Kebutyl-System C 50 C

The Kebutyl-System C 50 C is a cold applied two-tape system designed for corrosion protection of pipelines according to DIN EN 12068 (class C 50), DIN 30672 (class C 50) and ISO 21809-3 type 12А-1 (Тmax 50°C). It consists of the adhesion-promoting Kebutyl-Primer K III, the 3ply Kebulen-Tape 1.2 H (inner layer) and the Kebulen-Tape PE 0.50 (outer layer). The Kebutyl-System C 50 C fulfils the requirements of load class C at a maximum continuous operating temperature of 50°C.

The Kebutyl-System C 50 C so called "Ruhrgas System" has been developed in the 1980s together with the technical department of the former Ruhrgas Company. It is a cold applied corrosion protective system used for the coating of buried or immersed steel pipelines. The Kebutyl-System C 50 C is used for the site applied coating in the area of the welded seam also for pipeline coating. The Kebutyl-System C 50 C is compatible with factory coatings of PE, PP, epoxy resin, PU and bitumen. It can be used for Field Joint Coating, Coating Rehabilitation and Coating Repair
