Pipeline surface preparation for inspection with debris collection |
摘要 |
A machine for surface preparation of a pipeline includes a vacuum shroud that encircles the pipeline. Three manifolds, each housing a plurality of ultra high pressure water nozzles, are mounted in the vacuum shroud at circumferentially spaced intervals. A carrier assembly advances the vacuum shroud along the pipeline at a rate that avoids contact between the water jets and uncoated pipe. The shroud also oscillates about a longitudinal axis of the pipeline so that a short extent of the pipeline is subjected to the force of the water for each oscillation. The vacuum in the shroud carries away all debris created by the coat-stripping process to a closed loop filtration and recycling system. The nozzles are mounted a constant stand-off distance from the pipeline to avoid creation of hot spots during the stripping process. All motions are electronically monitored and detection of any movement failure results in system shutdown.
