PRESSURE ISOLATION SYSTEM FOR FLEXIBLE PIPE JOINTS

A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupl...

description A flexible pipe joint has two annular elastomeric flex elements stacked in a co-axial fashion at an inner radius from a common center of rotation, and at least one elastomeric flex element disposed at an outer radius from the common center of rotation. The flex elements at the inner radius are coupled mechanically in series between the extension pipe and the housing of the flexible pipe joint, and the flex element at the outer radius is coupled mechanically in parallel with the series combination of the inner flex elements. The inner flex elements isolate the flex element at the outer radius from transport fluid, and the flex element at the outer radius reduces the axial compression of the inner flex elements. Thus, the inner flex elements may have a reduced radius and a different composition to handle a higher loading of heat and pressure.
