Pipes Repair

FRP as a Retrofitting Solution for Pipes Repair

Deteriorated and leaking pipes are a major concern for pipeline owners and operators. FRP products offer unique solutions particularly when strengthening existing pipelines are required. Most of these techniques are performed as trenchless, requiring zero or minimal excavation.

Thin sheets of FRP with a thickness of approximately 0.05 inch (1.3 mm) can be applied to the outside or inside surface of the pipe similar to wallpaper to strengthen the pipe. These materials cure within a day and reach a tensile strength three times that of steel. Afzir engineers will determine the number and orientation of fibers in each layer of the FRP fabric and will provide engineering drawings for such repairs.

Features & Benefits

Advantages of repair of pipes with FRP include:

  • Most repairs are trenchless, requiring zero or minimal excavation
  • Can increase the pressure rating of the pipe significantly
  • Repairs can be done internally or externally
  • Minimal increase in wall thickness (typically ¼ inch (5mm))
  • The smooth FRP lining will improve flow capacity of the pipe
  • Repairs are fast with minimal downtime
  • Ideal for spot repair of only damaged areas
