管路公称压力分子式：CAS号：性质：管路包括管子、管件、法兰和阀门等。公称压力指在基准温度下管路允许的最大工作压力。为了便于设计和选用管路，将管件、阀门等按公称压力大小划分若干等级。我国分为真空、低压、中压、高压和超高压，从低压(PN2.5～16kgf/cm2)到高压(PN100～1000kgf/cm2)划分12等级。基准温度铸铁体为120℃，碳钢为200℃，合金钢为250℃，国外标准的基准温度与国内不同。美国碳钢阀门为450℃、低合金钢阀门为510℃、高合金钢阀门为525℃，不在基准温度下操作，应参照阀门温压表选择最大允许工作压力。高于基准温度特应降低使用、低于基准温度可提高使用压力。1kgf/cm2=98.0665kPa。
