    摘要： In order to reduce or remove the potential risk of heat damage in the absence of cooling jackets when joining lined pipe sections, each lined pipe section is provided with an insulatory sleeve which is disposed between the host pipe and the respective liner. The sleeves provide discrete thermal protection to the ends of the liners and, where applicable, electrofusion welds between an electrofusion fitting and the liners. The sleeves are first located in the ends of the host pipes which are then lined by drawing the liners through the host pipes via a reduction die to reduce their external diameter. The liners are then reverted towards their original dimensions resulting in a tight fitting against the internal surface of the host pipes and of the insulatory sleeves thereby compressing the insulation material.

    摘要： An electrofusion fitting (101) for joining liners (105a, 105b) of sections of lined pipe (103a, 103b), each liner (105a, 105b) being within a metal host pipe of a respective section of lined pipe (103a, 103b). The electrofusion fitting (101) comprises at least one heating element (107a, 107b) disposed on or in an outer surface of the electrofusion fitting (101). The, or each, heating element (107a, 107b) is electrically isolated from an inner surface of the fitting (101) and is configured to heat an associated portion of the electrofusion fitting (101) in response to electromagnetic induction.

    摘要： Methods and apparatus enable the integrity of a liner pipe to be quickly and effectively tested in the field, while permitting rapid removal and replacement of the liner pipe if it is compromised. The liner pipe is leak tested prior to reversion, after being pulled through a host pipe to be lined via a swaging die and while the liner pipe is still under tension. If the liner pipe exhibits a leak, it can be removed from the liner pipe immediately and, importantly, before it has expanded to contact the host pipe. Leak testing apparatus includes a packer, which seals the opposite end of the liner pipe from the end which is pulled, creating a contained fluid volume upon which the leak test is performed. The leak test may be a pressure test or a vacuum test or any other suitable test.
