Weholite is known world-over as the preferred structured wall pipe solution for various applications, from water distribution to gravity sewers, rehabilitation projects and manholes to marine pipeline applications. Now Marley Pipe Systems is bringing this renowned pipe system into the South African market with license to manufacture from Uponor Infra (formerly KWH Pipe)
Recognising demands for a lightweight, low pressure, large diameter pipe with fittings, Weholite represents the latest technology in both material and manufacturing. Its unique structure offers a range of ring stiffness’s and pipe diameters from 280mm up to a massive 3500mm. Weholite is manufactured in Finland, Sweden, Poland, South Africa, the United Kingdom, Canada, Malaysia, Oman, Iceland, Italy, Chile, Japan and Thailand and is steadily gaining ever wider acceptance in other countries around the globe.Owing to its light weight, Weholite provides for easy installation, even in complex installations where challenging conditions are presented, often removing the need for heavy lifting equipment and reducing health and safety risks. This, combined with efficient transportation and superior loading capacity, also means that the carbon footprint of Weholite is significantly lower compared to traditional materials.
The pipe design allows for a minimum design life of 50 years under specified design and installation parameters and the material selection process is the same as that used for pressure pipe applications. Research has shown that the service life of Weholite is 50% greater than concrete in stormwater applications, and at least 100% greater than concrete in corrosive applications. Weholite pipes are designed, manufactured and installed in accordance with Uponor Infra and Marley internal standards which conform to EN 13476 and SANS 21138, and form part of an SABS ISO 9001:2000 quality management system.
