Developed independently by HiFluid Industrial, the Hydrogen Cylinder Hydrostatic Test System fully supports both the internal measurement method and external measurement method required for on-board hydrogen cylinder testing, with test pressures up to ≥ 105 MPa.
The system complies with international standards including GTR13, ECE R134, SAE J2579, ISO 19881, and ANSI/CSA HGV 2. As a core testing solution for ensuring the safety and regulatory compliance of high-pressure hydrogen storage vessels, the system applies precisely controlled hydrostatic pressure and utilizes a high-accuracy volumetric measurement system to perform periodic inspections and factory acceptance tests for Type III and Type IV hydrogen cylinders used in fuel cell vehicles, hydrogen storage, and hydrogen distribution applications.
Through overpressure testing, this system provides a comprehensive verification of the cylinder’s overall strength, sealing performance, and structural integrity. During the test, the system precisely measures the volumetric expansion of the cylinder—an essential criterion for evaluating whether the filament-wound layer has experienced irreversible damage or whether the liner has undergone plastic deformation.
