More Information
Summary:The present invention relates to a method for coating the exterior of a pipe (2) having an interior coating (3), more particularly an interior plating, comprising: providing the pipe (2) in a coating system (1), locally heating an exterior surface region of the pipe (2) to be coated using a heating device (10), locally cooling the interior coating (3) using a cooling device (11) in the region of the heated exterior surface area such that in a transition zone (14) between the pipe (2) and the interior coating (3), a first threshold temperature (TG1) is not exceeded and in the exterior surface region to be coated, a second threshold temperature (TG2) is not undershot, coating the heated exterior surface region by means of a coating device (8), and a coating system (1) for carrying out such a method.
