Radiation Cross-Linked PE Heat Shrink Sleeve for Oil Gas Pipeline Joint coating

Our high-performance cross-linked PE heat shrink sleeve is a professional pipeline field joint coating material exclusively developed for oil & gas transmission pipeline girth weld joint anti-corrosion protection. Widely recognized as the standard 3LPE field joint repair coating for buried pipelines worldwide, this pipe joint heat shrink sleeve adopts premium two-layer composite construction.

The construction features 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). For complete long-term underground anti-corrosion protection, this PE heat shrinkable sleeve must be used with a supporting non-solvent two-component epoxy primer - together forming an integrated, seamless anti-corrosion system equal to factory 3LPE pipe coating standard at every pipeline field joint.

Available in three configurable supply styles to match different pipeline construction demands, with thickness options from 1.2mm to 2.5mm and widths from 100mm to 900mm - covering all oil & gas, district heating, and municipal pipeline field joint coating specifications.

The imported hot melt adhesive inside this cross-linked PE heat shrink sleeve delivers ultra-high peel strength - 145.6N/cm to steel, 205.9N/cm to epoxy primer, 190.0N/cm to PE layer (all tested per ASTM D1000) - far exceeding the ≥70N/cm minimum requirement. This ultra-strong bonding performance achieves stable, tight adhesion between the cross-linked PE backing, bare steel pipe surface, and epoxy primer base coat - eliminating hollow gaps, peeling, and water penetration at pipeline girth weld joints.

This pipe joint anti-corrosion heat shrink sleeve 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 while the inner hot melt adhesive melts evenly - fully wrapping all steel pipe joint diameters in one heat application, significantly cutting field joint coating labor hours.

Combining this radiation cross-linked PE heat shrink sleeve with non-solvent two-component epoxy primer creates a continuous, solid, gap-free anti-corrosion barrier at every pipeline girth weld field joint. Long-term anti-corrosion performance fully matches standard factory 3LPE steel pipe coating - solving the weakest link in buried pipeline anti-corrosion.

• Outstanding Chemical Anti-Corrosion Resistance: Effectively resists erosion from 10% HCl, NaOH, NaCl, and all harsh underground chemical media - tensile retention ≥85% after 7-day chemical immersion (ASTM D638)
• Extreme Temperature Range Performance: Vicat softening point ≥90°C (tested 92°C); brittleness temperature <-65°C - reliably serving buried pipeline field joint coating in extreme cold regions through high-temperature service conditions
• Superior Electrical Insulation: Dielectric strength ≥25MV/m (tested 33.13MV/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 (tested 20.7MPa), elongation retention ≥300% (tested 630%)
• All-Round Mechanical & Weather Durability: Cross-linked PE structure delivers waterproof, wear-resistant, impact-resistant, UV-resistant, and anti-aging performance
• Universal On-Site Pipeline Joint Solution: Compatible with all major buried pipeline types - reducing field joint construction cost and time

This cross-linked PE heat shrink sleeve is purpose-built for oil & gas pipeline girth weld connection, buried pipeline field joint coating (FJC), pipe wrapping, anti-corrosion protection of all pipeline joint types, and on-site damage repair.

• Oil & Gas Transmission Steel Pipe Field Joint Coating - provides factory 3LPE equivalent anti-corrosion protection at every pipeline girth weld joint
• PU Pre-Insulated Thermal Insulation Pipe Joint Sealing - seals district heating pre-insulated pipe joints against groundwater ingress
• 3LPE/2LPE Anti-Corrosion Coated Steel Pipe Weld Joint Repair - restores full anti-corrosion system integrity at field joints
• Municipal Drainage Corrugated Pipe Joint Anti-Corrosion Wrapping - provides waterproof and anti-corrosion joint protection

We supply three configurable styles of cross-linked PE heat shrink sleeve to match different oil & gas pipeline field joint coating construction demands:

• Pre-cut heat shrink sleeve with separate closure patch - standard configuration for most oil & gas pipeline field joint applications
• Pre-cut heat shrink sleeve with pre-attached integrated closure patch - streamlined single-component installation for faster field joint coating
• Continuous heat shrink sleeve roll tape (closure patch ordered separately) - for high-volume pipeline field joint coating projects requiring customized cut lengths on site

Available Specifications:

• Thickness: 1.2mm, 1.6mm, 1.8mm, 2.0mm, 2.5mm
• Width: 100mm, 200mm, 300mm, 500mm, 600mm, 900mm
• Roll length: 30m or 50m per roll
• Custom dimensions available on request
