FIELD: construction.
SUBSTANCE: internal surface of pipeline is cleaned by cleaning mechanism displacing inside the pipe. The cleaning mechanism is comprised of a shaft with naves and elastic and flexible blades being mounted on the naves in staggered order. The blades generate liquid jets that damage deposits on the pipeline walls. The hydraulic resistances are oscillated in liquid flow and hit pipeline wall. There are chambers installed on the ends of pipeline, where drums and sleeves are inserted. The end of sleeve is bent and forms cavity, which is connected to the liquid agent supply system. Flexible casing in the form two sleeves is inserted into the pipe from the opposite sides. The ends of both sleeves are bent and fixed around pipeline perimeter. The casing is inflated by supplying liquid agent. As a result a cavity is form between sleeves and filled up with solution. Solid coating is applied by sleeves over-rolling along the pipeline with the solution being delivered between them. Diametre of one sleeve is equal to inner pipeline diametre, while the other sleeve diametre is similar to inner pipeline diametre plus applied coating.
EFFECT: wide range of facilities.
