FIELD: process engineering.
SUBSTANCE: invention relates to processing inner surface of tubes, for example, coolant tubes of steam condensers and heat exchangers. Proposed device comprises tube feed and transfer device, unit to apply processing material fed by aforesaid device, and control device to control tube processing material feed and application on tube inner surface. Said application unit has guide hose incorporating application hose fitted therein to be fed into tube to be processed that terminates in injector. Said application hose may be wound in one layer on driven drum and locked thereon be belts and to reciprocate on guide rolls moving in carriage. Said guide rolls are provided with drive timed with drum drive while moving carriage may travel parallel with drum axis depending upon application hose position.
EFFECT: higher efficiency.
