Warm-Applied Corrosion Prevention Shrink Sleeves

For Operating Temperatures up to 50°C | Field Joint Protection for Buried Pipelines

Our Warm-Applied Corrosion Prevention Shrink Sleeves are a reliable, field-applied solution for the protection of welded field joints on buried pipelines operating at temperatures up to 30°C. Each sleeve consists of a cross-linked and stabilised polyethylene (PE) backing coated with a butyl rubber adhesive, providing a durable, watertight seal that protects against corrosion, moisture ingress, and mechanical damage.

The sleeves are designed for on-site application, making them ideal for pipeline construction and maintenance projects where field conditions require a practical, dependable solution. In addition to field joint protection, they are also suitable for the repair of mechanical defects in PE or PP factory coatings.

The cross-linked PE backing provides the necessary shrink force and thermal stability during warm application, while the butyl rubber adhesive offers excellent conformability and long-term sealing performance.

• Welded field joints on buried pipelines – Corrosion protection at girth welds

• Repair of mechanical defects – Restoration of damaged PE or PP factory coatings

• Low-temperature pipeline service – Operating temperatures up to 30°C

• On-site pipeline construction and maintenance – Field application without specialized equipment

• Water and gas transmission lines – External corrosion protection in buried service

Surface Preparation: Clean the steel surface and adjacent plant coating to remove loose rust, dirt, oil, and contaminants. Surface should be dry and frost-free.

Preheat (as required): Apply gentle warmth to the steel surface to the manufacturer’s recommended temperature.

Position Sleeve: Wrap the shrink sleeve around the joint, centering over the weld with equal overlap onto the plant coating on both sides.

Apply Heat: Apply warm air or gentle heat uniformly to shrink the backing and flow the butyl rubber adhesive, ensuring a tight, watertight seal.Inspect: Verify complete shrinkage, adhesive flow, and absence of voids or lifted edges.
