Heat-Tite& 2 YRS.Insulation materials in district heating pipes

In paper I, the diffusion characteristics of cell gases in cyclopentane blown PUR foam and in the high density polyethylene (HDPE) casing surrounding the foam in district heating pipes are determined. This is a type of pipe commonly used today. In paper II, the mass transport properties of a new blowing agent, HFC-365mfc, is studied. The DistrictPolyurethane Foam Heat-insulating Steel Pipe Hebei hdpe pipe casing PU foam thermal insulation water pipingThermal insulation Direct buried pipe can be directly buried in permafrost 0.6-1.2 meters, (So people used to call it a direct-buried insulation pipe or a prefabricated insulation pipe)heat loss can be reduced by more than 40% than ordinary pipelines, working life is 3-5 times longer than other thermal insulation materials, life can reach 30- 50 years; Quality meets or exceeds Chinese industry hdpe pipe casing PU foam thermal insulation water piping

Fintherm Twins is used for heat distribution. These pre-insulated pipes are manufactured from steel pipes insulated with hard polyurethane foam covered with a layer of polyethylene. The insulation is applied to the supply and
