You are...

Are you a pipe and fitting manufacturer, a contractor or working in a network company? Or are you someone who seek answers to enquiries regarding plastic gas piping systems? We can help you further with our expertise. 

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

You can rely on years of expertise

Kiwa is active in securing the quality, safety and reliability of the traditional PE and PVC gas distribution piping systems since the introduction of these materials. But we are also very active regarding more recently introduced and new polymer materials for gas distribution, like PA (polyamide), PE100 RC. And numerous innovative multilayer and composite piping systems, and alternative materials for gas fittings (e.g.POM, PPSU, PVDF). We can also help you with our knowledge of polymer materials. These materials are  more and more used for indoor gas piping systems. For already more than a decade Kiwa has experience with PEX and multilayer piping systems, connected with mechanical metal fittings or plastic fittings (PPSU, PVDF).
