Valves and other accessories
These tests consist in demonstrating the ability of valves and other equipment (non-return valves, pressure regulators, safety valves, etc.) to withstand their normal operating conditions.
Why test the performance of valves and fittings?
Whether used frequently or periodically, this equipment can cause gas or liquid leaks and become projectiles.
What are the objectives? Ensuring user safety and equipment performance over the long term.
What tests are performed on valves and accessories ?
Our technicians can perform the following tests :
- Endurance tests
- Helium leak tests
- Proof tests
- Excessive torque tests
- Flame impingement test
- Flow measurements
Most of the tests are carried out in accordance with ISO 10297 and ISO 15996 standards.
We also test the cylinder valve guards
Air Liquide CTE performs the following tests according to standard 11117 :
- Torsion/axial torque tests
- Cylinder drop tests to verify the protection provided by the valve guard
These tests may be conducted :
- At room temperature and down to -20°C
- Up to 2.1 m
We can film drop tests using high-speed cameras.
Our failure analysis activities
Oxygen failures, mechanical failures, lifetime of methane steam reformer tubes, etc.
