- Cantilevering horizontal fixed tooling and continuously solidifying equipment with this tooling (Patent of utility model)

- Ultrasonic testing device (Patent of utility model)

Provides a TR Double crystal probe to process ultrasonic inspection to discover interior disadvantages and ensure there are not any defects in the cylinder.

- Cylinder plate-shaped shoulder forming technique

The first in China utilizing the maximum volume design technology which can enarge the volume in the limited length.

The mostly popular CNG Type 1 cylinders are with the capacity of 80L and 140L. Because of heavy weight, Type 1 cylinders are often used together with Type 2. For instance, a heavy lorry is often fixed with eight Type 2 cylinders of 80L.

The 60L, 65L and 82L CNG Type 2 cylinders are often used on cars, 120L and 140L used on heavy lorries, and 120L on buses, while 200L cylinders often apply to CNG Mobile Storage Trailer.

Compared with Type 1 and 2, the Type 3 cylinders are much lighter, safer, and more energy-saving and can hod more gas. At present we have this kind of cylinder of 120L and we are developing 35MPa hydrogen cylinders.

Self-contained breathing apparatus (SCBA) is aimed to help the people to breathe effectively who are in an oxygen-poor environment or an environment with poisonous gas 2L, 6.8L and 9L are often used.
