AI Technical Summary
Technical Problem
The welding connection strength of the plastic inner liner is poor after being manufactured in sections, which affects the sealing and overall performance of the gas storage cylinder.
Method used
A gas storage structure is designed, including a straight section and a head section. By setting step surfaces and slopes at the ends of the straight section and the ends of the head section, and performing specific welding methods, the connection area and welding strength are increased.
Benefits of technology
The welding strength and sealing between the straight section and the head section are improved, the wall thickness of the gas storage structure is reduced, the volume is increased and the weight is reduced.
