摘　　要：为了弥补热轧、冷轧等工艺对大口径薄壁气瓶用无缝钢管的加工能力不够或成本过高等不足,开发和完善了热扩加冷拔工艺来制造此类无缝钢管。试验结果证明:用此工艺生产的气瓶钢管可以满足GB 28884-2012的要求,同时也满足客户在性能、尺寸等方面提出的协议要求,可以弥补目前市场中此类气瓶钢管的不足。In order to make up to the hot rolling and cold rolling process for the lack of processing capacity or high cost of seamless steel tubes for large-caliber thin-wall gas cylinders, the technology of thermal expansion and cold drawing was developed and improved to manufacture the seamless steel tubes. The test results prove that： the cylinder steel tubes manufactured by this technology could meet the requirements of GB 28884--2012, and also meet the agreement requirements of customers in performance, dimension and so on, and they could make up for the lack of such gas steel tubes in the market.
