φ914mm cylinder with large water volume, single trailer with 4 pieces cylinders can reach 25m³up. φ914mm cylinder’s units with lower transport costs, ratio of water volume/ weight basically more than 1, the biggest can up to 1.43. φ914mm with fewer numbers of cylinders compared with φ559mm, small sealed interfaces and higher safety factor.


As per ASME Sec. VIII cylinder design, φ914mm cylinder with high safety coefficient, high storage efficiency, can be widely used in natural gas station, Diesel train CNG transformation, marine storage bottles group and other chemical gases such as hydrogen storage.
