Pressure pipe rehabilitation for utility companies

Safe access to water, gas and oil in considerable parts rest on smaller and larger networks of pipelines. Water and gas even arrive in homes this way directly.

Use and time do not pass pipes by without a trace: Wear and deposits sooner or later push every pipe material to the limits of its durability.

With Primus Line® utility companies have a trenchless technology for rehabilitation at their disposal that facilitates a speedy recommissioning while only requiring little space and minimal machine employment.

This means shorter interruption of supply, less disruptions to traffic and a significantly lower environmental impact.

Primus Line® achieves a product life of at least 50 years.
