Product Description
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 exclusively developed for sealing and anti-corrosion protection of district heating pre-insulated pipe joints, chilled water distribution pipeline joints, and PU foam insulated pipeline girth weld connections - the standard field joint coating solution for buried pre-insulated pipe systems worldwide.
This pre-insulated pipe joint heat shrink sleeve adopts premium two-layer composite construction: radiation cross-linked polyethylene backing (tensile strength 19.47MPa, elongation 626%) matched with high-adhesion imported hot melt adhesive (peel strength 145.6N/cm to steel) - together forming an integrated, seamless protective barrier that maintains the thermal insulation integrity and anti-corrosion performance of every pre-insulated pipe girth weld joint to the same standard as the factory-manufactured pipe sections.
For complete long-term underground protection, this radiation cross-linked PE heat shrink sleeve must be used with a supporting non-solvent two-component epoxy primer - together forming a continuous, gap-free anti-corrosion and waterproofing system at every district heating pre-insulated pipe girth weld connection, eliminating the primary failure point of buried pre-insulated pipeline networks.
Available in three configurable supply styles with thickness options from 1.2mm to 2.5mm and widths from 100mm to 900mm - covering all pre-insulated pipe, district heating, and municipal pipeline girth weld joint protection specifications.
Key Characteristics
Purpose-Built for Pre-Insulated Pipe Girth Weld Joint Sealing
Specifically engineered for the unique demands of pre-insulated pipe girth weld joints - where the sleeve must simultaneously seal against groundwater ingress, maintain polyurethane foam thermal insulation integrity, and provide long-term anti-corrosion protection to the exposed steel carrier pipe at every joint connection.
Fast & Simple On-Site Pre-Insulated Pipe Joint Installation
Supports easy heating-only on-site installation - no special tools, no surface grinding, no complex equipment required. When heated by standard propane torch, the radiation cross-linked PE outer layer shrinks uniformly around the pre-insulated pipe joint diameter while the inner hot melt adhesive melts evenly.
Factory-Grade Pre-Insulated Pipe Joint Protection Standard
Combining this radiation cross-linked PE heat shrink sleeve with non-solvent two-component epoxy primer creates a continuous, solid, gap-free protective barrier at every pre-insulated pipe girth weld joint - maintaining the same thermal insulation and anti-corrosion performance standard as the factory-manufactured district heating pre-insulated pipe sections.
Core Product Benefits
  • Pre-Insulated Pipe Girth Weld Waterproofing: Permanently seals district heating and chilled water pre-insulated pipe joints against groundwater ingress
  • Outstanding Chemical Anti-Corrosion Resistance: Effectively resists erosion from 10% HCl, NaOH, NaCl, and all harsh underground chemical media
  • Extreme Temperature Range Performance: Vicat softening point ≥90°C; brittleness temperature <-65°C - reliably serving buried district heating pre-insulated pipe joint protection
  • Superior Electrical Insulation: Dielectric strength ≥25MV/m; volume resistivity ≥1*10¹³Ω.m - maintaining full cathodic protection system compatibility
  • Long-Term Thermal Aging Resistance: After 150°C * 168h thermal aging - tensile strength retention ≥14MPa, elongation retention ≥300%
  • Universal Pre-Insulated Pipe Joint Solution: Compatible with black and yellow jacket HDPE pre-insulated pipes, PU foam insulated steel pipes, and all standard district heating pipeline girth weld joint connection configurations

Applications
  • District Heating Pre-Insulated Pipe Girth Weld Joint Sealing - seals every pre-insulated pipe girth weld connection against groundwater ingress and thermal insulation degradation
  • Chilled Water Pre-Insulated Pipe Joint Protection - seals chilled water distribution pre-insulated pipe joints where temperature differential creates persistent condensation risk
  • Petroleum Products Transmission Steel Pipe Field Joint Coating - provides factory 3LPE equivalent anti-corrosion protection at every pipeline girth weld joint
  • 3LPE/2LPE Anti-Corrosion Coated Steel Pipe Weld Joint Repair - restores full anti-corrosion system integrity at field joints and coating damage points
  • Municipal Drainage Corrugated Pipe Joint Anti-Corrosion Wrapping - provides waterproof and anti-corrosion joint protection for various sewage pipes
