设备和管道的隔热计算十分繁琐和复杂，为提高计算效率和计算的准确性，采用经济厚度计算法，编制了一种具有保温、保冷和露点温度校核等多功能的设备和管道隔热计算程序。经过工厂实际应用及与文献数据的比较，证明本程序计算的经济厚度、散热量及外表面温度与实际值相符，可方便、可靠地应用于隔热系统的设计中。 Equipment and piping insulation calculation is very complicated and complex, in order to improve the calculation efficiency and calculation accuracy, the use of economic thickness calculation method, the preparation of a with insulation, cold and dew point temperature checking and other multi-functional equipment and pipe insulation Calculation procedures. After the actual application of the factory and comparison with the literature data, it is proved that the calculated economic thickness, heat output and outer surface temperature of this program are in accordance with the actual values, which can be conveniently and reliably applied to the design of the thermal insulation system.
