CANUSA CanusaWrap™
Wraparound Pipeline
Sleeve
Two-piece protective
bulk roll with separate closure
 Description
CanusaWrap™ is a wraparound sleeve with a separate
closure designed for corrosion protection of buried or exposed steel pipelines. CanusaWrap™ is supplied in bulk rolls consisting of a crosslinked polyolefin backing,
coated with a protective heat activated adhesive. Once installed, the system effectively
bonds and protects steel substrates and common main line pipe coatings including
polyethylene and fusion bonded epoxy.
Features & Benefits
 
Long Term Corrosion Protection
CanusaWrap™ provides excellent resistance to cathodic
disbandment resulting in effective long term corrosion protection. The high performance
crosslinked backing, in combination with a broad range of adhesives, can be engineered for
regular or high stress environments. Once installed, CanusaWrap™ provides the
structural integrity of a seamless tube, and provides the substrate with durable
protection against abrasion and chemical attack.
Flexibility on the Job Site
Since CanusaWrap™ is supplied in bulk rolls,
just-in-time customized lengths can be quickly cut in the field to protect any pipe size.
This flexibility results in reduced inventories and cost savings on the job site.
CanusaWrap™ is also available in a high shrink ratio for high profile joint
protection. Consult the High Shrink data sheet or your Canusa representative for
additional information.
Easy Field Installation
CanusaWrap™ can be installed quickly and easily in
most environments. Since no special taping, priming or operator equipment is required,
product installation is quick and labor costs are kept to a minimum. CanusaWrap™ and
the closure seals are available in yellow with a thermochromic indicator and a patented
Windoweld feature which visually confirms optimum installation.
