In one-tape systems, the BUTYLEN tape takes on both the corrosion protection function and that of a mechanical protection tape.
In a two-tape systems, the tapes each take on one of the functions of corrosion protection and that of mechanical protection.
The corrosion protection tapes comprise of symmetrical and asymmetrical three-ply tapes and butyl rubber tapes.
BUTYLEN-Primers improve the peel strength of BUTYLEN-Tapes on the metal surface and support the corrosion protection performance.
Durable corrosion protection of pipeline components with complex shapes is most reliably achieved by using supple petrolatum tapes that follow the contours of the components.
Petrolatum Mastics are particularly suited to long-term corrosion protection due to their permanently plastic qualities and as a filler for cavities in metallic structures.
