Product Description

Radiation Cross-Linked PE Heat Shrink Sleeve for 3LPE Pipeline Field Joint Repair

Product Overview

Radiation Cross-Linked PE Heat Shrink Sleeve for Pre-Insulated Pipe Girth Weld Joint

Our high-performance radiation cross-linked PE heat shrink sleeve is a professional pre-insulated pipe girth weld joint protection material, specially developed for sealing and anti-corrosion of district heating pre-insulated pipe joints, chilled water distribution pipeline joints and PU foam insulated steel pipe girth weld connections.

As mainstream field joint coating material for buried pre-insulated pipeline projects widely used in Russia, Central Asia and Middle-East markets, this heat shrink sleeve solves joint water-ingress risks for underground heating networks.

Adopting premium two-layer composite structure: radiation cross-linked polyethylene backing (tensile strength 19.47 MPa, elongation 626%) compounded with high-adhesion imported hot-melt adhesive (peel strength 145.6N/cm to steel). It forms a seamless integrated protective barrier, keeping the same thermal-insulation and anti-corrosion performance as factory-produced pre-insulated pipe sections.

Key Characteristics

Purpose-Built for Pre-Insulated Pipe Girth Weld Joint Sealing - Engineered for harsh working conditions, blocks groundwater infiltration, preserves PU foam thermal-insulation integrity and delivers durable anti-corrosion for exposed carrier steel pipe at pipeline joints.
Fast & Simple On-Site Pre-Insulated Pipe Joint Installation - User-friendly torch-heating only field installation, no complicated special equipment or heavy surface grinding required.
Factory-Equivalent Pre-Insulated Pipe Joint Protection Standard - Matched with non-solvent two-component epoxy primer, builds solid gap-free protective enclosure for every girth-weld joint.

Core Product Benefits

Pre-Insulated Pipe Girth Weld Waterproofing

Reliably seals district-heating and chilled-water pre-insulated pipe girth-weld joints against underground water intrusion.

Excellent Chemical Anti-Corrosion Resistance

Resists erosion from 10% HCl, NaOH, NaCl and various complex underground corrosive media.

Wide Extreme-Temperature Adaptability

Vicat softening point ≥90°C; brittleness temperature <-65°C. Performs steadily in high-temperature and frigid cold-climate regions.

Superior Electrical Insulation Property

Dielectric strength ≥25MV/m; volume resistivity ≥1×10¹³Ω*m. Fully compatible with cathodic-protection systems.

Long-Term Thermal-Ageing Resistance

Maintains stable physical property under long-term buried district-heating pipeline service.

Wide Compatibility

Fits black & yellow HDPE jacket pre-insulated pipes, PU-foam insulated steel pipes, and all mainstream district-heating pipeline girth-weld joint connection forms.

Applications

District-Heating Pre-Insulated Pipe Girth-Weld Joint Sealing - Primary application for buried district-heating networks
Chilled-Water Pre-Insulated Pipe Joint Protection - For condensation-prone working conditions
Petroleum-Product Transmission Steel-Pipe Field-Joint Coating - Delivers 3LPE-equivalent anti-corrosion protection
3LPE / 2LPE Anti-Corrosion Coated Steel-Pipe Weld-Joint Repair - Restores complete anti-corrosion system
Municipal Drainage Corrugated-Pipe Joint Anti-Corrosion Wrapping - Provides waterproof and anti-corrosion joint protection

Application Scenarios

Field joint coating of steel pipe with 3LPE coating

Sealing pre-insulated pipe

Connecting and sealing drain pipes
