摘要
近年来,随着全球能源问题的日益加剧及节能环保要求的日益严格,天然气获得大力发展和应用。低温鹤管有着安全、方便、灵活、经济等优势,已逐渐取代传统软管成为液化天然气(LNG)转运过程中必不可少的关键设备。介绍了低温鹤管的结构以及在生产过程中的一般工艺流程,对低温鹤管泄漏的危害进行了阐述,并对在生产和装配过程中,能够导致低温鹤管泄漏的原因进行了分析,提出了可通过加强焊接质量管控、提升旋转接头中密封组件的装配质量以及提升法兰装配质量等方法来降低低温鹤管泄漏风险。实践证明,生产工艺流程合理,预防低温鹤管泄漏的方法有效,可以大大降低低温鹤管的生产返修率,提高低温鹤管的生产效率和质量。
In recent years,with the aggravation of global energy problems and the increasingly strict requirements of energy conservation and environmental protection,the natural gas has been vigorously developed and applied.The low temperature crane tube had the advantages of safety,convenience,flexibility,economy and so on,so it has gradually replaced the traditional hose and became an essential key equipment in the process of liquefied natural gas(LNG)transportation.It was introduced that the structure of low temperature crane tube and the general process flow in the production process including the harm of low-temperature crane tube leakage,and the causes of low temperature crane tube leakage in the production and assembly process were analyzed,and we put forward that the risk of low-temperature crane tube leakage could be reduced by strengthening the welding quality control,improving the assembly quality of sealing components in rotary joints and improving the flange assembly quality.Practice proved that the production process was reasonable and the method for preventing the leakage of low-temperature crane tube was effective,which could greatly reduce the production repair rate of low temperature crane tube and improve the production efficiency and quality of the low temperature crane tube.
