Overview

Structural strength. Verified.

The H2 Burst Test Machine validates the structural strength of hydrogen fuel-system pressure components by hydrostatic proof, holding and burst-pressure testing. Controlled pressure up to 3500 bar using water/DI water records test pressure, pressure-time graph, burst pressure and certification data for traceable reporting.

Liquid pressure testing: lower stored energy, safe testing, full structural validation to 3500 bar.

For hydrogen component burst testing, liquid pressure testing is recommended instead of gas burst testing because liquid media stores significantly lower energy. The system includes pressure generation and control unit, pre-filling pump, PLC-based electrical control, laptop/HMI operation, safety interlocks, tower light indication and pressure test chamber.

Hydrogen components covered: Check valve, manual valve, manual cylinder valve, automatic valve, pressure indicator, pressure regulator, pressure relief valve, excess flow valve, PRD/TPRD, flexible fuel line, rigid fuel line and fittings — as per ISO 12619 Parts 3–16.

Pump stages: Low-pressure pump 4–25 bar (ratio 1:4); medium-pressure pump 26–150 bar (ratio 1:28); high-pressure pump 151–900 bar (ratio 1:151); ultra-high-pressure pump 901–3500 bar (ratio 1:628). Pneumatic-operated pressure generation supports low heat generation and compact design.

Standard Test Process

Load component in chamber and connect to test adapter using rated HP fittings. Fill specimen with water/DI water and remove trapped air through venting. Close and lock chamber door; PLC verifies door, water level and air pressure interlocks. Select test recipe and enter component identification, medium and test pressure. Raise pressure in programmable steps up to proof/HST setpoint. Hold pressure for editable duration at each pressure step. For burst test, continue pressure rise until component failure or maximum pressure limit. Record date, product ID, test fluid, pressure steps, pressure-time graph and certification result. Auto-vent and drain the system after test completion or safety trip.

Chamber Construction

  • Dual-chamber design with intermediate spring acting mechanism
  • Dual safety glass window with intermediate air-pocket design for blast protection
  • MS powder-coated robust construction with industrial chamber light
  • Heavy-duty metallic angle foundation and lifting eye bolts for movement
  • Large front opening for easy loading and unloading of test specimen

Safety Note

This chamber is designed for hydro-burst testing. It is not proposed for pneumatic burst unless specifically redesigned and certified for stored-energy risk. The final chamber design, fixture design, adapter material, high-pressure tubing class and safety validation must be confirmed against the actual maximum pressure, specimen volume, component geometry and customer-specific test standard.

FAQ

Common questions.

Q01 Why use water instead of gas for burst testing?
Water/DI water stores significantly lower energy than compressible gas at the same pressure. This greatly reduces the hazard severity in the event of a component failure during burst testing.
Q02 What is the maximum test pressure?
The machine generates up to 3500 bar using a four-stage pneumatic pump system. An air-side safety mechanism prevents overpressure beyond this limit.
Q03 What components can be tested?
All hydrogen fuel-system pressure-containing components per ISO 12619: check valves, manual valves, manual cylinder valves, automatic valves, pressure indicators, pressure regulators, PRVs, EFVs, PRD/TPRD, flexible and rigid fuel lines, and fittings.
Q04 Can the machine record pressure vs time graphs?
Yes. Pressure vs time graph is recorded for each test. Certification of results can be generated after test completion. Historical test data is retrievable for future reference.
Q05 What safety features does the burst chamber have?
Dual safety glass windows with intermediate air-pocket; automatic door locking; system that inhibits pressure testing if door is open, water level is inadequate or air drive pressure is inadequate; automatic venting on leakage, emergency activation or component burst.
Q06 Who manufactures the H2 Burst Test Machine?
The machine is designed and manufactured by Neometrix Engineering Pvt Ltd, Noida, India.
