摘　　要：研究了充装SNG的CNG气瓶在450d后各种性能的变化,多种橡胶、塑料和金属在SNG中浸泡450d后的质量、尺寸及外观变化。试验结果表明:SNG对CNG气瓶的腐蚀性影响很小,可以安全使用;SNG对各种橡胶的溶胀性影响都在相关标准的规定内,满足实际需求;SNG对各种塑料的溶胀性几乎无影响;SNG对各种金属的腐蚀性影响很小,可以忽略不计。The changes of the various properties of CNG cylinder filling SNG and the mass,dimension and appearance of elastomers,metals and plastics immersing in SNG are investigated after 450 days.The test result indicated that：the corrosive effects of SNG on the CNG cylinder are very small,can be used safely; swelling effect of SNG on all kinds of rubber is in the provisions of relevant standards,can meet the actual demand ; little influence was found on all kinds of plastic for SNG on swelling properties; the corrosive effects of SNG on various metals can be ignored.
