Pipe in PPU insulation (polyurethane foam)

STEEL PIPES AND FASHIONED PIPES WITH PENOPOLIURETAN HEAT INSULATION WITH PROTECTIVE COATING. This standard applies to steel pipes and fittings with thermal insulation made of polyurethane foam (PU) in a protective sheath: in polyethylene (PE) jacket, designed for underground laying of heat networks (channelless or in non-passable and semi-passable channels), or in steel galvanised (OC) jacket - in passable channels or tunnels, as well as for above-ground laying (hereinafter - insulated pipes and fittings), operating with the following design pa- parameters of the heat carrier (superheated water): working pressure according to the project and temperature not more than 150 eC within the schedule of qualitative-quantitative regulation of heat supply 150 C -70 C
