Abstract: An apparatus for coating pipes includes a spraying device rotatable around a pipe. The coating apparatus includes a guiding ring mounted around the pipe and a carriage to be mounted on the guiding ring, the carriage being motor driven, the motor being enclosed into the carriage and the carriage including an adjustable device to be detachably mounted on the guiding ring.

Abstract: A pipe joint coating for welded ends of pipes forming a pipeline. A last and third layer of a 3LPP coating system covering at least a circumferential weld area of the pipe joint is a heated sheet applied around the pipe with a machine including a mounting frame and a transport carriage rotatably movable on the mounting frame to move circumferentially about the pipe joint, and a roller applying an adjusted pressure to the sheet against the pipe and adapting to eccentricity or ovality of the pipe. The sheet is pressed below the pipe away from its overlapping ends, a first part of the sheet is then applied when the roller is rolled in a first direction, and a second part of the sheet is applied by the roller rolled back in the reverse direction around the pipe. The sheet is dimensioned to obtain an overlapped area between its extremities.

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: 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
