摘要： Methods and apparatus for making lined pipelines in which pipes are joined together by attaching fittings at their ends and joining the fittings together. Within the joint there is a fit-up sleeve which forces liners against respective fittings and provides corresponding seals. Other seals can be provided by inserting sealing rings which force different portions of the liners against different portions of the fittings. The fit-up sleeve and sealing rings may force the liners against castellations which prevent movement of the liners. The fit-up sleeve may cooperate with insertion rims on the fittings to provide very accurate spacing, or touching edges which can be desirable if automatic welding is employed. The seals provided by the fit-up sleeve also eliminate backdraughts and assist welding operations. Furthermore, the fit-up sleeve permits pigging through the pipe joint and therefore along the length of the resulting lined pipeline. It is foreseen that the need for CRA components and CRA welding can be largely if not wholly dispensed with.

摘要： A device internally insulating a welded pipeline joint between pipes having an internal protective coating, in a first variant, includes a power actuator having a cylindrical elastic working member for radial expansion when excess pressure occurs inside its cavity. A cylindrical casing of elastic anti-adhesive material arranged coaxially on the member exterior can have channels for exhausting air and supplying a compound. In a second variant, the device sleevelessly insulates an annular space. A casing made of an anti-adhesive material is centrally reinforced by an elastic cord. Using a cylindrical elastic anti-adhesive casing coaxially arranged on the exterior of a power actuator elastic working member forms an annular space in the weld zone either using a protective sleeve, or by a reinforced casing portion. A vacuum in the space is filled by a compound. The elastic anti-adhesive material allows easy removal of the casing from the hardened compound surface.

摘要： In the proposed method, a protective sleeve is plastically deformed to dimensions enabling the shape of the sleeve to correspond to the shape of the interior surface of the pipes to be joined in the joint region. The deformed sleeve is installed inside the pipes to be joined such that an annular cavity is formed between the sleeve and the region of the welded joint together with the adjacent portions of the pipes protected by a coating. The ends of the pipes are joined by welding and the annular cavity is hermetically sealed at the ends of the sleeve. Once sealed, the cavity is evacuated and, via working apertures in one or both of the pipes to be joined, the annular cavity is filled with a liquid sealing material, which is then polymerized. During installation of the protective sleeve, a steel cushioning ring can additionally be positioned between the sleeve and the welded joint, wherein the outside surface of the cushioning ring contacts with the surface of the welded joint and the inside surface of the cushioning ring is provided with projections which contact with the outside surface of the sleeve. As the joint is welded, the ends of the pipes are welded to the steel cushioning ring. The technical result is more reliable and durable corrosion protection of a welded pipe joint.

摘要： There are disclosed methods of and apparatus for interconnecting lined metal pipes (110, 120), applying in particular to the offshore oil and gas industry. Corrosion is a common problem in the industry. Lining pipes overcomes the problem, but welding sections of pipe together can be a complicated and time-consuming task, requiring dedicated and sophisticated tooling. More desirable is the ability to use conventional pipe-laying equipment (20, 40, 50, 60, 70, 80, 90) with little additional tooling. As such, there are disclosed methods and apparatus compatible with known offshore connection methods, particularly where the spacing of joints on the pipe is less than 100 m. The chosen technique will not significantly impact the laying rate of the lined pipe, compared with unlined pipe. The method includes connecting lined pipes (110, 120) using a corrosion-resistant bridging member (102) internally overlapping both linings, leaving a void space (146) behind the weld region (109) while at least the initial stages of welding (180) are performed, and expanding (170) the bridging member to provide a seal against the liners, in a controlled sequence. There is also disclosed a bridging member (102), tooling (170) and pipelay apparatus suitable for use with this method.

摘要： The invention provides a joint 80 for two steel pipes 50, 52 each containing a liner 54, 56 of polyethylene. The invention also provides an electrofusion fitting for joining the liners 54, 56; a method of making the fitting and a method of making the joint 80. The joint 80 consists of an electrofusion fitting having two frusto-conical outer end surfaces which match similar surfaces on the insides of the end portions of the liners 54, 56. Fusion welded joints are formed at the interfaces between the frusto-conical surfaces. A body of insulating material 66 is received in a central recess in the fitting and protects the fitting from the high temperature of the seam 70 between the steel pipes 50, 52. The frusto-conical surfaces make an angle of 10.degree. or less with the longitudinal axis of the fitting. A support body 14 of metal or of synthetic plastics material contained by the electrofusion fitting ensures that the fitting is adequately supported during electrofusion.
