Aluminum cylinder, oxygen cylinder, gas tank produced in China
alias: Aluminium Oxygen cylinder, Aluminum Oxygen bottle, Aluminum Oxygen tank, Aluminum gas tanks, China gas bottle
Aluminum bottle neck design
The thickness of the bottle mouth should ensure that the bottle mouth will not produce obvious plastic deformation when bearing the upper valve torque and the additional external force of the key collar, and the upper valve torque should meet the requirements.
Bottle thread should run through the bottle; When using taper thread, thread should conform to GB/T 8335; When ordinary thread is used, thread size and tolerance shall conform to GB/T 192.GB/T 196, GB/T 197 or relevant standards. The shear safety factor calculated under hydrostatic test pressure group is at least 10 and not less than 6 teeth.

Aluminum bottle base design

When the aluminum bottle is designed with a base structure, it should ensure that the base has sufficient strength and the base material should be compatible with the material of the bottle body. The base shall be cylindrical in shape and shall ensure the upright stability of the aluminum cylinder. The connection between the base and the bottle body should not be welded, and the structure should not cause water accumulation.

Aluminum gas bottleneck ring design

When the aluminum bottle is designed with a collar, the collar shall be of sufficient strength and the collar material shall be compatible with the bottle material. The collar should not be welded to the bottle body. The axial pull force of the collar shall not be less than 10 times the weight of the empty bottle and not less than 1. 0. N, rotational torque shall not be less than 100 Nmo

Aluminum bottles of cylinder

The bottle body is made of ingot and extruded bar as raw materials by cold extrusion or hot extrusion or cold drawing after extrusion.

The bottle body is made of pipe material by spinning process.

The bottle body is made of sheet metal by stamping, drawing and spinning.

Aluminum cylinder ends

Shoulder can be molded or spinning closing process.

The surface of the transition between bottle mouth and bottle shoulder should be smooth without mutation or obvious wrinkles.

The end should be heated evenly during the forming process to ensure that the material has no over-burning structure.

No welding shall be performed.

Aluminum alloy cylinder group batch

Manufacturing shall be managed in batches, each batch not more than 200 plus the number of destructive test bottles.
