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®-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.
