Polyethylene is recognised by clients and engineering consultants alike as the ideal pipe material for many pressure and non-pressure applications from water distribution to gravity sewers, rehabilitation projects, manholes, as well as marine pipeline applications.

Recognising client’s needs for large diameter, lightweight, plastic low-pressure pipes and fittings, KWH Pipe Ltd developed WEHOLITE, a pipe constructed using a patented structured wall process, making it possible to manufacture large diameter plastic pipes up to 3,500 mm.

WEHOLITE pipe represents the latest advances in both material and manufacturing technology. Its unique structure can offer a range of pipe sizes and ring stiffnesses, depending on customer requirements. Raw material properties and product technology have been combined to provide a lightweight engineered pipe for various applications in municipal, industrial, road constructions, rehabilitation and marine pipeline applications.

WEHOLITE provides all the technical advantages of equivalent polyethylene solid wall pipes but with substantial savings in weight combining greater ease of installation with increased cost effectiveness.

WEHOLITE is today manufactured globally by KWH in Finland as well as in Sweden, Poland, Portugal, USA, Canada, Malaysia and Thailand as well as granting several manufacturing licenses around the world.
