Abstract

In a method of laying a separate channel inside a fluid carrying duct (20) a liner (1) is introduced into the duct (20). The liner (1) comprises an elongated, flexible sleeve (2) and at least one flexible tube (5, 6) joined to and extending along said sleeve (2) being around its circumference at least partly surrounded by a hardenable material (7). The sleeve (2) is then pressed against the inner periphery (22) of the duct (20) by means of a pressure acting inside the sleeve (2), while the tube (5, 6) at the same time is subjected to an internal pressure, that is large enough to dilate the tube (5, 6) and said hardenable material (7). The sleeve (2) and said hardenable material (7) are subjected to a hardening treatment for forming an inner pipe (27) and said channel (25, 26), respectively, inside the duct (20). The pressures in the sleeve (2) and in the tube (5, 6) are then relieved.
