Method to allow a coating to be applied to a pipe elbow or curve (c) and, method for adjusting a flexible and elongated mandril to an elbow or curve (c) of pipe method that allows a coating (14) to be applied to an elbow or curve (c) of a pipe, includes By connecting the connecting steps of a connecting member (12) to one end of an elongated and flexible mandrill, passing the connecting member (12) through the elbow or curve (c),In order to pass the mandril through it and place the opposite ends of the adjacent mandril at the opposite ends of the elbow or curve (c),And attach the edges of the mandril to the respective ends of the elbow or curve (c);The mandril can be adapted to the elbow or curve (c),Or by positioning the elbow or curve (c) at a given orientation, to obtain a profile (s) or the elbow or curve (c) during that orientation, removing the elbow or curve (c) and then positioning the mandril at the given orientation, and adjusting the mandril relative to the c o -profile Speed or curve (c) to adapt it to it.
