空分装置在低温下工作,为了保证管系的安全可靠运行,有时必须设置管道支架;若管架设计不当反而对管道形成限制,将带来不利的结果;此时管架合适的受力释放不仅可以满足管道应力分析要求,而且使管道不增加材料情况下,改变受力状态,进而满足安全运行要求。 Air separation plant work at low temperatures, in order to ensure the safe and reliable operation of pipe systems, and sometimes must be set up pipe brackets; if not properly designed pipe rack but the formation of restrictions on the pipeline, will bring adverse results; Not only to meet the requirements of pipe stress analysis, but also to increase the material without pipe conditions, changing the state of stress, and thus meet the safety requirements.
