Pipelines are an indispensable component of many distribution systems, including potable water, commercial and domestic fuel, and hydrogencarbon exploration and development. Plastic lined water injection pipelines for the upstream hydrocarbon industry have, until now, been installed by the reeling method, whereby stalks of welded steel pipe of between 300 m and 1000 m can be lined onshore. In this method, welded connections of the lined pipe are infrequent, and do not have a major cost impact. When reeling is impractical, because of large diameters, very deep water, or long distances, much shorter plastic-lined stalks, typically 50 m, must be welded together, in which case the cost per joint is much more significant. A method is described that maintains the corrosion barrier across a welded joint in any diameter of pipeline. Currently it is aimed at water injection pipelines, but patented features of the design make it suitable for hydrocarbon service also. The background to plastic lining of pipelines is briefly discussed, the joint itself described, and addressed how it fits within existing installation procedures.
