Cryogenic Transition Joints for LNG & Hydrogen
LNG and liquid-hydrogen systems often join aluminium heat exchangers and tanks to stainless-steel piping — a joint that cannot be fusion welded. CryoClad® solves this with a multi-layer transition joint made by vacuum explosion welding, hermetic and reliable through repeated cryogenic cycles.
Applications
- LNG liquefaction and regasification plants, FLNG and FSRU
- Aluminium plate-fin and coldbox heat exchangers connected to stainless piping
- Liquid hydrogen storage and transfer
- Aerospace and high-vacuum systems
- LNG tankers (also with Inox-Triplate®)
Proven performance
- Helium leak tested down to 10⁻¹⁰ mbar·l/s
- Pressure resistance above 360 bar
- 100% dye penetrant inspection of the bond interface
- Stainless 316L/304L base with titanium or silver barrier layer, Al 1050A and Al 5083
Frequently Asked Questions
How do you weld aluminium to stainless steel in LNG systems?
With a transition joint such as CryoClad®. Each side is welded conventionally to its own metal, while the explosion-welded interface joins the two permanently.
How is hermeticity verified?
Every CryoClad® plate is helium leak tested down to 10⁻¹⁰ mbar·l/s and dye penetrant inspected.
Is CryoClad® suitable for liquid hydrogen?
CryoClad® is designed for extreme cryogenic and vacuum conditions, including hydrogen applications. Contact us with your design conditions.
