Radiation Cross-Linked PE Heat Shrink Sleeve Line for Pipeline Girth Weld Protection

Developed by Qingdao Huashida Machinery with 21+ years of pipeline anti-corrosion equipment manufacturing experience, this 1100-1200mm radiation cross-linked PE heat shrink sleeve production line (Model 1350) is the largest-width fully automatic intelligent manufacturing system in our heat shrink sleeve equipment series.

Specially built for large-diameter pipeline girth weld protection and field joint coating (FJC), this turnkey extrusion line integrates professional PE substrate extrusion, electron beam irradiation crosslinking and precision hot melt adhesive lamination technology to mass-produce high-performance pipeline anti-corrosion sleeves and tapes.

Widely deployed in Middle East, Russia, Central Asia and African oil & gas municipal infrastructure projects, it delivers one-stop manufacturing solutions for buried steel pipeline field joint anti-corrosion engineering.

This fully automatic heat shrink sleeve manufacturing line supports diversified customized mass production, outputting high-standard radiation cross-linked PE protective materials for pipeline girth weld joints, fully compliant with international anti-corrosion norms:

Finished radiation cross-linked PE heat shrink sleeves boast stable shrinkage performance, ultra-strong bonding force and excellent waterproof anti-corrosion capability, widely applicable to multiple pipeline engineering fields worldwide:

• Oil & Gas Pipeline Girth Weld Protection: Ideal for long-distance large-diameter oil gas transmission pipelines, 2PE/3LPE anti-corrosion steel pipe girth weld joints and seamless steel pipe field joint coating
• District Heating Pipeline Sealing: Professional joint anti-corrosion and thermal sealing for PU foam pre-insulated pipelines
• Municipal & Industrial Drainage Pipeline Protection: Compatible with large-diameter spiral corrugated pipes, steel-reinforced plastic pipes and PVC-U sewage pipes
• Pipeline On-Site Maintenance & Rehabilitation: Perfect for gap sealing, damage repair and field joint renovation of buried pipelines

This complete 1100-1200mm Model 1350 heat shrink sleeve production line adopts modular integrated configuration - consisting of core extrusion system, adhesive coating system, fiberglass reinforced upgrade device, and PLC intelligent control system - realizing fully automated continuous oil gas girth weld protection material production:

• Working Place: Indoor non-hazardous production workshop
• Power Supply: 380V 50HZ (-10%, +5%)
• Working Humidity: ≤85%, no condensation
• Circulating Cooling Water: ~0.5m³/min (≤20ºC, 0.3Mpa)
• Compressed Air: ~0.4m³/min, working pressure >0.5Mpa

Standard Three-Step Oil Gas Girth Weld Protection Material Forming Process:

The line adopts a mature three-step integrated molding process, standardized for global pipeline field joint coating material production, with stable process parameters and consistent finished product quality:

Three-Layer Fiberglass Reinforced Process:

Based on the standard three-step process, automatic fiberglass unwinding, constant-temperature heating, and precise leveling procedures are added - realizing one-time continuous forming of three-layer fiberglass reinforced heat shrink sleeves in 1100-1200mm width.

• Ultra-Wide 1100-1200mm Production Range: The widest specification in Huashida's sleeve line series, exclusively for extra-large-diameter pipeline girth weld anti-corrosion projects
• Multi-Functional One-Machine Design: Single equipment produces both standard two-layer sleeves and fiberglass reinforced three-layer sleeves
• International Standard Performance: Finished sleeves feature >150N/cm peel strength, ≥100N/cm shear strength and ultra-low water absorption rate (≤0.05%)
• Intelligent & Energy-Saving Operation: PLC + ABB motor full automatic control realizes unattended continuous production
• Premium Adhesive Compatibility: Adaptable to world-class brand hot melt adhesives
• Patented Mature Technology: Independent R&D one-pass molding technology with global verified project cases

All finished radiation cross-linked PE heat shrink sleeves strictly comply with ASTM, DIN and GB/T international industry standards:
