Description
ленне насыщенного пара над рабочей средой будет равно или отличатьс на незначительную величину от давлени насыщенного пара агрессивной жидкости во всем интервале рабочих температур.In the absence of saturated steam over the working medium, it will be equal to or slightly different from the saturated vapor pressure of the aggressive liquid over the entire range of operating temperatures.
По предлагаемому сно,собу испытани химической устойчивости конструкциойных материалов и защитных .покрытий можно проводить до температур, при которых разность давлений на внутравнюю и наружную стенки сосуда не превышает значен ий, допускаемых прочеостными СВОЙСПЕЛМИ матер.иала сосуда.According to the proposed procedure, the chemical stability of structural materials and protective coatings can be carried out up to temperatures at which the pressure difference between the inner and outer walls of the vessel does not exceed the values allowed by the relative strength of the vessel.
