Abstract

Dielectric heating jig for softening the ends of thermoplastic pipe where the pipe end is pushed over a (heated) mandrel and enclosed by (spring loaded) segments of a heated cylindrical sleeve, which bear radially against the outside of the pipe, Pref. the sleeves remain stationary and the mandrel holding the pipe bore is rotated, or vice versa. Pref. the mandrel has a tapered nose and shallow asymmetric flights to support and restrain the pipe bore with minimal wall contact. Offers clean symmetrical heating of a controlled depth of the pipe end prior to forming a socket joint for coupling successive lengths of pipe.
