Abstract (en)

[origin: WO2004020893A1] Apparatus (10) for lining an internal surface of a pipeline (15) or other conduit. The apparatus (10) comprises an installation head (21) which is progressively moved along the pipeline (15) for installing a flexible liner (11) onto the interior surface (13) of the pipeline (15). The flexible liner (11) comprises a tube structure (17) undergoing eversion within the pipeline (15). The tube structure (17) comprises a resin absorbent material. The installation head (21) has a contact surface (23) against which the tube structure (17) acts during eversion thereof, the contact surface (23) having means for delivery of a curable resin to the everting portion of the tube. The installation head (21) advances along the pipeline (15) under the influence of a driving force comprising (at least in part) pressure applied to the installation head (21) through the everting tube structure (17).
