ABSTRACT:
An insulated pipe structure suitable for use in an undersea pipeline comprises, intermediate its ends, an inner pipe (11) for serving as a conduit for fluid flowing through the pipe structure, thermally insulating material (3) extending around the inner pipe and an outer shell (2) extending around the insulating material (3). At each of the ends of the pipe structure the inner pipe is connected to the outer shell by a thermally insulating connecting element (4) which is secured to the inner pipe (11) at least partly by virtue of adhesive forces between the inner pipe (11) and the connecting element (4). The thermally insulating connecting element (4) and the outer shell (2) together protect the insulating material (3) from water ingress and from ambient pressure.
