管道抗热应力的措施

Measures for Thermal Stress Resistance of Pipeline

简要介绍加氢装置中的氢腐蚀类型,着重阐述了在某加氢管道中存在的热应力情况以及该热应力对管道系统的危害。探讨了在使用CFD模拟软件分析后,通过在加氢管道内部添加衬里管道作为保护手段,从而抵抗加氢装置中的热应力腐蚀裂纹。

Introduced the hydrogen corrosion types in hydrotreating unit, focused on the thermal stress in a hydrotreating pipeline and its damage to the pipeline system. After simulation and analysis by CFD. adding a liner in the hydrotreating pipeline to resist the condosion cracking caused by thermal stress.
