摘要
FIELD: manufacture of oil and chemical equipment, vessels and apparatus.;SUBSTANCE: proposed method is performed outside plants after installation or repair. Proposed method includes heating the articles from the inside by flow of combustion products from heat generator through them at simultaneous excitation of elastic vibrations of audio range; heat generator may be used as source for excitation of such vibrations. Frequency of elastic vibrations depends on arising of vibrations of article at natural frequency; moment of attaining the resonance is defined by jump-type rise of amplitude of natural vibrations of vessel.;EFFECT: enhanced efficiency; simplified construction; reduced power requirements; improved quality.;2 cl, 2 dwg, 1 ex
