摘要
针对辽阳石化分公司烯烃厂F108裂解炉对流段炉管爆裂破坏进行了分析.结果表明,爆裂原因是由于炉管在高温下长期运行,管壁氧化腐蚀减薄并影响传热,同时管壁金相组织发生变化,使得炉管强度降低所致.
The burst part in convection section of a tube of F108 cracking furnace in alkene factory, Liaoyang Petrochmical Company, was anatyzed. It was found that the burst of the tube was mainly caused by the long time oxidation of tbe tube at high temperature, which resuhed in significant decrement of thickness of the tube. Another reason was tbat the microstructure of the tube changed and therewith, its strength decreased during service at high temperatures.
