Abstract: A pipeline field joint abrasive blast cleaning machine is disclosed in which direct contact between the pipe to be cleaned and drive rollers of the machine ensure a constant, known distance exists between the blast nozzles of the machine and the pipe surface. This ensures uniform application of abrasive matter to ensure uniform cleaning of the pipe surface.

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.

Abstract: An apparatus for heating a pipe, having at least one heating unit, at least one temperature sensor and a controller, wherein the controller is arranged to control the at least one heating unit in dependence on the temperature measured by the temperature sensor.

Abstract: A pipeline field joint coating applicator machine. The machine having a first frame arranged to be mounted on a pipeline, the frame carrying an induction heating coil which encircles the field joint for heating. A second frame mounted on the pipeline and rotatable thereabout, which second frame carries a pipeline field joint coating applicator. A dust extraction hood mounted on the second frame having lateral sides with respective holes therein through which the pipeline may pass. The dust extraction hood is coupled to a vacuum source and a filter such that air may be drawn into the hood via one or both of the holes so that coating material-contaminated air is filtered.

Abstract: Apparatus for coating pipes includes means for applying a sheet material 32,33,34, to a pipe 2 and means for heating 23,31 the sheet material and/or pipe. The means for heating may be operative to heat the sheet material during its application to the pipe. The means for heating may comprise a means for directing hot air towards the pipe and/or sheet material. The sheet material may be disposed on reels housed in canisters 22 that are releasably mounted on the apparatus.

Abstract: Apparatus for spraying a coating onto the outside of a pipe includes a body for mounting on a pipe to be coated. A spray gun is mounted on the body such that it can move relative to the body to spray coating completely around the periphery of the pipe. The apparatus may include only a single spray gun which is able to travel in a 360 degree range of motion around the periphery of the pipe. The apparatus is particularty suited to coating girth welds of a pipeline.

Abstract: A system for first heating a section of pipe and then wrapping a sheet of heat-shrinkable material around the pipe to cover the section, the heat-shrinkable material having an outer polyethylene side and an inner mastic side which goes against the pipe, the mastic side forming a mechanical bond to the pipe when heated and having a lower melt temperature than the shrink temperature of the material, comprising arranging a plurality of induction coil assemblies in spaced relation around the pipe section, the induction coil assemblies having relatively arcuate induction coils therein, mounting the coils on a rotation fixture to form an arcuate surface adjacent to and parallel with the surface of the pipe, locating a heater assembly on the rotatable fixture between a pair of induction coil assemblies, rotating the rotatable fixture around the pipe section to heat the pipe section to the melt temperature of the mastic, wrapping a sheet of heat-shrinkable material around the pipe to form a sleeve with overlapping en
