You are...

If you are a pipe and fitting manufacturer, a contractor or working in a network company. Or if you are someone who seek answers to enquiries regarding plastic water piping systems, then our Kiwa experts can offer you relevant services in your field.

Plastic pipe materials have already been proven to be safe and reliable in water distribution systems for many decades. PE (polyethylene) is worldwide the most well known material for plastic water pipes and fittings. And PVC is also being successfully used for water distribution pipes and mechanical fittings since a long time.

Safety and reliability

Also in water (indoor) installations, plastic pipe materials have been functioning safely and reliably for many decades. For indoor water pipes various materials are used such as PE-X, PB,PP-R,PE-RT and PVC-C. Nowadays metal and plastic multilayer pipes with barrier properties are widely used having the properties required for drinking water, underfloor heating and radiator heating in one pipe. For the fittings, materials like brass are more and more replaced by common or engineering plastics such as PVDF and PPSU.

Kiwa is active in securing the quality, safety and reliability of these traditional materials and new piping systems since the introduction of these materials.
