Key Features
Corrosion Resistance: High-density polyethylene provides excellent resistance to rust, galvanic corrosion, and many aggressive soil conditions.
Environmental Protection: Multi-layer construction can help limit fuel permeation and support compliance with applicable environmental requirements.
High Flexibility & Ground Movement Resistance: Flexible PE construction accommodates ground settlement, seismic movement, and surface loads with reduced risk of cracking when properly designed and installed.
Electrofusion Jointing: Electrofusion technology creates strong, sealed connections between compatible pipes and fittings, providing reliable long-term joint integrity.
Applications
Retail Fuel Stations: Underground fuel lines connecting storage tanks with dispensers.
Commercial Fleet Depots: Fuel distribution networks for private and municipal fueling facilities.

FAQ
Q: Why is PE 100-RC preferred over traditional carbon steel for underground fuel pipelines?
A: PE 100-RC does not corrode through electrochemical mechanisms like steel and offers high resistance to rust and many aggressive soil conditions. Additionally, it provides enhanced resistance to slow crack growth and greater flexibility for accommodating ground settlement, which can help reduce installation and lifecycle maintenance requirements.
Q: Can your PE pipelines handle modern alternative fuels like high-blend ethanol (E85) and biodiesel (B100)?
A: Qualified PE pipeline configurations can be designed for selected alternative fuels, including certain ethanol blends and biodiesel. Compatibility depends on the PE compound, barrier structure, fuel composition, temperature, pressure, and applicable standards. Specific fuel compatibility should be confirmed for each application.
Q: What specialized tools are required to install electrofusion PE pipes on-site?
A: Basic installation requires an approved mechanical pipe cutter, a professional rotary pipe scraper for removing the oxidized outer layer prior to welding, suitable cleaning wipes, pipe alignment clamps to keep joints stable, and a compatible electrofusion control box. Barcode-based welding parameters may be used where specified by the fitting manufacturer.
Q: How do you prevent fuel vapors and hydrocarbons from permeating through the pipe wall into the soil?
A: Qualified fuel-grade pipes may utilize a multi-layer structure incorporating an EVOH barrier layer to reduce hydrocarbon permeation. Actual permeation performance depends on the pipe construction, fuel type, temperature, pressure, and applicable test standards, and should be verified for the specific application.
Q: What is the typical operating lifespan of an underground PE fuel pipeline system?
A: When correctly designed, installed, and operated within specified pressure, temperature, and fuel-compatibility limits and in accordance with applicable industry practices, PE pipeline systems can be designed for a service life of 50 years or more. Actual service life depends on installation quality, operating conditions, material selection, and environmental factors.
Q: Can these PE pipes be connected to existing steel infrastructure or metallic dispensers?
A: Yes. We supply factory-manufactured mechanical transition fittings (PE-to-Steel) with suitable stainless steel or brass threaded/flanged connections. These provide a secure mechanical interface between the polyethylene pipeline network and compatible metallic equipment such as pumps, shear valves, and dispensers.
Q: What documentation is provided with each shipment for regulatory and permitting purposes?
A: Each shipment can include a quality documentation package containing material test reports (MTRs), raw material batch certificates, applicable pressure or performance test records, conformity documentation, and traceability information matching the physical pipe markings. Specific certifications and documentation depend on the product configuration and target market.
