A new, full-scale testing system to subject full cross-section pipeline test specimens in hydrogen environments.
The test system is housed in in an explosion proof Special Environments Chamber to provide a safe testing environment where both non-destructive tests and tests to failure can be conducted with continuous, pressurized exposure to the simulated operating environment.
The full-scale test system will have the following capabilities:
- Specimens NPS 28 (711.2 mm diameter) by 700 mm long or as required
- Continuous pressurized exposure to corrosive environments including liquid, liquids with dissolved gases and non-condensable gases
- Gaseous mixtures containing hydrogen, hydrogen-natural gas blends, hydrogen sulfide or carbon dioxide
- Circulated and controlled liquid environments to ensure uniform and consistent specimen exposure
- Test pressure up to 65.5 MPa (9,500 psig) depending on exposure environment;
- Test temperature 10 °C to 80°C;
- Static or cyclic pressure loading
The setup also includes simultaneous, inline compact tension and four-point bend tests to verify small-scale performance in parallel with full-scale tests.
The full-scale test specimens can include:
- Corrosion wall loss defects
- Crack-like defects including colonies of stress corrosion cracks
- Seam and girth welds
- Dents and gouges
- Bends and buckles
The facility will also accommodate tests of other large equipment such as:
- Valves
- Inline inspection tools
- Wellheads, well casing and downhole tools for storage wells
