Starline - Model HPL-W -Drinking Water Transport Pipelines
Our starline®HPL-W technology is used for the rehabilitation of drinking water transport pipelines and long distance pipelines. The fabric hose and adhesive are tested for pipes with a diameter of DN 100 up to DN 600 and with maximum operating pressures of 40 bar. Up to eight hours processing time allow very long sections to be rehabilitated. No additional heating is required for the curing process.
At the heart of the starline®HPL special technology is the self-advancing pressure drum on crawler tracks, which is perfectly suited to uneven terrain and high quality surfaces. First, the specified quantity of adhesive is applied evenly to the fabric hose in a climatised application container. This means that lengths of up 600m can be treated, irrespective of the diameter. As small cleaning pits are only needed at a maximum distance of 180 m, there is less than 10% earthwork.
Existing and future pitting corrosion of up to 50 mm diameter can be removed efficiently, fast and sustainably, and the operating safety and drinking water hygiene can be restored. In addition, normal tools can be used to drill into the pipe in future with no problem.
