CANUSA CanusaTube™
PLA
Pipeline Sleeve
Tubular sleeve for
pipeline corrosion protection
 Product Description
The CanusaTube™ is a heat shrinkable tubular sleeve
designed for corrosion protection of buried and exposed steel pipelines. CanusaTube™
consists of a crosslinked polyolefin backing, coated with a protective heat sensitive
adhesive which effectively bonds to steel substrates and common pipeline coatings
including polyethylene and fusion bonded epoxy.
Features & Benefits
Rapid & Reliable Installation
Because CanusaTube™ consists of a unique tubular
configuration that has been factory constructed, quick and reliable field installation is
easy to accomplish. CanusaTube™ is available with a specially formulated adhesive to
accommodate demanding operating temperatures and soil stress conditions. To further
optimize installation, CanusaTube™ is available in yellow, which includes a
thermochromic indicator to visually confirm proper installation.
Long
Term Corrosion Protection
CanusaTube™ provides excellent
resistance to cathodic disbandment resulting in effective long term corrosion protection.
The high performance crosslinked backing in combination with the specially formulated
adhesive is engineered to have excellent resistance against temperature cycling, and
chemical and environmental attack.
Saves Time & Money
With CanusaTube's™ unique
construction, less time is required handling, positioning and installing separate
closures. With the application of heat, this feature allows for fast, simple and complete
installation of the sleeve. No additional costly primers are required. This minimizes
installation time and labor costs while promoting high production rates. CanusaTube™
is also available in a high shrink ratio for high profile joint protection. Consult the
High Shrink data sheet for additional information.
