Flexalen 600 single line has been developed as a highly practical solution for district heating, cooling and potable water networks of any scale. As the most flexible pre-insulated pipe system on the market, network implementation is achieved in no time and at minimal hassle, while ensuring durable performance over a long lifetime.

High flexibility to minimize installation time and cost

The high flexibility of our Flexalen pre-insulated single line allows for highly efficient network implementation:

  • Optimal routing, uncomplicated by obstacles (trees, underground constructions, buildings, etc)
  • Minimal disturbance to the built environment
  • Limited number of welds required
  • High network efficiency: less angles allow higher flow speed, higher load capacity and smaller pipe diameters

Easy and sustainably efficient pre-insulated pipes

With a single flexible polybutene medium pipe, efficient polyolefin foam insulation and protective corrugated HDPE outer case, the Flexalen 600 single line pre-insulated pipe system is an ideal solution for both small and large-scale networks. It effectively tackles any installation routing and time restrictions, while ensuring durable performance for decades to come as a Cradle to Cradle Certified™ Silver pre-insulated pipe system.

Assortment

Flexalen 600 single lines are available in various dimensions, from OD 25 up to 90mm with an oxygen barrier on the polybutene medium pipe, and up to OD 125mm without oxygen barrier. Different insulation thicknesses are available. All Flexalen pre-insulated pipes are delivered in coil up to 300m (depending on diameter). Custom lengths are available upon request.

Heat loss tests are performed on different samples of the Thermaflex Flexalen 600 series and one ST-PUR-PE sample with the Thermaflex heat loss equipment and at two recognized test facilities, both using different test methods. The results of the institute using the same, guarded end method comply with the Thermaflex heat loss equipment’s results. The results of the institute using the calculated end method differ considerably from the Thermaflex results. In this paper a comparison of these methods and results and a verification of the Thermaflex heat loss equipment is given.
