Zusammenfassung:	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 coatingsystem (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 amethod. 本发明涉及一种用于外部涂覆具有内覆层(3)、尤其是内镀层的管(2)的方法，所述方法包括：在涂覆设备(1)中提供管(2)，通过加热装置(10)局部地加热管(2)的待涂覆的外表面区域，通过冷却装置(11)在被加热的外表面区域中局部地冷却内覆层(3)，从而在该处在管(2)和内覆层(3)之间的过渡区间(14)中不超过第一界限温度(T)，并且在待涂覆的外表面区域中不低于第二界限温度(T)，借助于涂覆装置(8)涂覆被加热的外表面区域。本发明也
