Aqua-Shield Corrosion Protection Sleeves by Canusa-CPS
Description
Corrosion protection sleeves for water pipelines
Aqua-Shield™ is a family of heat shrinkable sleeve products that have been specifi cally designed for the corrosion protection of large diameter water pipelines. Various product confi gurations are available that utilize a crosslinked polyolefi n backing, coated with a protective, heat-activated adhesive which effectively bonds to metallic substrates and common pipeline coatings.
Long Term Protection
- Once installed, Aqua-Shield™ provides durable protection against abrasion and chemical attack. The high performance crosslinked backing provides the superior abrasion resistance and mechanical strength required for water transmission and distribution lines. Aqua-Shield™ effectively covers and protects the pipe surface to prevent corrosion. Since no special primers are required, less time is required for installation.
Flexible & Reliable Installation
- The Aqua-Shield™ family of products are available in various configurations for flexibility of installation.
Aqua-Shield™ AQW-HS: Specially constructed and provided in custom cut lengths for field joints on large diameter water pipelines including “O”-ring and field welded configurations, as well as coating factory fittings and mitered elbows.
Aqua-Shield™ AQW-FPK: A high expansion/high recovery system, designed for corrosion protection and sealing of flanges and other high profile joints. The system includes skirting sleeves to protect flange bolt areas.Aqua-Shield™ AQW-WAB: Designed specifically for “Weld-After-Backfill” applications.
Assured Performance
-
The AQW-HS and AQW-WAB products meet and exceed the requirements of AWWA standard C216-07.
