Method of attachment of the tube of thermoplastic resin in a thermoplastic support. The application for the manufacture of heat exchanger

摘要

The invention relates to a method for fastening a tube made of thermoplastic resin in a support made of thermoplastic resin by welding, involving fitting the end of the tube into the support pierced right through along a cross-section complementary with that of the tube, characterised in that the assembly consisting of the end of the tube fitted into the support is immersed at least partially in a liquid bath at a temperature at least equal to that of the melting point of each of the thermoplastic resins. The invention is particularly suitable for the production of heat exchangers. IMAGE
