    Abstract: An expandable tubular connection includes a pin member and a box member. The pin member includes a pin thread formed on a small step and a large step and a first seal surface formed between the small step and the large step. The box member includes a box thread formed on a small step and a large step and a second seal surface formed between the small step and the large step. The pin thread and the box thread are wedge threads. Upon a selected make-up of the pin member with the box member a selected gap exists between the first seal surface and the second seal surface. The gap is selected such that, when plastically radially expanded by a selected amount, a seal is formed between at least a portion of the first seal surface and the second seal surface.

    Abstract: A method for making a composite lined tube is disclosed, wherein the tube has end couplings on it. The method includes pressing a resin impregnated fiber preform progressively along an inner wall of the tube. In one embodiment, the method includes inserting an inflatable bladder into the tube. The bladder is adapted to inflate along a length thereof on application of increasing pressure to the interior of the bladder. The bladder has disposed on its exterior surface the fiber preform impregnated with resin which is adapted to fit within the tube. One end of the preform is secured to one end of the tube. The bladder is then inflated along its length by applying increasing pressure to the bladder. The preform is clamped to a shoulder of one of the couplings at another end of the tube, and the end of the preform is trimmed to conform to the shoulder. Pressure is maintained in the bladder while curing the resin. In one particular embodiment, the bladder is inflated from its center outwardly to its ends. In another particular embodiment, the bladder is inflated at one end progressively towards the other end. In a particular embodiment, the resin curing is assisted by inductively heating the tube.
