摘要

At present, in the Russian Federation, there is no unified standard method of testing protective coatings for cryo- and fire-resistance that would reflect the specificity of accidents involving liquefied natural gas (LNG). In the existing methods of testing for cryoresistance, use is made of harder conditions than in LNG action on an object with an applied protective coating, and fire tests are carried out at a lower temperature than the temperature of combustion of LNG vapors under real conditions. A thermophysical calculation has been performed for a number of protective coatings applied on a steel plate under the action of the temperatures of –176 and 1100°C in conditions of a cryochamber and a furnace with respect to the criterion of the time of reaching brittleness and yield points.
