ASSESSMENT OF THE BEHAVIOR OF FIRE-PROOF COATINGS IN THE TEMPERATURE FIELD FROM –162 TO +1300o C FORMED DURING ACCIDENTS INVOLVING LIQUEFIED NATURAL GAS

At present, in the Russian Federation, there is no unifi ed standard method of testing protective coatings for cryo- and fi re-resistance that would refl ect the specifi city of accidents involving liquefi ed 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 fi re 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^o C in conditions of a cryochamber and a furnace with respect to the criterion of the time of reaching brittleness and yield points.
