The design service life of aluminum bottle should meet the requirements of relevant regulations.

Wall thickness design

The minimum guaranteed yield strength (Re) after heat treatment shall be selected for the wall thickness design of the cylinder, which shall not be greater than 85% of the guaranteed minimum tensile strength (Rg).

The hydrostatic test pressure of aluminum bottle is added 1.5 times of the nominal working pressure PW.

Cylinder design wall thickness S should be rounded upward after calculation with at least one decimal point, and should not be less than 1.5 MMO

Working pressure (15mpa/139bar150bar/200br)

Aluminum bottle end design

The connecting part of aluminum bottle end and cylinder body should be smooth transition, and the end size should meet ISO standard requirements:

The thickness of any part of the aluminum bottle end should not be less than the design wall thickness of the cylinder.

End designs of any shape shall be verified by specified hydraulic burst tests and pressure cycle tests.

Aluminum alloy gas cylinder production process

1. Drawing and drawing method: it is a seamless aluminum alloy gas cylinder made of short thick cup parts after heating and punching aluminum alloy embryo material, which is the main form of seamless aluminum alloy gas cylinder manufacturing in China.

2. Cold extrusion: it is a seamless aluminum alloy gas cylinder formed by cold extrusion of aluminum alloy embryo material and then closed. This processing method is simple, low cost, but requires a large tonnage press.

3. Stamping and drawing method: is the aluminum alloy plate deep punching cup shaped parts, and then the open end of the closed process. This processing method bottle body wall thickness is more uniform, but the material utilization rate is low, the process is complex, the cost is high, so there are fewer manufacturers using this process method.

4. Spinning forming method: is the aluminum alloy plate spinning forming manufacturing cylinder. For aluminum alloy and other materials, spinning can maximize the plastic potential of the material, is more than 70% of the deformation, one loading card spinning can achieve the effect of multiple tensile annealing. So stretch spinning is also one of the processes for manufacturing aluminum bottles, and is especially suitable for small batch production.

This kind of cylinder processed and manufactured by spinning process is called "full spinning cylinder". It is generally of high precision, uniform thickness of bottle body wall, good quality and high blasting pressure.
