METHOD AND DEVICE FOR CLEANING AND APPLYING PROTECTIVE PAINT COATING TO INNER SURFACES OF PIPELINES AT THEIR WELDED JOINTS Russian patent published in 2001 - IPC

Abstract RU 2177103 C2

FIELD: construction engineering; oil and gas industry; water supply; pipeline assembling and operating. SUBSTANCE: pipeline inner surfaces are cleaned and coated with protective paint within single pass by means of single system of blocks; provision is made for removing metal and paint dust after cleaning and extrusion of paint binding compound by means of dosing bellows and for drawing out the blocks to cleaning point by means of link gear. Proposed method and device provide for recovering coat damaged during welding operation to factory condition. EFFECT: reduced cost, hydraulic resistance of pipeline; enhanced service life. 2 cl, 1 dwg _
