Abstract
An alloy of cast pipes produced in the Russian Federation and a welding method for restoring coil sections made of imported pipes damaged by gas corrosion in pyrolysis furnaces are proposed. Substantiation of the alloy choice is carried out according to the research results of composition and structure of the metal of the original pipes and according to the criteria of structural strength using a proven diagram of controlled damageability. Recommendations for optimizing the composition, microalloying, and structure of the proposed alloy of thick-walled cast pipes for the elimination of the deficiencies identified by the research are presented. The alloy advantages by mechanical properties in the temperature range up to 800…890°C are shown on samples of an experimental cast pipe.
