Thermally insulated corrugated conduit
10220551 · 2019-03-05 · ·

The invention relates to a corrugated, thermally insulated conduit for fluids, e.g. for district heating networks, wherein at least one medium pipe (2) made of plastic or metal is surrounded by a thermal insulation layer (14), consisting of a polyurethane foam for example. The corrugation (25, 26) of the outer jacket (15) made of plastic is formed such that both the corrugation valleys (25) and the corrugation peaks (26) are round, particularly circular. In addition, the corrugation is dimensioned such that the corrugation depth T lies in a range of 4.5 mm to 8 mm for a conduit outer diameter range of 63 mm to 202 mm. This shaping and dimensioning of the conduit results in very good flexibility and thus the ability to roll up the pipe for the transport thereof.
