Abstract
An elongated pre-insulated pipe assembly for fluid transfer, the pipe assembly having a longitudinal center axis (x) and comprising: a center insulator profile made of thermally insulating foamed plastics, the center insulator profile having a circular cross-section and being concentric in relation to the center axis (x), the center insulator profile comprising at least two longitudinally extending channels formed inside an periphery of the center insulator profile and each channel being adapted to receive one flow pipe, at least two flow pipes made of plastics, each one of the flow pipes being inserted inside the channel of the center insulator profile, at least one insulation layer made of thermally insulating foamed plastics arranged to enclose the center insulator profile, and an outer jacket made of plastics to enclose the at least one insulation layer. At least one channel of the center insulator profile and the flow pipe inserted in said channel are disposed inside the center insulator profile at a distance from the outer periphery of the center insulator profile and closer to the center axis (x) than other channels and the flow pipe arranged in said other channel.
