苯加氢高温临氢管道服役十年后的安全状况研究(一)──工艺管线及炉管选材

Safety Situation Evaluation on the High Temperature Hydrogen Exposure Piping after Served ten Years Part One:Material Selection for Piping and Furnace pipe

本文分析了某化工公司从日本引进的苯加氢装置高温高压临氢管道及加热炉炉管的选材以及运行情况。与石油炼制中临氢管道相比，该装置中管道操作温度更高，对材料选择要求也更严。

The material selection and service condition for high temperature hydrogen exposure piping and furnace pipe was analyzed for one chemical plant imported from Japan.Compared to the hydrogen processing piping in oil refinery, piping in this chemical plant operated at higher temperature. Therefore the material served in harsher terms
