HRX19® Weldability
- Minimum threaded connection
- No tube thickness required for thread formation
- Same outer diameter: Large inner diameter and lightweight/compact tube
- High cost-effectiveness and safety in piping construction
- No gas leakage -> Reduced maintenance/repair costs
Special features of HYDREXEL™ (HRX19®) material
HRX19® Tensile Strength and Toughness
- Safe operation and ultra-high pressure/rapid charging possible
- Thin wall tube: compact/light weight and reduced material cost
- Rapid charging of ultra-high pressure hydrogen gas required by US DOE possible (5kg hydrogen gas charging in 200 seconds)
HRX19® Hydrogen embrittlement resistance
- Elongation ratio: in-H2 / in-Air >95%
- Excellent hydrogen embrittlement resistance even at ultra-high pressure (100MPa) and low temperature (-50oC)
- Long-term operation possible -> Reduced maintenance costs
