介绍了化学注入药剂在平台管道正常运行中的重要地位以及实际应用价值,重点阐述了化学药剂注入件对整个系统的影响,并提出了对于注入件强度和寿命的校核方法,详细的进行了计算原理讲解和方法介绍,并以某设计项目为例对化学药剂注入件插入管道中的部分进行应力分析以及动态计算,针对未能符合要求的计算结果,提出整改建议,给出方案进行修改,使其能够满足设计要求。并在文章的最后对化学药剂注入系统的相关计算进行了总结,为以后的工作给出指导。
The importance of chemical injecting agent in the operation of platform pipeline is introduced, and its practical application value is introduced. The influence of chemical injecting component on the whole system is mainly described. The method of checking the strength and life of injecting component is put forward in detail. Calculation principle and introduction of method. Taking a design project as an example, the stress analysis and dynamic calculation of the part inserted into the pipeline by chemical injection are put forward. According to the calculation results that fail to meet the requirements, the suggestions for rectification are given, the scheme is modified, So that it can meet the design requirements. At the end of the article, the related calculation of chemical injection system is summarized, giving guidance for future work.
