Wear indicator system for offshore corrosion protection coating systems

Ein Metallrohr, das eine mindestens zweischichtige Korrosionsschutzumhüllung mit einer oberen und einer unteren Schicht besitzt und wobei die untere Schicht so ausgerüstet ist, dass bei einer Beschädigung der darüberliegenden Schicht bzw. Schichten ein optisches oder elektrisches Signal detektiert werden kann, wird zum Einbau in ein Offshore-Bauwerk oder zur Herstellung einer im Wasser verlegten Rohrleitung verwendet. Beschädigungen der Korrosionsschutzumhüllung können damit leicht erkannt und ggf. per Fernwartung gemeldet werden. A metal pipe having an at least two-layer anticorrosive covering with upper and lower layers, and with the lower layer being equipped so that an optical or electrical signal can be detected in the event of damage to the overlying layer or layers, is for installation in an offshore Construction or for the production of a pipeline laid in water. Damage to the anti-corrosion coating can thus easily be detected and, if necessary, reported by remote maintenance.

Polyamide sheathed steel construction tubes for offshore structures

Die Gründungsstruktur eines Offshore-Bauwerks, beispielsweise einer Offshore-Windenergieanlage, besteht aus Stahlrohren, die mit einer extrudierten Schicht aus einer Polyamidformmasse umhüllt sind. Damit wird gleichzeitig sowohl ein guter Korrosionsschutz als auch ein guter Schutz gegen mechanische Einwirkungen gewährleistet, was zu einer deutlich verlängerten Lebensdauer der Gründungsstruktur führt. The foundation structure of an offshore structure, such as an offshore wind turbine, consists of steel tubes encased in an extruded layer of a polyamide molding compound. This ensures both good corrosion protection and good protection against mechanical effects, which leads to a significantly longer service life of the foundation structure.

Steel tubes for offshore structures

Usage of steel tube involves incorporating steel tube having extruded layer of polyamide molded material, into structure of offshore buildings.

Wear indicator system for offshore corrosion protection covering systems

A corrosion protected metal pipe for installation in an offshore structure or for producing a pipeline laid in water is provided. The metal pipe has an at least two-layer covering on the pipe with a lower layer facing the pipe and an upper layer on a side of the lower layer not facing the pipe is provided. The layers are formed such that the lower layer is electrically conductive and the upper layer is electrically insulating, the lower layer is optically contrasting to the upper layer, or the lower layer is electrically conducting and optically contrasting to the upper layer and the upper layer is electrically insulating. Thus, in the event of damage to the layer or layers lying above, a visual or electrical signal can be detected. Damage to the corrosion protection covering can therefore be detected easily and, if appropriate, reported by remote monitoring.
