The successful application of plastic liners for flowline corrosion control requires connector and termination technologies to link individually lined pipe sections. This review describes typical applications, installation procedures, performance and cost of the different connectors which have thus far been employed, both onshore and offshore, on lined flowlines. Possible future developments will be described. Onshore, the most economical and widely proven connection is the raised face flange type, constructed either using pre-manufactured PE flanges fusion welded to the end of the installed liner, or using the liner itself formed / flared around the face of the steel flange. Offshore, developments have centred on the need for lines to be reeled during installation. This has led to the use of welded connectors, in which liners are mechanically terminated either side of the tie-in welds, with alloy steel pup pieces providing corrosion resistance in between. Keywords: plastic liners, connections.
