Insulating flanges
in accordance with ASME B16.5 / B16.47
HP2 provides maintenance-free, safe insulation, high pressure resistance, and complete corrosion protection for gaseous and liquid media—from natural gas to 100% hydrogen and CO2.
General Characteristics: ASME
- For gases classified as G260, including the 5th gas family (≤100% H2, CO2), and liquids with low conductivity
- Technically maintenance-free
- Seal replacement possible; complete insulating flange connection is reusable
- Corrugated ring seals in a positive-displacement configuration; the sealing material does not exhibit flow behavior
- Cleaning-friendly, aerodynamic design
General Characteristics: ASME 5 CCPs
- For gases classified as G260, including the 5th gas family (≤100% H2, CO2), and liquids with low conductivity
- Installation without welding or modifications to the pipe fittings
- With connectors protruding into the pipe cross-section to ensure electrical isolation, without deposits or short circuits
- Technically maintenance-free
- Seal replacement possible; complete insulating flange connection is reusable
- Corrugated ring seals in a positive-displacement configuration; the sealing material does not exhibit flow behavior
Variants
HP2 ASME RF
Applications
- Insulating flange connections for high-pressure pipelines and demanding operating pressures in accordance with ASME B16.5 / B16.47 with RF face profile
HP2 ASME RTJ
Specific Characteristics
- Sealing is achieved not by a soft iron seal ring, but by a corrugated ring seal
Applications
- Insulating flange connections for high-pressure pipelines and demanding operating pressures in accordance with ASME B16.5 / B16.47 with RTJ sealing face configuration
HP2 ASME FF
Specific Characteristics
- Version without compensating rings
- Fewer components, an easy-to-install solution
- Full HP2 block flange functionality
Applications
- Insulating flange connections, e.g., for new construction projects and process plants with flat-face flanges in accordance with ASME B16.5 / B16.47
ASME Custom Designs
- In addition to the versions shown (RF, RTJ, FF), we also supply Large/Small Female and other flange facing options in accordance with ASME standards or customer specifications for any flange and seal geometry.
HP2 ASME RF5 CCP
Applications
- CCP Conversion System for ASME RF Flange Connections as a Replacement for 3–5 mm Flange Gaskets in Oil, Gas, H₂, and CO₂ Pipelines and Process Plants
HP2 ASME RTJ5 CCP
Specific Characteristics
- Sealing is achieved not by a soft iron seal ring, but by a corrugated ring seal
Applications
- CCP retrofit system for ASME RTJ flange connections as a replacement for 3–5 mm flange gaskets in oil, gas, H2, and CO2 pipelines as well as process plants
