CCP Insulation in the Düker Building

In Brunsbüttel, Raffinerie Heide GmbH operates a culvert structure as part of the pipeline and logistics infrastructure connecting the tank farm to the processing facilities. As part of modernization and retrofitting measures, critical pipeline connections were to be designed to meet long-term requirements for safety, corrosion protection, and operational reliability—all while being installed in very confined spaces.

ISOFLANGES supplied custom-designed CCP insulation flange systems for this project, which were specifically engineered to withstand pressure on one side. The combination of a pressure ring and an Insulating ring ensures reliable electrical isolation of the piping systems without requiring additional structural modifications in the already limited installation space of the culvert building. This allows the existing infrastructure to remain operational while also making it future-proof for the ongoing transformation of the energy supply.
