Abstract: A method for providing protection against corrosion of a pipe joint (1) formed by the mating of complementary ends (4, 5) of two pipes comprising the steps of:(a) applying controlled heating to a pipe body which is to be joined to an adjacent pipe,(b) applying to the ends (4, 5) of each pipe a protective layer or coating of material 2 to the pipe body by a time/temperature function process,(c) allowing the pipe to cool,(d) bevelling the terminations of the protective layer or coating (2),(e) mating complimentary ends (4, 5) of the pipes together to form a sealed and corrosion resistant joint (1).
