This paper presents some concrete practice of the technical tests performed by the authors during these years, which include almost all the safety performance tests of the imported CO, cylinders. Some differences between the national standard GBl1640- 89 and the external standards in these technical tests are also pointed out. It provides reference to the further perfection of the safety performance test standard of aluminum gas cylinders.
In this paper,the CAD software of wire-wound ultrahigh pressure vessel is developed using Visual Basic.By using advanced design methods such as parameterization and object-oriented methods,the structure design and strength computation are combined.It simplifies the complicated design process and the computations can be checked and revised conveniently.The software is with better intelligence.
