Reference Object No 2 |
The exposure to the coastal climate at the Brunsbüttel terminal on the Elbe estuary doesn’t lead to heavy corrosion attack only on crude oil pipelines (see Reference Report No. 7). Also other constructions are continuously suffering from corrosion, e.g. a railroad bridge leading over an oil pipeline. As a result of good experience with CORRPASSIV® 4906 the responsible authorities decided to also use this CORRPASSIV® system for refurbishing the bridge.
It has been developed for use in heavy-exposure situations such as steel and hydraulic construction, port installations, refineries, bridges, pipelines or containers. The work was carried out by KorroService, Korrosionsschutz- und Reinigungsservice Brunsbüttel GmbH & Co. KG, a corrosion protection and cleaning service.

The complete bridge was fully derusted by sandblasting with blast-furnace grit in accordance with the SIS standard SA 2 ½ for pretreatment. Then the derusted bridge was given a 20 µm coat of CORRPASSIV® Primer to ennoble and passivate the surface.
After a drying time of 3 hours an intermediate layer of two-component epoxy coating was applied in a film thickness of 240 µm. This was followed by an 80 µm film of top coat consisting of a two-component epoxy material pigmented with micaceous iron ore.
