Weholite is a high quality structured-wall pipe with smooth internal and external surfaces. Weholite pipe is manufactured by spiral welding PE- or PP-profiles. The Weholite product range is a complete pipework system for conveying liquids or air, underground, under water or above ground. 

Weholite is a patented pipe construction making it possible to manufacture pipes in diameters up to 3.5m. Weholite provides all the technical advantages of equivalent PE solid wall pipes but with substantial savings in weight combining greater ease of installation with increased cost effectiveness. Installation is quick and reliable, with the pipes easily transported to the job-site, even in poor ground conditions. Weholite pipes have a natural ability to "flex", which enables them to adjust to different loading conditions, vibrations, stress and soil movements without causing damage to the pipe.

Weholite is manufactured in sizes ranging from 300 to 3500 mm internal diameter, and can be supplied in ring stiffness classes up to 8kN/m2. Pipe lengths are normally 12 - 18m. Various jointing methods are available to suit different application requirements. The Weholite pipe can also be designed and manufactured for low-pressure applications up to 2 bar internal pressure.

Weholite can be used for many different applications, including municipal sanitary sewers, wastewater treatment plant biofilters, low-pressure hydroelectric penstocks, irrigation, water conveyance, culverts, storm drainage systems, storm water detention systems, manholes, and tanks. Because of its durability, lightness and outstanding chemical resistance, Weholite can also be used for a number of industrial applications.
