ABSTRACT:
A method of making a flanged pipe length includes flaring a metal pipe by rotating a grooved tool about the inside of the pipe and introducing a plastic tubular sleeve into the pipe. The tubular sleeve is subsequently heated and forced against the flanged portion of the metal pipe whereby the plastic material assumes a shape complementing the projections formed by the grooved tool.
