Our products are with the world-leading level in material, design and manufacturing techniques. The properties meet the demand of DOT CFFC，NGV-2：2000，ISO1439：2000 and HSE.
Material
Optimizing the elements in aluminum, the variation of the liner properties is smaller comparing with that of the other company's.
Structure
The change of the thickness on the shoulder improves the fatigue behavior of the liner.
manufacturing
The special treatment of the inner surface of the liner improves the mechanical properties considerably. At the same time, the fatigue behavior of the liner has also been improved due to the reduction of the stress concentration and micro-break on the inner surface.
The products are machined by the CNC equipments to ensure the highest rate of consistency while optimizing quality and performance.
Flow forming technique makes the metallurgical structure more pack. |
