Abstract

An insulated pipe comprises an inner fluid pipe (1), an outer jacket pipe (3), as well as an insulation (5, 6, 7) arranged therebetween. The insulation consists of a plurality of insulating bag units (5, 6), each having a flexible bag wrapping enclosing a high-insulating, fine-grained powder material in a moisture- and vacuum-proof manner, the insulating bag units substantially filling the space between the fluid pipe and the jacket pipe, and of an insulating foam (7) filling the interspaces (9, 10, 11) between the insulating bag units as well as between the latter and the two pipes.
