  • Method of joining components made of cross-linked polymers
    Patent number: 3972548
    Abstract: The invention relates to a method of joining components made of cross-linked polymers, at least one of the components being a tube, which method comprises deforming at least one of the components so as to deviate from the cross-linking shape, inserting an end of the tube into the other component, and heating the joint location to the temperature where the deformed components tend to return to the cross-linking shape, the heating being maintained for a time sufficient to produce fusing together over the joint location.
