Insulating flanges that operate reliably even in extreme applications.
A passion for technology gives rise to solutions that bring people together—today and in the future.
HIGH-PERFORMANCE INSULATING FLANGES AND CONNECTION SOLUTIONS FOR CRITICAL MEDIA AND DEMANDING APPLICATIONS.
We develop and manufacture insulating flange connections for utility companies, pipeline and network operators, chemical and petrochemical companies, and CCP specialty firms that refuse to compromise on the critical interfaces of their facilities.
Our solutions are suitable for all types of media: from conventional natural gas to 100% hydrogen or CO₂—from standard models to custom-engineered solutions.
This is how we help our partners operate their networks and facilities safely—and make them fit for the future, step by step.
- H₂- and CO₂-compatible connection technology, certified
- Electrical Insulation and the CCP Concept, Even at High Pressures
- Design in compliance with DVGW, DIN EN, and ASME standards
- Custom-made products for demanding pressures, diameters, and media
- Complete project documentation—from design to acceptance
Solutions That Prove Themselves in the Field
Our projects speak for themselves—in energy infrastructure, the chemical industry, and future technologies.
Transmission Network OPERATOR: SAFELY INTO THE H₂ FUTURE
For high-pressure and long-distance pipelines that require connection solutions certified for 100% H₂—compliant with regulations, documented, and future-proof even today.
DISTRIBUTION NETWORK OPERATORS AND MUNICIPAL UTILITY COMPANIES: H₂ READINESS IN EXISTING INFRASTRUCTURE
CCP separation, DVGW guidelines, the EU Methane Regulation, and modernization during ongoing operations—we are replacing underground insulating couplings with accessible, testable systems that are already designed for hydrogen today.
CHEMICAL INDUSTRY: PROCESS SAFETY AND CHEMICAL RESISTANCE
Aggressive media, high operating pressures, fluctuating temperatures: Our connection solutions remain permanently leak-tight—with comprehensive documentation for acceptance testing and audits.
ENGINEERING AND SERVICE COMPANIES: DETAILED INFORMATION ON SAFE PROJECTS
You are planning systems with specific requirements and/or heightened documentation requirements. We provide support with detailed engineering and develop solutions that go beyond standard components.
Developed in Germany
We’ll find a solution—or develop a new one for you. Made in Germany.
We support operators, planners, and engineering partners through every phase of a project—with technical consulting, training, certified test reports, and documentation that simplifies the acceptance process.
