近年来，随着压力容器管理的规范化和严格化，压力容器安全评定技术日益显示出它的重要性和实用性。压力容器安全评定技术既能为含缺陷容器的安全运行提供科学的依据，又能充分发挥设备的使用潜力。本文论述了含有严重缺陷的移动式空气压缩机气包、ＣＯ饱和塔、合成塔至中置锅炉间高压管线、丁二烯萃取精馏塔的缺陷情况及评定结论，对今后深入开展这方面的工作具有较重要的参考价值。
In recent years, with the standardization and strict pressure vessel management, pressure vessel safety assessment technology has increasingly shown its importance and practicality. The pressure vessel safety assessment technology can not only provide a scientific basis for the safe operation of a container with a defect, but also give full play to the potential of the equipment. This article discusses the defect of mobile air compressor air bag, CO saturated tower, high pressure pipeline between synthesis tower and middle boiler, butadiene extractive distillation tower with serious defects and the conclusion of assessment. In the future, Work has more important reference value.
