A method of protecting the end face of a metal composite pipe. The method comprises the steps of providing a metal composite pipe of the kind comprising inner and outer plastics layers and a central metal layer. A pipe insert of the kind having first and second ends and defining a flow path between the first and second ends for allowing fluid to flow along a longitudinal axis of the insert. The first end of the insert defines a body configured for insertion into the free end of the pipe and the second end of the insert defines a head configured to project from the free end of the pipe and limit the degree of insertion of the insert into the pipe. The second end of the insert includes an abutment surface intended for abutment with an end face of the pipe. The diameter of the abutment surface is sufficient cover at least part of the outer plastics layer of the pipe. The method further comprises the steps of locating the first end of the insert inside a free end of the pipe and arranging said abutment surface of the head in abutment with an end face at the free end of the pipe and immovably fixing the abutment surface of the head in contact with the end face of the pipe in order to seal the central metal layer at the end face of the pipe against fluid contact. |
