FIELD: oil and gas industry.
SUBSTANCE: invention relates to a technology for studying strains and stresses in constructions of hazardous production facilities of gas and petrochemical industry. ESSENCE: a brittle strain-sensitive porous coating with freon is applied to the detail surface, coating curing and structure loading are carried out, and the freon gas release zone from the porous coating (bubbles are bursting) and the direction of plastic stress during deformation using acoustic emission sensors are determined. The brittle strain-sensitive coating is made of a mixture containing epoxy resin, a hardener probe, gas freon R-22 in the following ratio, wt %: 65-84 epoxy resin, a hardener 14-33 probe, gas freon R-22 2-10.
EFFECT: invention enables to determine the stresses and strains using brittle coatings at the very early stage, eliminating negative effect on the environment.
