GRP Pipe & Fittings

Overview

GRP Pipe and fittings are manufactured using three composite materials – sand, glass fibre and thermosetting resins. Thanks to the way these materials are applied throughout the manufacturing process, GRP pipe offers the required pressure rating, structural strength, stiffness rating and chemical and abrasion resistance.


Product Standards: AS3571, ISO 10467, ISO 10639, AS/NZS3571, ISO25780

Key Features

  • Manufactured and Certified to AS3571
  • Extensive inventory available for immediate delivery
  • Suitable for water, sewer and industrial applications up to PN40
  • Lightweight, corrosion resistant and simple to install
  • Superior full face EPDM coupling system
  • 100+ year expected design life
  • No sleeving, coatings or cathodic protection required

More Information

Clover offer GRP products produced using either the Continuous Filament Winding (CFW) or Centrifugal Casting (CC) manufacturing process.

Typically, the CFW process leads to a more material efficient pressure pipe, ideally suited to high pressure applications such as water mains and sewer rising mains.

Alternatively, the CC process produces a pipe that is equipped with qualities for dealing with higher axial compressive loadings, making it an ideal solution for jacking pipe applications.

Although they vary in design and application, both methods produce a corrosion resistant pipe with superior strength and outstanding hydraulic properties.

GRP is highly chemical resistant and suitable for aggressive environments such as acid sulphate soils.
