Aqua-Shield

Corrosion protection sleeves for water pipelines

Aqua-Shield™ is a family of heat shrinkable sleeve products that have been specifically designed for the corrosion protection of large diameter water pipelines.

Various product configurations are available that utilize a cross-linked polyolefin 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 cross linked 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: The AQW-WAB system is a two layer system comprised of a 6” wide AQW-WAB underlay sleeve followed with the secondary AQW-HS heat shrink sleeve for added protection over the heat affected zone for internally welded field joints / weld-after-backfill applications

Assured Performance

  • The AQW-HS and AQW-WAB products meet and exceed the requirements of AWWA standard C216-15
