摘要
简述了国内大容积气瓶用无缝钢管的生产制造情况。介绍了强力旋压工艺的技术特点。进行了强力旋压工艺制造大容积气瓶的应用前景、技术可行性以及经济性分析,指出国内气瓶的容重比和运输效率与国外先进水平相比仍有较大差距,可以借鉴国外先进经验,应用强力旋压工艺,辅助以对轮旋压技术和浮动芯模法生产大直径超长气瓶用无缝钢管,以满足国内不断上升的对轻量化气瓶的需求。
Briefed here in the article is the general situation of domestic production of the seamless steel pipe for the large capacity cylinder.Introduced are the technological characteristics of the powerful spinning process for making such tubes.Also analyzed are the application aspects,technological feasibility and the economy of the said process.It is pointed out that compared with relevant advanced foreign production level of the pipe,there is still a rather large gap in terms of volume-weight ratio and transportation efficiency of the cylinder.To meet the increasing domestic demand for the light-weight gas cylinder it is practical to produce the large-diameter,extra-long seamless steel pipe for gas cylinder serv-ice by means of learning from the advanced experiences of relevant foreign manufacturers,and applying the powerful spinn-ing process with supplement of the opposite roller spinning and floating mandrel techniques.
