Conductive GRE Pipes

Conductive GRE pipes are specialized fiberglass-reinforced epoxy lines engineered to safely convey flammable, non-conductive fluids by dissipating static electricity. They contain co-mingled conductive fibers (typically carbon with glass) throughout the wall, providing through-wall conductivity. This design prevents charge build-up when pumping fuels or solvents, substantially reducing ignition risk in oil & gas, aviation fuel, chemical and petrochemical systems. The pipes maintain the core benefits of GRE (lightweight, corrosion-resistant, high-strength) while adding an integrated static-dissipative function. Conductive GRE systems are often used in jet fuel and aviation fuel piping (military specs), bulk hydrocarbon handling, and high-purity chemical lines where grounding is critical.

Product Inquiry

Key Features

Conductive Filaments: High-strength carbon/glass composite fibers woven into the laminate provide uniform electrical conductivity.
Integrated Grounding: Inner-to-outer and end-to-end electrical continuity allows easy grounding of the pipe system.
Corrosion Resistance: Inherits GRE’s excellent resistance to acids, salts, and fuels, with no risk of metal corrosion.
Lightweight and Durable: Easier to install than metal. Suitable for buried or aboveground use without risk of electrochemical corrosion.
High Temperature Rating: Uses aromatic-amine-cured epoxy for toughness and heat resistance (typically up to ~100–120°C).
Reliable Jointing: Compatible with standard GRE couplings and flanges (but typically grounded at joints).

Benefits

Enhanced Safety: Prevents dangerous static sparks in volatile environments, meeting electrical dissipation safety codes.
No External Bond Wires Needed: Unlike plastic pipes that require external bonding, conductivity is built-in, simplifying installation.
Lower Maintenance: No corrosion or coating to maintain, and static-dissipative layer won’t wear off like a metal liner.
Regulatory Compliance: Often required or recommended by NFPA and API for fuel systems (e.g. MIL-P-29206A for jet fuel).
Versatility: Can replace metallic piping in hazardous areas, reducing risk of galvanic corrosion while ensuring ESD protection.

Applications

Jet Fuel and Aviation Fuel Systems: Primary lines and hydrant systems at airports or military bases.
Fuel Terminals and Depots: Fuel storage and transfer lines, where static discharge is a concern.
Chemical Processing: Handling of solvents, corrosive chemicals and any process where static ignition is hazardous.
Pharmaceutical & Electronics: High-purity lines where static must be controlled, but metallic pipes are not preferred.
Offshore Petrochemical: Bulk fluid transfer on platforms (e.g. jet fuel, kerosene) requiring both corrosion resistance and static safety.
