance — the fastest-growing pipeline protection system.
Internal
02
Pipeline Liners
Polyurea liners that improve flow efficiency and extend the service life of aging lines.
Comparison
03
HDPE vs Polyurea
How three-layer polyethylene stacks up against spray polyurea, metric by metric.
Above-grade
04
Polyaspartic Coatings
Fast-cure, UV-stable aliphatic coatings for splash zones and above-grade rehabilitation.
High temperature
05
Thermal Spray
Metallizing and thermal spray systems for lines that run too hot for organic coatings.
Flow assurance
06
Internal Liners
Reduce friction, fight internal corrosion and keep product moving.
By the numbers
70–80%
of coating failures trace back to inadequate surface preparation.
40–60mils
minimum polyurea build for mainline pipe service.
3–30sec
cure time for spray-applied polyurea — fast return to service.
400%+
elongation, so the coating flexes with soil movement.

| Coating system | Cure time | Thickness (mils) | Best for | Temperature range | UV resistance |
|---|---|---|---|---|---|
| Spray Polyurea Most versatile | 3–30 seconds | 40–250 | Field joints, rehab, high-impact areas | -40°F to 250°F | Moderate |
| Fusion Bonded Epoxy (FBE) | Minutes (factory) | 14–20 | Mainline new construction | -40°F to 140°F | Low |
| Three-Layer Polyethylene (3LPE) | Factory applied | 60–120 | HDD, rocky trench, abrasive soils | -40°F to 140°F | Excellent |
| Polyaspartic | 30 min – 2 hrs | 20–80 | Above-grade, splash zone rehab | -30°F to 200°F | Excellent |
| Coal Tar Epoxy | 24–48 hours | 10–20 | Legacy systems, submerged service | -20°F to 120°F | Poor |
| Liquid Epoxy | 4–24 hours | 10–30 | Field repair, irregular shapes | -20°F to 150°F | Low |
