Abstract

Enhanced process for the renewal of inaccessible pipes through the internal lining of same with a solid multilayered synthetic repair hose, based on the following four steps: adjusting the size and the reinforced layer of the repair hose to the inner surface of the pipe to be required; impregnating under negative pressure the hose with a thermosetting resin; drawing in and applying the repair hose against the inner wall of the pipe by gas pressure and finally controlled hardening of the resin in the reinforced layer of the inserted repair hose - if necessary, by means of an ultra violet radiation robot device. The repair hose used in this process is produced by welding or gluing together several synthetic layers. It comprises on its outer surface a film impervious to liquid, gas and ultraviolet radiation and on its inner surface a reinforced layer made of either a felt-like woven or non-woven or knitted material, or a loosely woven or knitted material or else a woven or knitted material with a specially-structured weft.
