Abstract: An insulated pipeline having spaced sections of heat-insulating material held between a continuous corrosion-resistant coating on the pipe and an outer protective jacket, thereby to provide a flexible composite which renders the pipeline resistant to mechanical and chemical attack while provided heat insulation for the pipeline in a manner which allows the pipeline to flex, for example during laying. The pipeline is preferably in the form of a continuous protective matrix bonded to the pipe and enveloping individual sections of the heat-insulating material.

Abstract: The clamp of the invention comprises a strip of flexible material formed at the ends with tongues which can be engaged with one another when the clamp is fitted around a tubular or bar-like object. One end is formed with at least one set of three tongues consisting of a short tongue flanked by two long tongues the tips of the long tongues being bridged by a fixed bar and the other end is formed with at least one tongue engageable over the bar and under the short tongue of the tongues of the other end. The strip of flexible material may consist of two portions hinged to one another.
