What is Cryogenic & LNG Components?
❄️ Cryogenic & LNG Components represents a complete system of precision titanium components engineered for Energy applications. Valve bodies, stems, seal rings, piping, bellows — often with extended stems for cold box penetration The system integrates 0 distinct component types manufactured through 3 specialized processes.
Engineering & Design Principles
Material: Grade 1 (CP-Ti) has excellent cryogenic toughness (KV >60J at -196C) and low thermal conductivity, making it ideal for LNG and liquid hydrogen service.
Form: Bar stock for valve stems and small components. Plate for flanges and valve bodies. Tube for piping.
Standards & Material Specifications
Standards: ASTM B348 Grade 1, annealed, Charpy V-notch tested at -196C (min 27J), helium leak tested

1 Part Feature Analysis
Extended valve stem, cold box piping, pressure vessel internals, seal housings, bellows
- ⚠️ Brittle fracture at cryogenic temperature
- ⚠️ Thermal contraction/expansion
- ⚠️ Leakage through seals at low temperature
- ⚠️ Ice formation on moving parts
2 Material Selection Rationale
Grade 1 CP-Ti — Pure Ti, highest ductility
Grade 1 (CP-Ti) retains ductility and fracture toughness at cryogenic temperatures down to -253°C (liquid hydrogen). No ductile-to-brittle transition like ferritic steels. Grade 5 for higher strength components.
3 Form Selection Rationale
Round Bar / Rod — for turning, fasteners
Bar stock for valve stems and machined components. Seamless tube for cold box piping. Forged rings for cryogenic valve bodies.

Process Pitfalls:
- ⚠️ Valve stem extension length must account for thermal contraction of 0.2% from ambient to -196C
- ⚠️ Seal materials (PCTFE, PEEK) must be qualified for cryogenic service
