LinerBridge® Connection System The fusion of steel pipe and polymer liners Introduction
7 1 A vision of connector technology for the future By combining its experience in fabricating onshore and subsea pipelines and riser systems with polymer materials technology and fusion welding, Swagelining Limited (SWL) has developed a genuinely novel connector system for joining polymer lined carbon steel stalks together. The LinerBridge® Connection System is a step change in weldable connector technology for polymer lined pipelines and risers. The vision driving the connection system development is to make it easier to build and install polymer lined pipelines. The LinerBridge® Connection System comprises a number of components that can be flexibly interchanged to suite
The LinerBridge® Connection System is designed to:• Reduce the cost of lined pipelines • Reduce risk in fabrication and installation of lined pipelines • Eliminate (or reduce) corrosion resistant alloy materials from system hardware • Enable lined pipelines and risers to be cut to length offshore and terminated efficiently • Facilitate the repair and / or replacement of damaged sections of lined pipelines • Make it possible to tie in additional facilities to existing lined pipelines
New thinking delivers improvements When compared to the existing weldable connectors made using corrosion resistant alloy materials, the LinerBridge® Connection System is a revolution in connector technology. There are three significant differentiators underpinning the step change from existing connector architecture:-
1. I t’s made from polymer, not steel or alloy The LinerBridge® Connector is made from the same polymer material as the liner. It is joined to the liner internally by fusion welding. The result is a continuous polymer liner along the pipeline length. Through the careful use

strategy.
carbon steel girth welds can be made over the LinerBridge® Connector using standard pipeline welding processes. No purging or specialist CRA weld operations required.
