摘要
关于石油化工管道保冷计算,国家标准及石化相关标准给出的计算公式基本一致,但是计算方法的选用原则并不统一。在实际工程应用中为了能够高效、便捷地计算管道的保冷厚度,文章通过数据对各计算方法进行分析讨论,从而确定最优的计算方法。
In state standard and petrochemical industrial standard, the basic similar equations are used for calculating cold insulation for petrochemical piping. But, the principles for selection of calculation methods are different. In order to calculate the cold insulation thickness of piping with convenience and high efficiency in practical engineering, each calculation method was analyzed and discussed by using data, then the optimum method was determined.
