Abstract
A pipeline 100 comprising an outer rigid conduit 30, which is formed of a composite material, the composite material being arranged such that thermal expansion in the longitudinal direction is an effective longitudinal CTE from zero to about −/+10×10−6° K−1.
Claims7
A pipeline comprising
- a. a composite pipe formed of composite material configured to convey cryogenic material wherein the pipe has an effective longitudinal coefficient of thermal expansion (“CTE”) from about −10×10−6° K−1 to 0° K−1 and is not brittle at a cryogenic material temperature;
- and,
- b. an inner tubular structure surrounded by the composite pipe and comprising;
- i. a flexible hose disposed between an inner gripping member and an outer gripping member;
- and,
- ii. an tubular axial strengthening sheath having a diameter and configured to elongate and to reduce its diameter when subjected to axial tension.
