The patented wall structure of the Weholite pipe makes it possible to produce flexible and long-lasting lightweight PE pipes up to 3500 mm. Under normal operating conditions, the PE material is chemically resistant. Weholite does not rust or corrode due to chemical or electrical reactions in the soil. The material’s excellent abrasion resistance and flexibility make Weholite a truly multifunctional pipe that can be easily and quickly installed thanks to its lightweight construction.
