管道绝热是为了满足工艺条件需要和节约能源而采取的必要措施,在石油化工生产装置中非常重要,而其用量的统计却是一个非常繁杂的过程。本文通过引用当量长度概念,并借助 Excel 或者其它编程手段快速、准确统计绝热材料用量的方法,提高绝热材料采购的精度,节约建设投资和人力。%This paper introduces in plant design process,how to bring in the concept of equivalent length to make the calculation result more accurate,and how to use Excellto make the calculation process simpler. It is benefit to optimize the cost and procure.
