A method is provided of applying an article such as a tape (2) to an elongate substrate such as a metal pipe (1). The article comprises a heat activatable adhesive (4) and is wrapped around the pipe. The tape and pipe are heated by applying a high frequency alternating magnetic field thereto, such that the ratio of the thickness of the pipe wall to the skin depth is at least 25:1. <IMAGE> |
