GRE Pipe Systems
Glass‑reinforced epoxy pipes for demanding environments
Up to
Up to
Amiblu delivers complete GRE system solutions engineered for high‑demand environments such as district heating networks, oil and gas refineries, and data centres. GRE (Glass-Reinforced Epoxy) combines high‑strength glass fibres with a thermosetting epoxy resin matrix, providing exceptional mechanical performance, corrosion resistance, and thermal stability.
Fully resistant to internal and external corrosion, GRE pipes perform reliably in aggressive, humid, and high‑temperature applications. Their filament‑wound epoxy structure ensures high pressure resistance, low friction losses, and long‑term mechanical integrity at temperatures up to 120 °C. These properties ensure stable, leak‑tight operation and long‑lasting performance in the most demanding environments.
GRE solutions for demanding applications
Amiblu is the only manufacturer in Europe offering a complete GRE portfolio, including uniaxial and biaxial piping, trenchless pipe systems, and a wide range of joints and fittings. We provide fully customised solutions tailored to specific load cases and project requirements for diameters from DN 25 to DN 3200.
Amiblu high-performance GRE pipe systems are available for both buried and above-ground installations and are ideal for:
- Oil & gas networks (flowlines, injection lines, firewater systems)
- District cooling & heating systems
- Seawater applications (desalination, ballast systems)
- Water & wastewater infrastructure
- Industrial & chemical processing
Why choose Amiblu GRE
pipe systems
Amiblu GRE pipe systems are suitable for elevated operating temperatures of up to 120 °C and are engineered to withstand pressure and operational stresses reliably through enhanced material performance.
GRE pipes are fully resistant to acids, alkalis, seawater, and aggressive chemicals. They do not corrode or suffer from electrochemical degradation, eliminating the need for coatings or cathodic protection.
The smooth internal surface reduces friction losses, enabling higher flow capacity and lower pumping energy throughout the entire service life.
Designed for a service life of several decades, even in harsh environments, Amiblu GRE pipe systems require minimal maintenance.
Proven GRE solutions in
critical infrastructure
Amiblu GRE pipe systems support reliable operation in the most demanding energy projects. From modernising ageing district heating networks to enabling strategic LNG import infrastructure, these reference projects demonstrate how GRE delivers long‑term performance, corrosion resistance, and operational reliability under challenging thermal, mechanical, and environmental conditions.
Amiblu GRE pipes upgrade Lisbon's district heating and cooling network
Amiblu supplied GRE piping systems and engineering services to refurbish the ageing district heating and cooling network beneath Lisbon’s Parque das Nações. The original steel pipelines, affected by corrosion and increasing maintenance requirements, were replaced with corrosion‑resistant epoxy pipes to ensure long‑term reliability without disrupting activity above ground.
Amiblu GRE pipelines support Germany’s LNG terminal in Brunsbüttel
Amiblu delivered high‑performance GRE solutions for Germany’s first land‑based LNG import terminal in Brunsbüttel, a cornerstone project for strengthening national and European energy security. Selected for its expertise in composite piping, Amiblu supplied a robust and corrosion‑resistant solution capable of withstanding harsh environmental and operational conditions.
