There is described an improved method for lining a pipe utilizing a pipe-received forwardly traveling machine comprising a forward seal and a following cylindrical platen defining a chamber therebetween, the method including the steps of forming the platen of a radiant energy transparent material and with an internal source of radiant energy, introducing a flowable liner-forming material into the chamber, distributing the flowable material in an annular space about and along the cylindrical platen between the platen and the pipe to define a constant thickness liner, and supporting the material in the space by the platen as the machine travels forward to form the liner in intimate contact with the pipe, and subjecting the liner material to radiant energy through the platen, as the material is supported by the platen, for curing or accelerating the curing of the liner material.
