abstract = "The main purpose of this study is to develop an appropriate welding procedure for the installation of full encirclement repair sleeves on in-service, internally coated water lines. The new proposed welding procedure can be effectively used to sleeve repair internally coated Fusion Bonded Epoxy (FBE) water line with no harm on the internal coating. Any possible damage of FBE can lead to frequent leaks. Prevention of coating damage will increase the reliability of the supply/injection water system. The cost saving will be observed in increasing the remaining life of the sleeved girth welds and defective trunk lines. In particular, full encirclement sleeve repair is well known repair method and its effect on internal coating has never been evaluated. To come up with the optimum combined welding parameters, an experiment has been conducted. Multiple weld passes were applied circumferentially and longitudinally to weld sleeve on in-service API 5L X60 pipelines of 12'' diameter X 0.375'' thickness. This experiment is carried out on coated test spools with internal pressure of 185 psig (12.75 bar) and raw water temperature of 180°F (82°C). From the actual observation of all cases performed, a specific and safe sleeve repair procedure is addressed in this paper.",
