Products:
PLX Single Wall Pipe System
Sizes: 32mm to 160mm standard
A high-performance single-wall fuel pipework solution used primarily for vent lines, vapour recovery and bulk fuel transfer. Manufactured from multi-layer polyethylene with an internal barrier layer to prevent permeation, it delivers long-term durability for below-ground applications in forecourts and industrial
PLX Close-Fit Secondary Contained Pipe System
Sizes: 32/40mm to 110/125mm
A secondary-contained pipework system designed to provide added environmental protection through continuous interstitial leak monitoring. Suitable for above- and below-ground installations, it offers enhanced safety while maintaining efficient installation and long-term system integrity in high-risk fuel environments.
PLX One-Weld Secondary Contained Fittings
Compatible sizes: 63/75mm & 110/125mm (Close-Fit systems)
An industry-first fitting solution that allows primary and secondary joints to be fused in a single electrofusion cycle. This dramatically reduces installation time while maintaining full secondary containment and leak detection capability, improving efficiency on complex or time-sensitive projects.
PLX Electrofusion Termination Fittings
Compatible sizes: 32mm to 125mm
Designed to terminate secondary-contained pipework into a single-wall connection without compromising containment. These compact fittings reduce excavation, installation steps and welding time while maintaining compliance with industry standards and monitoring requirements.
PLX Electrofusion Chamber Entry Fittings
Sizes: 32mm to 125mm
Multi-size adaptable options available
A secure electrofusion-welded solution for connecting fuel pipework directly into polyethylene chambers. With no rubber seals or gaskets, these fittings ensure a leak-free, long-term connection while maintaining pipe continuity into the chamber for maximum environmental protection.
PLX Blue AdBlue Pipe System
Single wall sizes: 32mm to 63mm
Secondary contained sizes: 32/40mm to 63/75mm
A purpose-built pipework system for AdBlue and DEF applications, designed to prevent contamination, chemical degradation and permeation. Suitable for forecourts, transport depots and fleet facilities requiring compliant AdBlue infrastructure with optional leak detection monitoring.
PLX Electrical Conduit Pipe System
Sizes: 32mm standard
Additional sizes available on request
An external-barrier electrical conduit featuring an integrated aluminium layer that prevents fuel and chemical ingress from contaminated ground conditions. Designed to protect conveyed cables in petrochemical, forecourt and industrial environments, offering superior durability over traditional conduit systems.
PLX Tools and Accessories
Supports all PLX sizes from 32mm to 400mm
A comprehensive range of specialist tools including pipe cutters, preparation tools, clamps, welding machines and chamber fittings. Designed to ensure correct installation, system integrity and long-term performance across all PLX pipework systems
Aliaxis UK Ltd has delivered PLX Fuel systems in forecourt applications for over 25 years means we are able to develop and specify solutions that provide high-performance protection against corrosion and permeation while being simple and easy to install.
The bulk fuelling requirements of transportation hubs can be diverse where reliability is of paramount importance. PLX fuel system, often in pipework, often in large diameter sizes has been used to supply fuel to marinas, airports, rail haulage yards and haulage distribution depots.
Sudden or prolonged loss of electrical power can be catastrophic for many business services so for extra security, oil powered emergency or uninterrupted power supplies (UPS) are, therefore installed for back-up power. PLX pipework is often installed to convey fuel oil to boilers, which in turn powers back-up generators.
Case Studies
Proven Performance Across Critical Environments
Aliaxis UK PLX Fuel systems are trusted worldwide in high-risk, high-demand fuel and infrastructure environments, delivering long-term safety, reliability and measurable installation efficiencies.
Protecting Electrical Cables in Forecourts
In a service station project in Rosebud, Australia, PLX Electrical Conduit was specified to protect electrical cabling from potential fuel spillages and contaminated ground conditions. Unlike traditional conduits with internal barriers, the PLX system prevents fuel ingress from the outside environment. Installers reported faster installation, improved rigidity and reduced movement once laid, significantly improving site efficiency and long-term protection.
Faster Forecourt Installation with One-Weld Technology
During the construction of a new service station in Pinvin, Worcestershire, PLX One-Weld fittings were used to reduce installation time and excavation requirements. By welding primary and secondary joints in a single fusion cycle, installers achieved time savings of up to 15 minutes per fitting, improving programme delivery without compromising safety or containment integrity.
Marina Fuel Transfer with Secondary Containment
At Lowestoft Haven Marina in the UK, PLX Close-Fit secondary-contained pipework was installed to safely convey marine fuel from storage tanks to dispensing pontoons. The system provided corrosion resistance, permeation protection and continuous leak detection, offering peace of mind in a sensitive marine environment while reducing long-term maintenance requirements.
AdBlue Infrastructure for Transport Depots
At the National Express Walsall Bus Depot, PLX Blue was selected as a dedicated solution for transferring AdBlue from storage tanks to dispensing points. The system ensured chemical compatibility, leak prevention and environmental protection, supporting fleet operations that depend on compliant and reliable AdBlue supply infrastructure.
Trusted Across Industries
PLX systems are widely used across:
- Forecourts and fuel retail
- Transport depots and fleet facilities
- Marinas and ports
- Rail and aviation infrastructure
- Data centres and hospitals
- Industrial and off-grid power installations
Each case study reinforces PLX fuel systems ability to deliver safe, compliant, long-life pipework solutions where operational continuity and environmental protection are non-negotiable.
