Abstract

1482661 Insulated pipes RAKENNUSMUOVI OY 25 July 1974 32823/74 Heading F2P [Also in Division B5] An insulated conduit comprises one or more tubes 2 surrounded by a foamed plastics insulation 3 extruded simultaneously with an outer plastics sheath 4 (see Divisions B4-B5). A single tube, Fig. 3 (not shown) may be provided with the insulation and with the sheath which are extruded from annular orifices or the insulated conduit may comprise the Fig. 4 or Fig. 5 section, comprising a plurality of tubes 2 within the same sheath 4. The tube or tubes 2 may be of metal, or cardboard, or of extruded plastics.
