About ISOFLANGES

ISOFLANGES GmbH develops and manufactures high-performance isolating flange connections as well as related connection solutions for energy suppliers, transmission pipeline network operators, distribution network operators and municipal utilities, chemical and petrochemical companies, and cathodic corrosion protection (CCP) specialist firms. The portfolio ranges from standard designs to custom-made solutions for demanding pressures, diameters and media – from classic natural gas to 100% hydrogen or CO₂. The solutions include electrical isolation and CCP concepts, code-compliant design in accordance with DVGW, DIN EN and ASME, and complete project documentation from design through to acceptance. In addition, the company offers technical consulting, training, certified inspection reports and support in detailed engineering, for example with special constructions or the replacement of underground insulating couplings with accessible, testable systems. Reference projects include, among others, CCP isolating flanges for the GDRMA Schwaig (N-ERGIE Netz), the Heide refinery, a hydrogen-capable gas pressure regulating and metering station of NOWEGA in Bad Bentheim, the large-scale Huntorf H₂ storage facility, the Ritom power plant, and the Porthos CCS project in Rotterdam. The depth of development and manufacturing is designated 'Developed in Germany / Made in Germany'.
