| Abstract: | Through comparison of the three well known standards of large capacity seamless steel gas cylinders GB/T 33145,DOT Code (3AAX and Special Permission 8009),ISO 11120,and introduction of the filling regulation in USA for large capacity cylinders,the shortcomings in the unification of safety and economy of domestic large-capacity cylinders are discussed.The necessity of light-weight design for domestic large-volume cylinders is pointed out.The feasible ideas of light-weight design of large-capacity gas cylinder are discussed,including the development of new materials,the adoption of new steelmaking processes and technologies,the adoption of advanced manufacturing methods for large-diameter cylinder pipes. |
| Keywords: | large-capacity gas cylinder light-weight design embrittling gas sulphur hydride stress corrosion hydrogen embrittlement |
