Abstract

A method of manufacturing a shrouded pipe comprising an inner pipe section for providing a primary fluid path and an outer pipe section for enclosing the inner pipe section to provide a secondary fluid path. The method includes opening the outer pipe section by separating first and second longitudinal edges which split the outer pipe section along a longitudinal line, assembling the outer pipe section with the inner pipe section by passing the inner pipe section between the separated first and second longitudinal edges, and closing the outer pipe section by bringing the first and second longitudinal edges together and joining the first and second longitudinal edges together. An advantage of this method is that close manufacturing tolerances can be achieved without a complex or difficult assembly process.
