Engineered for your application
A manual liquid-hydrogen globe reference with a metallic vacuum-insulation jacket and full-penetration welded construction. The extended upper assembly combines a selected bellows and spring-energized sealing system.
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
Technical data
The specification, in detail.
| Parameter | Technical specification |
|---|---|
| Size range | DN 8-100 |
| Pressure ratings | PN50 (5.0 MPa nominal) |
| Temperature range | -253 to +150°C |
| Construction | Manual globe; metallic vacuum jacket; bellows and spring-energized seal |
| Operation | Manual handwheel |
| Medium | LH2 / liquid hydrogen |
Nominal pressure and ASME class are different rating systems. Confirm the pressure–temperature rating for the selected material and design.
End connections
Define the interface.
Shown configuration: a vacuum-jacketed extended globe body, two weld stubs and manual upper handwheel
| Connection detail | Connection / selection requirement |
|---|---|
| Connection options | Weld ends - preparation to specify |
| Mating interface | Confirm end standard, facing or weld preparation, pipe dimensions and installation envelope. |
| Configuration selection | Full-penetration welding describes the construction, not a named process-pipe end standard. Confirm the process and jacket interfaces. |
The illustration shows one configuration. Published connection alternatives are options for enquiry; their availability depends on size, rating, material and design. Installation dimensions come from the drawing, not the illustration.
Materials
From body to seal.
| Component | Material / option |
|---|---|
| Pressure parts and vacuum jacket | Selected metallic material schedule to confirm |
| Seal system | Bellows and spring-energized seals; selected grades to confirm |
Published material alternatives are configuration-dependent. H.F. denotes hard facing; the exact grade and material certificates are confirmed with the offer.
Selection notes
Defined around your application.
- Vacuum-insulated LH2 configuration
- Full-penetration welded construction
- Manual extended upper assembly
| Engineering data | Configuration requirement |
|---|---|
| Insulated interface | Specify process pipe OD/wall, jacket dimensions, vacuum boundary and installation heat load. |
| Qualification | Confirm material schedule, bellows life, leak test, cleanliness and selected order documentation. |
Series limits guide enquiry and are not verified availability or approved operating limits for every size, pressure and operator combination. Confirm the selected design and pressure-temperature rating.
DN8-100 and PN50 describe the product-sheet range; they do not certify every size at every design condition. Type-test family coverage is separate from order-specific documentation.
Published ratings do not establish suitability for every listed medium. Oxygen cleaning, material compatibility, trapped-liquid relief and project approvals are specified for the selected assembly. Liquid-hydrogen and helium service require a separate temperature and material review.
