Simple Installation

The UPP electrofusion welding process is safe and simple to complete in any climate and virtually any weather condition.
An installer simply prepares the components, fits them together attaching welder leads to the fitting, and then presses a single button on the welding unit to initiate the process.
The welder unit itself calculates the exact settings required to complete the weld, regardless of the pipework diameter or temperature, leaving no settings for the installer to input.

Electrofusion Welding

At the heart of the UPP pipework system is the highly efficient electrofusion welding process that connects pipe, fittings, seals and containment to create a seamless direct burial pipework system.
The welding process uses the lightweight, portable UPP electrofusion welder unit to form the strongest of assemblies, which is easily and quickly carried out - even in confined spaces.

With installations in over 150 countries to its credit, the UPP pipework system boasts a sterling safety record.
Thousands of trouble-free existing installations around the world, some of which more than 30 years old, speak to the reliability of this non-conductive pipework system.
The proven track record of performing effectively in some of the world’s harshest conditions speaks for itself.

UPP pipe features an innovative clear inner lining made of natural EVOH resin to provide maximum pipe strength and superior vapour permeation and hydrocarbon barrier qualities.
UPP pipe is the first to receive an exception Class T1 temperature rating with its EN14125 approval, a true testament to its strength.

The end of a piping run can be fitted with a wide variety of termination fittings to accommodate any application.
UPP termination fittings feature an overmolded design which permanently bonds the metal threads of the fitting to an HDPE pipe segment.
This allows the same electrofusion process to create a liquid tight bond between the pipework and metal termination fitting.
