Annotation:The article deals with the influence of caused-by-leak fire on the stressed and strained state of the process lines. Numerical and practical experiments were conducted, and obtained results were used to plot temperatures of heating and of further fire suppression against the state of pipeline segments.

 

Key words: caused-by-leak fire, stressed and strained state, temperature field, pipeline final element model, equivalent stresses.
