A distinctive feature of the pyrolysis furnaces of hydrocarbon raw materials from other types of furnaces operated at the facilities of oil and gas chemical enterprises is the strict operating conditions necessary for the implementation of this process. At the same time, the temperature of the radiant coil in operating conditions can reach 1050 ° C. In this regard, the probability of failure of coils of pyrolysis furnaces due to defects and damages during operation is extremely high. In addition, variations in coil shape and dimensions that occur during manufacturing or operation can negatively affect the overall stress-strain state of the coil during operational loads. In this work, the influence of permissible deviations in the shape and dimensions of pipes used in the welding of the coil on its stress-strain state in working conditions is investigated.
