OD 279MM SERIES / ISO9809 / CNG SEAMLESS STEEL CYLINDER / TRANSPORTABLEHIGH PRESSUE CNG STORAGE SYSTEM
High working pressure upto 250 bar
Low cost, much more economical
Much lighter than CNG long tube transportation trailer
Easy to install, transportable,much more covenient than long tube trailer
Freely choose any size to get any cascade group
Ideal application for CNG ground storage and transportation applications
HOW TO KEEP QUALITY:
1. Wepurchase the best qualified raw materials:
# # All of the steel tubes are completely custom-made according to our technical requirement, to ensure the best mechanical properties of the CNG cylinder.
# The only Chinese supplier that uses world class brand glass fiber, Owens Corning in USA, to make the outer wrap of CNG type 2 cylinders much stronger than that of other suppliers.
# The only Chinese supplier to import epoxy resin from world famous company The DOW Chemical in USA, due to which CNG -2 cylinders have higher ability of anti-aging, UV resistant.
2. Cylinder bottom thickness measurement and UT detection
International standards only requires to do air-tightness test on cylinder bottom, but our internal QC system requires extra tests to measure cylinder bottom thickness and do UT detection, in order to eliminate any defective cylinder with tiny cracks or thinner wall at the bottom.
3. Wrinkle inspection
Neither international standards nor Chinese standards require to check wrinkles at cylinder neck and bottom area, but our experiences and experiments told us tiny cracks always exist under wrinkles, and crack is the root cause of cylinder leakage and explosion problems. We use endoscope to 100% inspect each cylinder, to eliminate all that to be found with wrinkles.
