Special advantages

Designed for corrosion protection of main pipelines of large nominal sizes.
Maximum mechanical and corrosion protection combined with outstanding tape flexibility.
Self-amalgamation (mixing) of the tapes in the overlap area forms an impermeable sleeve-like coating.
Virtually impervious to water vapor and oxygen.
Compatible with factory coated PE.
DK-BUT® tapes are easy to apply by hand.
To ensure a quality and more efficient application, it is recommended to use original winding devices DK-WORKER®.


Area of application

icon Gas pipelines icon Oil pipelines icon Plumbing icon Repair and restoration icon Protection of welded joints

System DK-BUT®2426 is a proven solution for the permanent prevention of pipe and weld corrosion in areas of increased risk of corrosion in new installations or refurbishment projects.

System DK-BUT®2426 self-amalgamation, self-mixing ability in the overlap area creates a completely sealed impermeable sleeve-like coating.

System DK-BUT®2426 is the ideal choice for pipes with both small and large nominal sizes.
