摘    要:石油化工厂的部分高温烟气管道长期在650~700℃左右运行,研究表明,碳钢部件工作温度高于350℃、合金钢部件工作温度超过420℃、不锈钢部件工作超过480℃时,进入蠕变温度。通过对某石化厂原有高温烟气出口管道运行工况分析,运用CAESARII应力分析软件优化管道布置,并通过计算管道蠕变条件下服役年限进行安全评定。

关 键 词:蠕变  应力  高温管道  CAESARII

Abstract:Some high temperature flue gas pipelines of petrochemical enterprises always run in 650 - 700 or so℃ for a long time. The researches show that the creep temperature of carbon steel pipeline is about 350 ℃, the creep temperature of alloy steel pipeline is about 420 ℃, the creep temperature of stainless steel pipeline is about 480 ℃.In this paper, by analyzing the operation conditions of an original high temperature flue gas export pipeline in a petrochemical plant, the pipeline arrangement was optimized by using stress analysis software CAESARII. The safety about the service life of pipeline under the condition of creep was assessed through calculating.
Keywords:CAESARII  Creep  Stress  High temperature pipes  CAESARII
