Abstract: An applicator machine and a process for heating and coating a section of pipeline. The applicator machine includes a frame configured to rotate about a section of pipeline to be heated and coated, rotating means operable to rotate the frame, and coating material applicators induction coils and radiant heaters mounted on the frame and rotatable therewith. The induction coil is configured to heat a section of pipeline adjacent to the induction coil to a coating material application temperature. The radiant heaters are configured to heat factory-applied coatings. Each coating material applicator sprays coating material through an aperture in a respective induction coil. The applicator includes an enclosure configured to surround a section of pipeline and provision for evacuating and collecting waste coating material. The coating material applicator may be configured to spray powder coating material, such as fusion bonded epoxy powder material and/or chemically modified polypropylene powder material.

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.
