Abstract
The invention concerns a method of joining two reinforced thermoplastic material tubes having the same diameter. Ends of the two tubes are first butt welded along a peripheral weld. After forming the weld, a reinforced thermoplastic material outer jacket is fitted over most of the length of the peripheral weld, extending on either side of the weld over end sections of the two tubes. The outer jacket is heated and pressed radially until the outer jacket and the end sections of the two tubes interpenetrate.
