高温临氢管道材料的损伤和安全评估

Damage and Safety Evaluation of Pipeline under Elevated Temperature Hydrogen Environment

本文通过对退役不锈钢管道的取样测试 ,进行了材料的化学成分的检验、金相组织的分析、材料室温和高温条件下主要力学性能的测试。结果表明 ,主要性能指标仍符合规范和标准的要求 ,该管材在目前工况下还可继续使用。

In this paper,tests are carried to measure chemical ingredient,determine mechanical property under room temperature or elevated temperature and metallographic phase has been examined by samples from an ex-service stainless steel pipeline.It has been shown that the main properties are still in the scope of safety standards and the pipeline can be continued to operate.
