The foundation everything else builds on
Walk through any modern pipe-coating plant in the world and you'll find at least one FBE line. Fusion-bonded epoxy is the most-tested, most-specified, most-installed pipeline coating in industrial history. It works as a stand-alone external coat for moderate-environment pipelines, it's the primer layer beneath every 3LPE and 3LPP system we make, and it's the standard for rebar, valves, fittings and downhole tubing.
We run dedicated FBE production lines for pipes 1/2"-60" in diameter, plus separate booths for rebar and odd-shaped fittings. Every line is electrostatic-spray with IR-controlled pre-heat and continuous QC.
What FBE actually is
A one-part thermosetting epoxy powder. The base resin is bisphenol-A or novolac, depending on the temperature grade. Curing agents, pigments, fillers and flow-control additives complete the formulation. When the powder hits a steel pipe pre-heated to 220-240 °C, the particles melt, flow, gel and chemically cross-link — locking onto the steel as a hard, dense, tightly-adhered film typically 350-500 µm thick. The whole gel-and-cure cycle takes about 3 minutes.
Where we use FBE
- Stand-alone external pipeline coatings for above-ground or moderate-buried applications
- Epoxy-coated rebar for highway bridges, ports, marine concrete structures
- Valves, flanges and pipe fittings — uniform film on complex shapes
- Internal lining of downhole tubing (phenolic-modified FBE for sour service)
- Primer layer for our 3LPE and 3LPP systems
- Subsea pipe sections under concrete weight coating

How we control quality
Every FBE-coated pipe leaves our facility with:
- Mill test certificate (MTC) traceability
- Pre-heat temperature log from IR pyrometer
- DFT measurements at no fewer than 4 points per metre
- 100% holiday detection at 5 V/µm
- 28-day cathodic disbondment coupon test results
- Cross-cut adhesion check on every batch
Third-party inspection by SGS, Bureau Veritas, TÜV or your nominated agency is available on request.
Common project questions
FBE alone or 3LPE — how do I decide? Above-ground refinery piping, rebar, fittings — FBE alone is sufficient and economical. Buried trunklines, deep water, rocky soil, directional drilling — go 3LPE. The two systems share the same FBE primer, so the underlying corrosion protection is identical; 3LPE just adds mechanical layers on top.
Maximum operating temperature? Standard FBE: 85 °C. High-temperature phenolic/novolac-modified FBE: up to 150 °C.
Can FBE be used inside pipes? Yes — phenolic-primer-modified FBE is the standard for downhole tubing in sour-service oil & gas, and for high-pressure water-injection lines.
