随着世界范围内电子、化工、医药、航天等用气行业的快速发展,电子级高纯及高腐蚀气体(以下简称特种气体)的需求量不断增加。因此,对盛装特种气体的包装物洁净度的要求越来越高。作为特种气体包装物——高压大容积无缝清洁气瓶的需求也成为必然。截止目前,国外仅有少数几家生产和销售盛装特种气体的高压大容积无缝气瓶,数量少、价格高。国内盛装特种气体的气瓶多按GB5099《钢质无缝气瓶》标准制造的40L~80L小气瓶,存在诸多问题:使用过程中需频繁
With the rapid development of the gas industry in the world such as electronics, chemical industry, medicine and aerospace, the demand for electronic grade high purity and highly corrosive gas (hereinafter referred to as special gas) is continuously increasing. Therefore, the requirements for the cleanliness of packages containing special gas are getting higher and higher. As a special gas packaging - high-pressure large-volume seamless clean gas cylinder needs also become inevitable. Up to now, there are only a few overseas high-pressure and large-volume seamless gas cylinders for special gas production and sales with a small number and high prices. More domestic special gas cylinders GB5099 “steel seamless gas cylinder” standard manufactured 40L ~ 80L small cylinder, there are many problems: the use of frequent
