Hotmelt Adhesive Heat Shrink Wrapid Tape For Joint Wrap Coating

Hotmelt Adhesive Heat Shrink Wrapid Tape for Joint Wrap Coating

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 (<5mm at 65°C per NACE TM0316)

✔ 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

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?

1. Factory-Direct QC: Every batch undergoes:

   • 100% holiday detection (≥2500V DC)

   • Adhesion testing on grit-blasted steel (Sa 2.5)

2. 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)
