A global marketing partnership between Dow Chemical Co. and Switzerland-based RS Technik is promoting a solution for self-renewing pressure pipes.
Co-operating with US-based Inland Pipe Rehabilitation, the companies will be marketing their NSF/ANSI 61-certifiied pipe-in-pipe system for immediate installation.
The RS BlueLine pipe renewal technology from RS Technik consists of a fiberglass composite tube, made using Dow custom-formulated resin, which is installed into damaged water and transmission mains. A new pipe is created inside the existing pipe by means of cured-in-place-pipe (CIPP) technology. This saves time and money over the usual option of excavation and full replacement.
"Losses in drinking water distribution is a major global problem with infrastructure aging and leaks difficult to detect and costly to repair. With our expertise in material science, and working with RS Technik, we deliver a breakthrough solution for this critical global challenge," said Jon Penrice, global business director at Dow Formulated Systems.
RS BlueLine technology is certified to NSF/ANSI 61 by NSF International, the independent global public health and safety certification organization, and German DVGW regulation W270. This means it can be used in the renewal of all potable water pipes, including drinking water distribution mains and transmission lines from 150mm to 1.2m diameters. The static ability of the RS BlueLine system can carry a long-term inner pressure up to 16 bars without the support of the existing pipe, and replaces the existing pipe with all its functions.
