3LPE Radiation Cross Linked Pipeline Protection Wrap Around HDPE Heat Shrinkable Sleeve for Weld Girth

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Pipeline Weld Protection: Designed to safeguard weld girth joints in pipelines from high-temperature exposure and corrosive environments through heat-shrinkable HDPE/PE material.
  • Dual Insulation: Provides both thermal insulation for extreme temperatures and electrical insulation (rated up to 10kV), making it suitable for power transmission and industrial applications.

Key features

  • 1. Radiation-Cross-Linked HDPE Material Technology

    • With radiation-cross-linked HDPE and PE material, ensure corrosion resistance and withstand temperatures up to 120°C. Compared to traditional non-cross-linked materials, this design offers ~30% longer service life in corrosive environments.

  • 2. High Voltage & Temperature Performance

    • Rated for 10kV voltage and extreme thermal stability, safely insulate electrical and thermal stress in industrial systems. Outperforms standard sleeves with lower voltage ratings in high-power applications.

  • 3. Customizable Scenario Solutions

    • Adjustable thickness, width, and length to fit diverse pipeline systems—from small-scale repairs to large industrial projects. Adapts to complex weld joints where rigid solutions fall short.

  • 4. Compliance with Safety Standards

    • Meets industry safety certifications for electrical insulation and environmental resistance. Ensures reliability in harsh environments where compliance is critical.

  • 5. Wrap-Around Design Efficiency

    • Quickly and securely install around weld girths with a pre-shaped wrap design. Reduces downtime compared to multi-step sealing methods requiring manual adjustments.

Supplier's note

  1. Key Technical Breakthroughs:

    • Radiation Cross-Linking: Enhances thermal stability and mechanical strength compared to traditional PE materials.
    • HDPE Material Blend: Offers 30% higher chemical resistance than standard PE sleeves.
    • Adaptive Shrink Ratio: The Pro Model’s 4:1 ratio ensures tight, gap-free sealing on irregular surfaces.

  2. Version Selection Guide:

    • Base Model: Suitable for standard pipelines (e.g., municipal utilities) operating below 100°C.
    • Advanced Model: Ideal for chemical plants or offshore systems requiring corrosion resistance and 120°C endurance.
    • Pro Model: Designed for high-temperature oil/gas applications (up to 150°C) and high-voltage transmission lines. Its triple corrosion resistance enables safe handling of aggressive chemicals like sulfuric acid. Pair its 4:1 shrink ratio with rugged HDPE to create a seamless, pressure-resistant seal.

*Compared to industry benchmarks, the Pro Model exceeds ISO 1817:2018 thermal stability standards by 25%.
