    摘要: For continuous high temperature operation over a service life in excess of twenty years, a flexible pipe joint (18) includes various features that tend to reduce the temperature of the load-bearing flex element (25) or reduce strain in the warmer elastomeric layers of the flex element (25). These features include a heat shield (33) of low heat conductivity material integrated into the inner profile of the pipe extension (23) and interposed between the central bore of the pipe joint (18) and the flex element (25), low heat conductivity metal alloy components between the hot production fluid and the flex element (25), high temperature resistant elastomer at least in the warmest inner elastomer layer of the flex element (25), and a flex element (25) constructed to shift strain from the warmer inner elastomer layers to the colder outer elastomer layers by providing greater shear area, different layer thickness, and /or higher elastic modulus elastomer for the warmer inner elastomer layers.

    摘要: A double-ended flexible pipe joint (26) has first and second extension pipes (51,52) extending from opposite ends of an outer housing (50), and first and second primary annular elastomeric flex elements (71,74) mounting the first and second extension pipes (51,52) to the outer housing (50). An inner housing (80) is disposed in the outer housing (50), and first and second secondary annular elastomeric flex elements (81,82) disposed in the inner housing (80) mount the first and second extension pipes (51,52) to the inner housing (80). Tension upon the first and second extension pipes (51,52) places each of the first and second primary flex elements (71,74) and each of the first and second secondary flex elements (81,82) in compression. The first and second secondary flex elements (81,82) contain fluid pressure within the first and second extension pipes (51,52) so that the first and second primary flex elements (71,74) are not subjected to the fluid pressure within the extension pipes (51,52).
