摘要
空分装置用来分离空气中的各组分气体,生产氧气和氮气,其离不开低温管道。本文介绍了国内外对低温的界定方法,并阐述了低温管道的材料、分级、配管和保冷措施。
The air separation unit is used to separate each component gas in the air to produce oxygen and nitrogen,which cannot be separated from the cryogenic pipeline.This paper introduced the definition of low temperature at home and abroad,and expounded the materials,classification,piping and cold insulation measures of low tempera⁃ture pipelines.
