KWH Pipe offers gravity pipe systems for different applications. We produce gravity pipes made from polyethylene, polypropylene and PVC.

Polyethylene (PE) gravity pipes have outstanding performance advantages: joint tightness, flexibility, abrasion - and chemical resistance offers an extremely long life cycle. Polypropylene (PP) gravity pipes and fittings are designed and manufactured to meet climate related requirements in Nordic countries. PVC gravity pipes and fittings as well as PP gravity pipes and fittings are applicable for soil and waste discharge within the building structure, as well as for underground drainage and sewerage.
Weholite is an extremely versatile KWH Pipe product. It is a high-quality structured-wall gravity pipe made of PE or PP. 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.
WehoPropen HT/HT+ PP gravity pipes and fittings are applicable for soil and waste discharge within the building structure, as well as for underground drainage and sewerage.
