Cold Applied Bitumen Tape — Pipe wrapping

1. Product Overview

Cold Applied Bitumen Tape is a self-adhesive, anti-corrosion wrapping system composed of polymer-modified bitumen compounded with a high-density polyethylene backing film. Its primary industrial use is external pipeline corrosion protection for oil, gas, water, and district heating networks. The key value proposition is eliminating hot application (torches or kettles) while delivering cathodic disbondment resistance comparable to fusion-bonded epoxy at half the installed cost. Strategically, it enables rapid deployment in remote or environmentally sensitive areas where heat application is unsafe or restricted, positioning it as the preferred specification for Tier 1 EPC contractors.

2. Key Specifications & Technical Characteristics

• Chemical composition: Polymer-modified bitumen (APP/APAO blend) + HDPE carrier film; cold-flow mastic adhesive layer

• Grade: Industrial heavy-duty, anti-corrosion grade (passes DIN 30672 / EN 12068 standards)

• Physical characteristics: Black; thickness options: 1.1 mm, 1.5 mm, 1.8 mm; width 50 mm to 300 mm; elongation >15%; dielectric strength >30 kV/mm

• Packaging: Spiral-wound plastic cores, shrink-wrapped in moisture-barrier film; palletized 48–72 rolls per pallet

• Shelf life: 24 months in original packaging (5°C–40°C, <75% RH)

3. Core Industrial Applications

• Primary industries: Oil & gas transmission, water/wastewater utilities, district energy, chemical processing, offshore platform risers

• Specific use cases: Field joint coating over FBE or 3LPE; repair of damaged factory coatings; wrapping of irregular fittings (elbows, tees, flanges)

• Performance advantage: Conforms to irregularities without wrinkling; self-heals minor mechanical damage; no primer required on most mill-applied coatings (test first)

• Efficiency & cost advantage: Installation speed 2.5 m² per man-hour vs. 1.2 m² for heat-shrink sleeves; zero fuel/LPG cost; no hot work permit delays

4. Competitive Advantages

• Quality consistency: Batch-tested for peel adhesion (≥5 N/cm at 23°C) and dielectric strength; each roll QR-coded to certificate of analysis

• Supply reliability: Three redundant manufacturing sites (Asia, MENA, Europe); 98% on-time-in-full track record over 18 months

• Logistics capability: Direct container loading from port warehouses in Houston, Rotterdam, Shanghai, Jebel Ali

• Price competitiveness: Volume pricing 12–18% below 3M, Polyken, or Denso equivalent grades

• Sustainability: 100% solvent-free manufacturing; HDPE backing recyclable as class 2 plastic; no volatile organic compounds (VOCs)

• Technical support: Free site application audits, adhesion test kits, and NACE-certified corrosion engineer remote advisory

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 5 MT (approx. 680 rolls of 1.5 mm × 150 mm × 10 m)

• Bulk order threshold: 20 MT qualifies for tier-2 pricing (additional 9% discount)

• Loading capacity per 20 ft container: 22 MT (pallets double-stacked, interleaved with edge protectors)
  For 40 ft HC container: 26 MT maximum due to axle weight limits
