Efficient protection against the freezing of both water and sewage pipes

Ground-based installations, and water and drainage pipes installed above the soil frost limit, require extra protection against freezing. The Wehoarctic piping system is made of PE, PP and PVC flow pipes. One or more cable profiles can be installed on the outer surface of the flow pipe, so that the elements can be equipped with auxiliary heating. In addition to the pipes, the system includes angled stretches of pipe, branches, contractions, wells, valves and fittings. Polyethylene Wehoarctic tubes can be installed either in the ground or in the air. Galvanized Wehoarctic tubes are intended for air installations only. As a special application, the pipes can be manufactured using PVC, PP, GRP or PVDF flow pipes, and an acid-proof spiro or steel shell.


Advantages of PUR water and sewage pipes

  • PUR insulation has low k-value, mechanical strength and a fast-fitting structure
  • The insulation makes it possible to fasten the outermost layer of the pipe to avoid cold bridging and possible leakage points
  • Units that are to be installed in the air can also be supplied with a galvanized or painted Spiro protective shell, which enables the element to blend well into the environment
  • Using a self-adjusting cable does not pose any risk of overheating, as the power of the cable is adjusted to suit the pipe temperature
