A rigid, pre-insulated glass-reinforced epoxy (GRE) pipe system capable of operating at temperatures and pressures previously only achievable with steel systems, it offers outstanding thermal performance coupled with exceptional levels of reliability.
A composite pipe manufactured from helical-wound glass fibre reinforced epoxy material that is designed for use in heating and cooling networks. Offering a operational service life of 50+ years when operating at 95°C and 10 bar, the service pipe will accommodate pressures of up to 16 bar and details of service life at other temperature and pressure combinations can be supplied on request.
Tough Outer Casing
Manufactured in HDPE to the requirements of the EN253 standards, the tough and resilient outer casing enables the pipe to be buried directly in the ground.
Complete System
Hiline GRE has a comprehensive range of pre-fabricated bends, tees, fittings and accessories that enable it to be adapted to meet all possible configurations – including transitions to other types of pre-insulated pipe systems – such as Hiline Steel or Hiline Flex.
Hiline GRE can be offered as off-site pre-fabricated fittings and spool assemblies to meet a client’s bespoke requirements – significantly reducing installation time and cost
Robust and Adaptable Joints
The Hiline GRE service pipe is joined by means of an adhesive-bonded taper socket and spigot technique that provides secure and reliable connections that will exceed the life expectancy of the pipe system. The HDPE outer casing can be joined using the proven Hiline range of wrap-around heatshrink or electro-fusion couplings to ensure the very tightest of joints to protect against the ingress of ground water.
Trace Heating and Leak Detection Options
Hiline GRE is available with the option of integrated trace heating cables to protect the media temperate and leak detection systems that warn of moisture ingress into the insulation.
