摘要
总结了液氢储运系统用管材的开发难点和技术需求,介绍了其设计理念和制备工艺,分析了3种液氢储运系统用管材的-269~20℃冲击性能和低温拉伸性能.通过数据汇总、归纳和线性分析,得到-269℃低温冲击和低温拉伸经验公式.3种液氢储运系统用管材在极端低温条件下仍具有卓越的抗脆断能力和冲击性能,完全满足液氢储运装备对材料低温韧性的严苛需求.成功开发的液氢储运系统用特种不锈钢材料,为液氢工厂、储运罐车、杜瓦罐的选材提供了指导.
Summarize here in the essay are the difficulties and the technical demands concerning the development of the pipe for liquid hydrogen storage and transportation system.Also described are the design concept and manufacturing process of the said system.The impact energy at-269~20℃and the low temperature tensile property of three types of the pipe as used for the said hydrogen system are analyzed.The empirical formulas of the-269℃impact energy and the low temperature tensile are obtained via data summary and induction,and linear analysis.The three types of the pipe as used for the liquid hydrogen storage and transportation have outstanding fracture resistance and impact energy,having been co-mpletely in conformance with applicable strict requirements for low-temperature toughness of the pipe as used for the liquid hydrogen storage and transportation system.The successful development of the special stainless steel tubular goods provi-des a guidance for selection of materials to be used for the liquid hydrogen plant,the tanker truck and the Dewar flask,etc.
