Connectors are required to join lengths of polymer lined pipeline together to form the overall pipeline length and to terminate the pipeline. In onshore service this function has been achieved using bolted flanges. In subsea application, welded CRA connectors have been used historically. With flanges not suitable for subsea application, CRA connectors have limited the use of polymer lining due to their expense and complex welding procedures. This has resulted in the true cost benefit of a polymer liner solution not being realised.
To remove the need for CRA welding from the pipeline infrastructure, Swagelining have developed the LinerBridge® connector. Manufactured from the same material as that of the liner, our innovative connector contains no CRA materials.
This reduces connector procurement costs and schedule and allows for standard carbon steel welding procedures to be utilised for pipeline tie-ins.
LinerBridge® uses robust and proven electrofusion welding technology adapted from the onshore utilities gas industry to provide a continuous polymer corrosion barrier from pipeline end to end.
LinerBridge® offers a step-change in the application of polymer lines, and is suitable for onshore and offshore use. The connector can be welded in 2G (J-Lay), 5G (S-Lay and onshore tie-ins) and 6G (reel-lay) positions, allowing installation via J-lay, reel-lay and S-lay assets.
LinerBridge® has been qualified by DNV GL to Technology Readiness Level 5, meaning it has been verified as suitable for its intended use. The qualification process has demonstrated the ability of the connector to form robust, ductile fusion welds with provision of a fully integrated PE100 lining solution.
