采用大容积钢制无缝气瓶输送压缩天然气等工业气体的长管拖车在我国应用越来越广泛。为定量了解我国长管拖车应用现状信息,对2004年至2012年期间开展定期检验的长管拖车进行了统计分析,共涉及3070辆长管拖车和25739只长管拖车气瓶。针对长管拖车气瓶外螺纹磨损严重的问题,依据统计数据,从气瓶使用地域、瓶口外螺纹结构、气瓶布置位置等方面,对气瓶瓶口外螺纹磨损原因进行了初步的讨论和分析,可为气瓶外螺纹磨损机理的进一步研究提供一定的参考价值。
The use of large-capacity steel seamless gas cylinders to transport compressed gas and other industrial gas long tube trailer is more and more widely used in our country. In order to quantitatively understand the current situation of the application of long-tube trailers in our country, a statistical analysis was conducted on the long-tube trailers carrying out regular inspection between 2004 and 2012, involving a total of 3,070 long tube trailers and 25,739 long-tube trailer gas cylinders. According to the statistical data, the causes of the external thread wear of the cylinder bottle mouth are discussed and analyzed from the aspects of the cylinder area, the external thread structure of the bottle mouth and the location of the gas cylinder. , Which can provide certain reference value for the further study of wear mechanism of cylinder external thread.
