Robotic external pipeline crawler system employs the use of logic control to provide a system capable of constantly and accurately maintaining a position at the vertex of the pipe. This apex positioning can be maintained as it traverses the length of the pipe being inspected. This system is adaptable to both straight and curved pipe, multiple pipe diameters, and will substantially reduce set up time and vertical pipeline support crossing time. The crawler system also employs an advanced bracketry system which allows quick disconnecting and auxiliary powered movement allowing for decreased cycle time across pipe supports. The unique tire interface allows for additional surface area contact making extreme environmental conditions possible.

Crawler for inspecting pipes

A spray cleaning apparatus for tubular filter elements, comprises a spray chamber in which a filter element is mounted between opposed rotary turntable discs. The chamber is provided with liquid sprays for spraying both the inner and outer surfaces of the element as it is rotated by the turntable. The sprays are reciprocated vertically so as to traverse the height of the filter element. Particular features of the invention reside in the turntable construction; a control system for accurately reversing the up-and-down movement of the sprays dependent on the height of a filter being cleaned; and a particular form of spray nozzle structure useful for cleaning pleated filter elements.
