2081892 9117362 PCTABS00008 A method of joining two sections of metallic pipe (1), each of which has a thermoplastic polymer lining (3), to form corrosion resistant joints is disclosed. The method comprises inserting a sleeve (10) into each section of two pipes (1) that are to be joined so as to form a fluid tight seal between the liner (3) and the sleeve (10). The end of each section of pipe is then bevelled, and the two sections are welded together so as to form a corrosion resistant weld between each section of pipe and each sleeve and between each of the sleeves. The method is particularly useful in the lining of metallic pipe in the field e.g. in pipelines, without having to form flange joints.
