The stress-strain state of the protective coating of the threaded pipe under the thermal force action of a high-temperature gas influence products

The article presents a study of the stress-strain state of the heat-protective coating of the channel surface of a threaded pipe during exposure to a high-temperature flow of combustion products under high pressure conditions.Gorenje et al. As a result of the study, the conditions of thermal force loading of the heat-protective coating on various parts of the surface of the threaded pipe were determined, and the destruction zones leading to the destruction of the protective surface layer were identified. The results obtained can be used as the basis for a rheological model of the destruction of a heat-protective coating when predicting the service life of a threaded pipe.
