  • Patent number: 10486181
    Abstract: Apparatus for coating a pipe. The apparatus includes a first frame to be mounted on a pipe and a second frame rotatably mounted on the first frame. An induction heating coil comprised of electrical conductors is mounted on the apparatus. A coating applicator is mounted on the second frame and is arranged to apply coating onto a surface of the pipe on which the apparatus is mounted. The first frame, second frame and coating applicator are arranged such that when the apparatus is mounted on the pipe, the applicator is disposed to one side of the induction heating coil and able to apply coating to a surface of the pipe alongside the surface of the pipe underlying the induction heating coil. The first frame may be operable between an open state in which the frame may be placed over and removed from a pipe and a closed state in which the frame may capture a pipe thereby to mount the apparatus on the pipe.
