针对海上油田上采用的往复式天然气压缩机装置管道系统进行了系统的分析研究,主要是根据设计压力、设计温度、管道内介质的腐蚀性能、管道外环境要求、材料加工工艺性能、焊接性能、合理的经济性或设计寿命等因素来综合考虑。并考虑到在海洋大气环境下的腐蚀状况,对选出材料强度进行了判断。 In this paper, the piping system of reciprocating natural gas compressor used in offshore oilfield is systematically analyzed and studied, mainly based on the design pressure, design temperature, the corrosion performance of the medium in the pipeline, the environmental requirements outside the pipeline, the processing performance of the material, the welding performance, Reasonable economy or design life and other factors to consider. Taking into account the corrosive conditions in the marine atmosphere, the strength of the selected materials was judged.
