To protect against corrosive attack and mechanical damage, coatings or coating systems can be applied depending on application and requirements. Such external coatings reliable, long-term passive corrosion protection.

Internal coatings can provide not only passive corrosion but also a smoother surface finish to reduce the flow resistance for gas pipes. The Salzgitter Mannesmann Großrohr GmbH has its own coating plant for applying coating systems to suit customers’ specification.
The choice of coating system depends on the specific conditions of the application, e. g. operating temperature, soil properties, mechanical loads, etc.
