Energy and Utility Infrastructure Gaskets for gas and water distribution, power generation, and power plants.

Designed to meet the regulatory requirements of critical utility infrastructure and demanding operating conditions. With verified performance data, standard-compliant design, and project specific validation, we ensure permanent leak-tight connections in networks, facilities, and power plants.

Challenges in utility infrastructure #

Gaskets in gas, water, and energy systems are not standard components, but rather safety-critical parts that must meet regulatory requirements, durability testing, and ensure complete batch traceability. With increasing pressure from laws, gas and water regulations, verifiable quality is becoming a must.

Critical requirements in practice #

  • Lightning current carrying capacity according to DIN 30691

  • Batch traceability according to DIN 30690-1

  • DVGW-G 491-compliant equipotential bonding

  • Media resistance [natural gas, drinking water, H2]

  • Suitability for corrosive and cryogenic media

  • Test reports from accredited institutes [e.g., BAM]

  • Gas tightness

  • Standard-compliant labeling and documentation

  • Risk reduction under alternating loads and/or pressure surges

Our solutions #

Standard-compliant. Documented. Ready to ship. #

We don’t just supply the gasket—we provide complete verification: tested in accordance with current regulations, traceable down to the batch, and with the option for mathematical verification. For operators of critical infrastructure who require safety.

Material Verification By Spectral Analysis
RTJ gaskets made of modified soft iron as documented alternative to galvanized 1.0335. Corrosion protection via a special oil as an alternative to galvanization/chromating.

BAM Test Report
Batch-specific test reports from the Federal Institute for Materials Research and Testing for adhesive-free LE-Safe gaskets.

DIN EN 1591-1 Engineering
Standard-compliant flange calculations with strength and leak-tightness verification available as a service—as well as in-house engineering for project-specific designs.

DIN 30690-1 Traceability
Seamless batch traceability throughout the entire life cycle—for audits, operation, and in the event of damage.

Leakage Characteristics H2
Advanced Products with leakage characteristics in accordance with DIN EN 13555, supplemented by H2 values.

DIN 30691 Lightning Current Carrying Capacity
Tested lightning current carrying capacity according to a newly developed standard procedure [Edition 2024-12]—reproducible and documented.
