CanaGas type-4 pressure vessels are made by winding a band of high-strength filament fibres over a proprietary high-density polyethylene (HDPE) liner. Depending on the required operating pressure, our liners are filament wound with either fibreglass or carbon fiber. The filament winding process produces a very consistent pressure vessel which, is lightweight, corrosion resistant and, low-temperature compatible.
The HDPE liner is made 2 meters in diameter by approximately 3.5 meters so that 3 tanks will fit inside of a standard 40-foot shipping container.
These type-4 tanks will not rupture, even if penetrated by a bullet. The helical windings eliminate the potential of crack propagation and therefore rupture. These tanks also have a high level of impact resistance.
