Abstract: A device for cleaning the internal surface of a pipe has a main pipe axis. The device further includes one or more generally tubular conduits, including a conduit wall, at least one of the or each tubular conduit including an inlet to receive pressurised gas into the tubular conduit. One or more nozzles is deployed around the outside of the or each tubular conduit, with the or each nozzle being in fluid connection with the tubular conduit. At least one nozzle is directed at least partially to direct fluid in a direction non-perpendicular to the main tubular conduit axis, with one or more spacer elements to hold the or each tubular conduit in spaced relationship to a pipe.

Abstract: A method of cleaning the inside of a pipework includes selecting a section of the pipework to be cleaned and determining a hold point of the pipework. A cleaning apparatus is inserted into an entry point of the pipework section, the apparatus being coupled to a fluid supply and equipped to blow the fluid along the pipework section from the first or last hold point to the entry point. The apparatus further includes an image recorder to obtain a visual record of the inside of the pipework. Insertion of the apparatus into the pipework continues until the apparatus reaches the hold point. A collector is secured over the entry point to collect debris blown from the pipework, and fluid supply is activated. The apparatus is moved from the hold to the entry point, so blowing debris towards and into the collector. On completion, the fluid supply is deactivated and the collector containing the collected debris removed from the entry point.
