Abstract

The end of a thermoplastics tube is heated or cooled to form a socket by passing a heating or cooling fluid over the surface of the tube. A fluid of increased density is used. Pref. the density is increased by adding powder or particles of a solid possessing good thermal conductivity, partic. graphite. Pref. air at a pressure of is not 1 bar gauge, is used. The increased heating and cooling rate results in a shorter total time for forming the socket.
