Abstract: A flame coating machine for coating field joints of a pipeline has a flame spray system having two flame spray units configured for heating and/or coating with a thermoplastic polymer an annular junction portion and two annular end portions of an existing coating delimiting the annular junction portion; a control system having two temperature sensors configured for acquiring temperature values along the surface collectively defined by the annular junction portion and the annular end portions, and a control unit configured for actuating the flame spray unit in a polymer flame spraying mode or in a flame heating mode as a function of the detected temperature values and at least one threshold value.
