Abstract
Apparatus for removing material lining the inside surface of a cylindrical structure, the apparatus comprising: a support for supporting the structure in a horizontal orientation; an elongate horizontal boom for being inserted into the structure; a nozzle assembly connected to the boom member, the nozzle assembly comprising one or more nozzles wherein each nozzle is suitably spaced from the lining to deliver a jet of fluid under pressure to the lining; a conduit in fluid communication with the nozzle assembly suitable for delivering a flow of fluid to each nozzle under sufficient pressure to cut the lining material adjacent the nozzle; and a rotation mechanism cooperating with the support to passively enable the structure to being rotated while supported by the support or to actively impart rotation to the structure while supported by the support, wherein the rotation of the structure is about a central longitudinal axis of the structure.
