As. Bakunov et al., NONDESTRUCTIVE EVALUATION OF CORROSION DAMAGE TO GAS AND OIL PIPELINES UNDER A PROTECTIVE COATING AND MEASUREMENT OF COATING THICKNESS, Russian journal of nondestructive testing, 32(2), 1996, pp. 94-96
A description is presented of an instrument developed for measuring th
e thickness of protective coatings on gas and oil pipelines. A method
is described for detecting corrosion damage to the pipe under the coat
ing and determining the degree of danger posed by the damage.
