Abstract:
Pipe joint coating for welded ends of pipes forming a pipeline, where the last and third layer of a 3LPP coating system covering at least a circumferential weld area of the pipe joint is a heated sheet (20) applied around the pipe with a machine having a mounting frame and a transport carriage rotatably movable on the mounting frame to move circumferentially about the pipe joint, and a roller (6) applying an adjusted pressure to the sheet against the pipe, the roller adapting to any eccentricity or ovality of the pipe. The sheet is pressed below the pipe at a location of the sheet away from its overlapping ends (30, 31 ), 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 both extremities of the same sheet.
