Canusa Aquashield: Advanced Corrosion Protection for Water Pipelines
is a family of heat-shrinkable sleeve products specifically designed to provide long-term corrosion protection for large-diameter water pipelines. Manufactured by Canusa-CPS (who is owned by Seal for Life Industries), these sleeves are trusted worldwide for their robust performance, ease of installation, and compliance with industry standards.
sleeves use a cross-linked polyolefin backing combined with a heat-activated adhesive. This combination ensures a strong bond to both metallic pipe surfaces and common pipeline coatings, forming a seamless, waterproof barrier that prevents corrosion and mechanical damage.
:
The heat-activated adhesive forms a continuous, moisture-proof seal with the pipe and adjacent coatings, while the tough cross-linked polyolefin backing shields against physical and chemical damage.:
The high-performance crosslinked backing offers exceptional abrasion resistance and mechanical strength, critical for water pipelines exposed to challenging environments.:
Aquashield sleeves provide long-term protection against chemical attack, safeguarding pipelines from aggressive soils and water-borne contaminants.:
Unlike some traditional coating systems, Aquashield sleeves do not require special primers, simplifying installation and reducing labor time.:
: Custom-cut for field joints, “O”-ring, and field-welded connections, as well as fittings and mitered elbows.
: High-expansion, high-recovery system for flanges and high-profile joints, featuring skirting sleeves for bolt protection.
: A two-layer system (underlay plus heat-shrink sleeve) for extra protection at internally welded joints and weld-after-backfill applications.
:
Aquashield products meet or exceed the requirements of AWWA Standard C216-15 for heat-shrinkable cross-linked polyolefin coatings, ensuring compliance with industry benchmarks for water pipeline protection.

Aquashield is engineered for large-diameter water pipelines, including both transmission and distribution line.
The heat-activated adhesive forms a continuous, moisture-proof seal, while the cross-linked polyolefin backing provides a robust barrier against physical and chemical damage.
No special primer is required, streamlining installation and reducing project time.
Aquashield AQW-HS and AQW-WAB products comply with or exceed AWWA C216-15 standards for exterior coatings on pipeline special sections, connections, and fittings.
Yes. AQW-HS is for standard joints and fittings, AQW-FPK is for flanges and high-profile joints, and AQW-WAB provides extra protection for weld-after-backfill and internally welded joints.
The sleeve is wrapped around the prepared pipe joint and heated, causing it to shrink tightly and the adhesive to bond, forming a durable, seamless protective layer.
| Feature | Benefit |
