Product Overview
Hotmelt Adhesive Heat Shrink Wrapid Tape is a high-performance corrosion protection solution designed for pipeline joints, field repairs, and girth weld coatings. Utilizing advanced radiation cross-linked polyolefin backing and a specially formulated hotmelt adhesive system, it provides a seamless, waterproof barrier against corrosive elements in oil & gas, water, and chemical pipelines.
Key Features & Benefits
- ✔ Superior Corrosion Protection
- Forms a permanent, monolithic barrier with >99% water resistance (tested per ISO 21809)
- Excellent resistance to cathodic disbondment (
- ✔ Engineered for Field Efficiency
- Fast Installation: Shrinks uniformly at 120-150°C with propane torch (1-2 minutes per joint)
- Self-Repairing Adhesive: Fills irregularities up to 3mm during heating process
- UV Stability: 12-month outdoor exposure resistance without degradation
- ✔ Material Science Innovation
- Backing: 3-layer co-extruded polyolefin (2.5mm nominal thickness)
- Adhesive: Butyl rubber-based hotmelt with 85% solids content
- Operating Range: -50°C to 110°C continuous service
Technical Specifications
| Parameter | Value | Standard |
|---|---|---|
| Peel Strength | ≥80 N/cm | ASTM D1000 |
| Dielectric Strength | ≥30 kV/mm | IEC 60243 |
| Impact Resistance | 10J at -30°C | ISO 21809-1 Annex G |
| Soil Stress Resistance | 1.5N/mm² after 30 days | DIN 30672 |
Typical Applications
- Pipeline Construction: Girth weld coating for 3LPE/3LPP pipes
- Repair Systems: Damaged coating rehabilitation (compatible with FBE/PU)
- Specialty Uses: Offshore risers, directional drilling entry/exit points
Why Our Solution Stands Out
- Factory-Direct QC: Every batch undergoes:
- 100% holiday detection (≥2500V DC)
- Adhesion testing on grit-blasted steel (Sa 2.5)
- Global Compliance: Pre-qualified for:
- ISO 21809-1 Annex B
- AS/NZS 4352
- DNV-RP-F102
Available Customizations:
- Widths: 100mm to 1500mm
- Adhesive variants: Conductive/High-temperature (up to 150°C)
