Renovation of overhead heat distribution systems insulation
The new method of renovation of the aboveground district heating networks is based on removing the old insulation from the existing steel pipe, covering this pipe with zinc plated metal sheet casing and then filling the resulting space between the steel pipe and the casing pipe with polyurethane foam applied with the use of the foam generator. The whole process can be performed directly on the building site.
