Compact sealing solutions, engineered for reliability in nuclear applications
We offer advanced flanges and sealing solutions specifically engineered to meet the demanding requirements of nuclear applications. Each solution is designed with precision, delivering a lightweight and compact footprint while maintaining performance levels that meet or exceed traditional ASME and API standards.
Our flange technology is optimized for static behavior, providing long-term stability in high-temperature and high-pressure environments, where safety, reliability, and compliance are critical.
Addressing the Nuclear challenge
A well-known flange challenge within nuclear environments is creep and relaxation at elevated temperatures. Our flange technology is specifically designed to address these effects, ensuring dimensional stability, load retention, and leak-free sealing throughout the operating life.
Qualification and in house capabilities
We maintain comprehensive in-house testing and qualification capabilities, enabling validation against nuclear standards and project-specific requirements, including ASME III Division 5, materials testing, stress and strain evaluation, pressure and fatigue testing, high and low-temperature testing, hydrostatic testing, bending, and structural integrity.
Examples on projects we’ve delivered:
- Materials: 316 stainless steel and Alloy 625
- Dimensions: 6” – 10”
- Certification: EN 10204 3.1
Proven high-temperature and pressure performance in Nuclear:
Our solutions are validated for severe nuclear operating conditions, including:
370 °C at 250 bar(g) 585 °C at 193 bar(g) 600 °C at 400 bar(g)

Our internal testing and calculations demonstrate that our flanges remain completely leak-free within a temperature range of -200°C to +500°C.
For applications extending beyond 500°C, specialized design modifications are required to ensure long-term structural integrity and leak prevention. We possess extensive experience in evaluating material creep and thermal stress for flanges exposed to these extreme high-temperature environments.
Yes, up to 750 degree Celsius.
All specifications are according to ASME Section III for nuclear applications, with strict internal control of the supply chain, ID-marking, and QC.
By design, modern nuclear facilities are safe and reliable. This high standard of safety is built on nearly 80 years of operational experience combined with advanced predictive modeling and sophisticated structural analysis.
As a sub-supplier to the industry, we fully understand that the market’s primary ambition is to transition toward factory-built modular fabrication and efficient on-site installation.
Over 30 years of experience in demanding subsea applications provides us with the unique knowledge required to deliver the quality, durability, and robustness needed by the nuclear industry. This allows us to cost-effectively utilize proven competencies and focus on developing standard, high-reliability solutions rather than engineering costly, unproven alternatives from scratch.
In the nuclear sector, “HRS connection flanges” is typically used as a generic term for high-integrity or high-reliability flange systems and single connections. Within our portfolio, our Compact Flanges (CF) and Ultra Compact Flanges (UCF) are engineered with advanced metal-to-metal sealing technology, placing them squarely within this category of high-integrity flange solutions.
