論述了蒸汽冷凝液管道運(yùn)行現(xiàn)狀,分析了發(fā)生泄漏的原因。通過(guò)對(duì)管道進(jìn)行重新選材、優(yōu)化設(shè)計(jì)、規(guī)范操作,削弱了流體、應(yīng)力、缺陷等內(nèi)外因素對(duì)管道的不利影響,降低了蒸汽冷凝液管線泄漏現(xiàn)象的發(fā)生概率,取得了較好的經(jīng)濟(jì)和社會(huì)環(huán)境效益。

There is a large number of saturation vapor pressure equations used to calculate the pressure of water vapor over a surface of liquid water or ice. This is a brief overview of the most important equations used. Several useful reviews of the existing vapor pressure curves are listed in the references. Please note the updated discussion of the WMO formulation. 1) Vapor Pressure over liquid water
