Weholite is used in a variety of pipeline applications from simple road or rail culverts to more demanding inter-process pipework on sewerage treatment plants and for offsite build components.

The uniqueness of the Weholite production process means that pipes can be run in any length from 300mm to 30m in one piece. It is one of the few polyethylene pipes in the world that can be produced in dimensions larger than two metres and can be supplied in ring stiffness classes from 2 to 8kN/m2.

  • Wide range of sizes
  • Lightweight
  • Resistant to H2S
  • Ultra-low roughness coefficient
  • Abrasion-resistant
  • Multiple jointing systems
  • Compliant with BS EN 13476
  • Available in panel form

Weholite pipes can also be used for hydroelectric pipelines and intake structures, anaerobic digestion and air vent systems, and as storage, contact and inter-process pipework for drinking water applications

Manufacture & certifications

Weholite pipes are manufactured and certified to meet the material and performance requirements of BS EN 13476: 2007 (Part 1-3) Plastic Piping Systems for Non-Pressure Underground Drainage and Sewerage.

Weholite pipes have attained certification for DWI Regulation 31 Reference no DWI 56.4.513 “Approved for use in public water supplies” and are WRAS-approved.
