DENSOLEN®

DENSOLEN® tapes and tape systems have been used for more than 40 years to provide long-term corrosion protection for buried pipes, welded joints, pipe bends and structural elements.
The invention of the first three-ply composite tape (DENSOLEN®-Tape S40) by DENSO in 1971 was followed about 10 years later by further development to produce the asymmetrical three-ply tapes mainly used today. DENSOLEN® tape systems have been used very successfully in large-scale pipeline construction and in pipeline renovation since 1971. Thanks to constant improvement and the use of modern polyethylene materials, DENSOLEN® tape systems even today represent the state of the art in corrosion protection composite tape.

DENSOLEN® tapes can be combined in various ways to make tape systems. All systems have in common that a self-amalgamating three-ply tape or a butyl tape is always used for the innermost layer of corrosion protection. Only tapes of this type amalgamate in the overlap area to form a sleeve-like coating that is practically diffusion resistant to water vapor and oxygen.
