Flexible pipe systems can significantly reduce the costs for developing supply areas. System manufacturers offer various pipe systems using different materials for the water-bearing medium pipe, the heat insulation and the jacket pipe. Particularly important are

  • PE-X (crosslinked Polyethylene) and PB (Polybutene) medium pipes
  • High-grade steel medium pipes
  • Mild steel medium pipes
  • Copper medium pipes


We actively contributed our extensive knowledge of planning and application to the preparation of the AGFW guidelines FW 420, parts 1, 2, 3 and 5. Design and dimensioning are influenced by the very diverse technical characteristics of the various systems. Local characteristicts for the pipe laying (ground water), oxygen and steam diffusion as well as jointing techniques have to be considered. Another important aspect is the suitability for long-term operation.
