GRP pipe systems and solutions

Glass fiber reinforced plastics (GRP) are a composite consisting of at least two different materials. The benefits of each material are united to achieve an overall effect.


A binder or matrix and reinforcing material is commonly used to combine the physically differing raw materials. Their molecules do not bond but they form a composite by joining their boundary layers. What is important is that the constituents are compatible in terms of properties and processing. This technology originated in the aviation and marine industry where particularly light high-performance materials are required.

Advantages – why engineers choose Amiblu GRP pipes

  • Expected service life
    Amiblu pipes have an expected service life of more than 150 years.
  • Corrosion-free
    Amiblu pipes need no coating or anti-corrosion treatment. The pipes are manufactured from inherently corrosion-resistant materials, thus outperforming steel, ductile iron, and steel-reinforced pipes that require corrosion protection.
  • UV-resistant
    Amiblu pipes are resistant to UV light.
  • Acid resistant
    Amiblu pipes have an extraordinary resistance against acid and chemicals. The unique resistance of Amiblu pipes is ensured by careful consideration of all raw materials, the pipe design and production process. Amiblu pipes resist the sulfuric acids that build up in sewers. They resist the actions of ground salts and salty waters. Amiblu pipes may also be used in other chemically demanding applications.
  • Lightweight design
    miblu GRP pipes are lighter than ductile iron, steel, concrete and most non-reinforced plastic pipes. This makes transportation less expensive, and less expensive installation equipment can be used. Their light weight enables the pipes to be easily transported and handled in remote and hardly accessible areas. Amiblu pipes can be nested, meaning that smaller pipes can be transported inside larger pipes, thus reducing the cost of transportation.

Environmental impact of Amiblu pipes

Amiblu pipes have a low carbon footprint compared to other pipe materials. This has been confirmed by external bodies and universities.

  • Comparison to other materials
    An independent study conducted at The Norwegian University of Life Sciences in 2012 concludes that GRP pipes have a minimal negative environmental impact compared to other pipe materials. The main reason for this is the material efficiency.
  • Energy-efficient in operation
    The smooth bore and good flow characteristics of Amiblu pipes reduce the amount of energy used for pumping. In penstocks, it increases the energy output.
  • Low energy consumption in production
    The amount of energy used in the production of Amiblu pipes is less than what is required for most other pipe materials.
  • Transport efficiency
    Lightweight design combined with the fact that Amiblu pipes can be nested during transportation lead to lower carbon emissions from pipe transportation.
  • Recyclable
    Amiblu pipes are recyclable. The Federation of Reinforced Plastics in Germany recommends that GRP pipes are used in cement production.
