摘　　要：扁平绕带式高压容器是中国首创的高压容器结构 ,具有设计灵活、结构合理、制造简便、安全可靠等特点。初步的研究分析表明 :将其应用于低温领域时 ,具有较高的抗低温脆性断裂的能力 ;其端部斜面焊缝结构的抗疲劳强度比对接焊缝结构高 ,且不会发生一次性脆性破坏 ;同时容器也具有足够的抗疲劳能力。Flat steel ribbon wound pressure vessel was originated in China. The design of the vessel was is flexible. The construct is proper. The manufacture is easy. The vessel is reliable. In application in the cryogenic field, the vessel could prevent from the low temperature brittle fracture. The fatigue resistance of the scarf weld in the end of the vessel is stronger than that of the butt weld. At the same time, the brittle fracture caused by primary stress will not happen.
