Abstract

In accordance with the present inventions there is provided a thermally insulated pipe for transporting fluids, being connectable to at least one further pipe. The pipe comprises an outer pipe wall and an inner pipe wall substantially parallel to the outer pipe wall and configured to contain a fluid within the pipe. The inner pipe wall comprises a body portion and a connection portion extending therefrom, a thermal insulation layer provided between the outer pipe wall and the body portion of the inner pipe wall, and at least one male joinable end. The male joinable end comprises the connection portion of the inner pipe wall which terminates in a connection component adapted to engage a connection component of a further pipe, and a transition region where the outer pipe wall tapers continuously inwardly to meet the connection portion of the inner pipe wall.
