“低温低应力工况”下管道材料的应用

Applicationof Piping Materials under “Low Temperature and Low Stress Conditions”

通过对国内外标准中“低温低应力工况”定义的比较,选择合适的低温低应力判定准则,对该判定准则建立相对应的模型并进行详细分析和计算,据此制定合理的选材方案。

By comparing the definitions of “low temperature and low stress conditions” in domestic and international standards, the appropriatecriterion of low temperature and low stress is selected, and the corresponding model is established, analyzed and calculated in detail. Based on this, a reasonable material selection scheme is made.
