APPARATUS FOR AND METHOD OF LINING CONDUITS

摘要

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 ).
