Method and apparatus for coating a pipe (2) or a pipe section with a layer of at least one polymer. The method comprises providing a pipe (2) or a pipe section having an outer surface defining the periphery of the pipe or pipe section; applying on the outer surface of the pipe or pipe section a layer of at least one polymer material in melt stage using a nozzle (3), which is mounted on a carriage capable of travelling along the periphery of the pipe (2) or pipe section; and moving the carriage along at least a part of the periphery during the application of the polymer material to form a layer on the surface of the pipe (2) or pipe section. The present invention is particularly useful for coating field joints in pipelines. |
