The Gold Standard
in Fuel Transmission.
Unrivaled safety, durability, and installation efficiency with our advanced multi-layer double-wall composite piping systems. Engineered for a future-proof fuel infrastructure.
The Science of Multi-Layer Safety
Molecularly bonded layers engineered to provide an impenetrable barrier and lifetime structural stability.
1 PE-RT Internal Core
High-performance polyethylene with enhanced temperature resistance, ensuring smooth fluid dynamics and pressure stability.
2 EVOH Barrier Shield
The core intelligence of the pipe. An ultra-thin Ethylene Vinyl Alcohol layer that provides zero-permeation of hydrocarbons.
3 Molecular Adhesive Layer
Specially formulated tie-layers that create an inseparable bond between the barrier and the structural polymers.
4 Anti-Static Outer Skin
A reinforced external layer integrated with carbon-black conductive technology to safely dissipate static electricity (ATEX compliant).
90% Faster Installation
Redefining petrol station construction with high-flexibility coils and automated fusion technology.
Continuous Coils
Delivered in long continuous coils (up to 100m+), eliminating 90% of joints and potential leak points compared to traditional rigid pipes.
Smart Fusion
Automated electro-fusion welding creates a homogenous molecular bond in minutes, ensuring a lifetime of zero-leakage performance.
Trench Efficiency
The flexible radius allows for direct burial without the need for complex elbows, drastically reducing trench width and excavation costs.

Application Scenarios
High-Traffic Service Stations
In busy urban hubs, downtime is not an option. Our composite pipes provide seamless flow with zero maintenance, allowing for 24/7 refueling operations without the risk of underground corrosion.
Arctic & Cold Climate Projects
Standard pipes often become brittle in sub-zero temperatures. Our PE-RT based composite system remains flexible and pressure-resistant down to -40°C, ensuring integrity in frozen soils.
Coastal Terminals & Marinas
Saltwater and high humidity accelerate the rust in steel pipes. Our non-metallic composite structure is 100% rust-proof, making it ideal for seaside fueling and harsh industrial chemical transfer.
Expert Insights & Maintenance

Is the pipe compatible with high-ethanol (E85) or Methanol fuels?
What special tools are required for electro-fusion welding?
How does the 30-year warranty handle soil movement?
Maintenance Pro-Tip
We recommend a semi-annual inspection of the sump entry boots and a quick check of the leak detection console. Since the pipe itself is non-corrosive, the primary focus is ensuring the connection points remain watertight and free of external debris.
Complete System Synergy
Our composite pipes work in harmony with advanced containment accessories for an absolute leak-proof system.
Transmission Pipe
Heavy-duty, high-capacity lines designed for main fuel transfer networks across larger sites.
Manhole Wells
Subsurface HDPE housings that provide a dry, secure environment for pipe terminations.
Entry Boots
Flexible Nitrile seals that guarantee 100% airtight penetration through sump walls.
Dispenser Sumps
Secondary containment units located directly beneath dispensers to capture potential leaks.
