Coated Steel Pipe – FBE, 3PE, CWC, Epoxy
Anti-Corrosion & Insulation Coatings for Oil & Gas, Water, Offshore, and Industrial Pipelines
What Is Coated Steel Pipe?
Coated steel pipe refers to carbon steel pipe with an external or internal protective layer applied to prevent corrosion, reduce friction, or provide thermal insulation.
Bare carbon steel, when buried or submerged, corrodes at rates of 0.1–1.0 mm per year depending on soil/water chemistry. A properly selected and applied coating system extends pipeline service life to 30–50 years.
Coating is not an accessory. It is an engineered system.
Coating Selection Guide – Six Questions You Must Ask
1. What is the operating temperature?
-
≤ 60°C: 3PE standard grade, FBE standard grade
-
60–80°C: 3PE high-temp grade, FBE dual-layer
-
80–110°C: FBE high-temp (special formulation), 3PP
-
110°C: 3PP, epoxy novolac (liquid)
2. Is the pipeline buried, submerged, or above-ground?
-
Buried: 3PE or FBE + mechanical protection
-
Submarine: CWC + 3PE/FBE corrosion layer
-
Above-ground: FBE or 3PE with UV-resistant topcoat
-
Internal lining: Liquid epoxy for water/chemicals
3. Can the coating be applied in the field?
-
Shop only: FBE, 3PE, 3PP, CWC, PU foam
-
Field applicable: Liquid epoxy (repairs, girth welds, touch-up)
4. What is the fluid being transported?
-
Potable water: Liquid epoxy (NSF/ANSI 61 certified grades) or cement mortar
-
Produced water: FBE or liquid epoxy
-
Oil/gas: 3PE or FBE
-
High-temp gas: 3PP or FBE high-temp
5. Is mechanical damage expected?
-
Rock backfill, HDD: Dual-layer FBE or 3PE with reinforced topcoat
-
Trenchless installation: Abrasion-resistant overcoat
6. What is the design life?
-
≤ 20 years: FBE single-layer, liquid epoxy
-
30–50 years: 3PE, dual-layer FBE, 3PP
-
50+ years: 3PE + CP, CWC + CP
