1100-1200mm Cross-Linked PE Heat Shrink Sleeve Production Line for Oil Gas Girth Weld

Developed and manufactured by Qingdao Huashida Machinery Co., Ltd. - a professional manufacturer with 21+ years of experience in pipeline girth weld protection equipment and plastic extrusion machinery - this 1100-1200mm cross-linked PE heat shrink sleeve production line (Model 1350) is the largest-configuration fully automatic intelligent manufacturing system in the Huashida heat shrink sleeve product family.

This production line integrates advanced PE substrate extrusion technology, professional electron beam irradiation crosslinking process, and precise online hot melt adhesive lamination coating technology to produce high-performance large-diameter pipeline girth weld joint anti-corrosion heat shrink sleeves and tapes.

This 1100-1200mm cross-linked PE heat shrink sleeve machine (Model 1350) supports diversified product customization and mass production:

• Standard Products: 1100-1200mm width two-layer cross-linked PE heat shrinkable tape, conventional sleeve-type heat shrinkable sleeves, and clip-on heat shrinkable sleeves meeting ASTM D1000 peel strength >150N/cm standard
• Upgraded Products: High-strength three-layer fiberglass reinforced PE heat shrinkable tape and sleeves with enhanced tensile resistance (15-20MPa), impact resistance, and aging resistance for ultra-harsh underground conditions

• Oil Gas Pipeline Girth Weld Protection: Primary application for 1100-1200mm width sleeves covering long-distance large-diameter oil and gas transmission pipelines
• District Heating Pipeline Joint Sealing: Purpose-built for joint sealing and anti-corrosion of large-diameter polyurethane (PU) foam pre-insulated pipelines
• Municipal & Drainage Pipeline Protection: Compatible with large-diameter hollow wall spiral wound pipes, steel-reinforced spiral corrugated pipes, and PVC-U sewage pipes
• On-Site Maintenance & Repair: Ideal for on-site damage repair, gap sealing, and field joint coating of large-diameter buried pipelines

• RS-800 PE Backing Extrusion Line: Stable output of 150-200kg/h for high-purity LDPE/HDPE substrate extrusion
• TJ-700 Adhesive Coating Line: Automatic online hot melt adhesive coating with >150N/cm peel strength
• Fiberglass Reinforced Upgrade Configuration: Supports production of high-strength three-layer fiberglass reinforced heat shrink sleeves
• Auxiliary & Intelligent Control System: Complete supporting equipment including PLC electric control system and ABB high-performance main motor

• 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

• Substrate Extrusion: High-purity LDPE or HDPE raw materials are plasticized and extruded to form uniform PE backing film at 150-200kg/h output
• Electron Beam Irradiation Crosslinking: PE backing film undergoes professional electron beam irradiation crosslinking treatment for stable thermal shape memory effect and excellent tensile strength (15-20MPa)
• Online Lamination & Shaping: Cross-linked PE film is precisely secondarily stretched and bonded with imported hot melt adhesive, achieving >150N/cm peel strength

Automatic fiberglass unwinding, constant-temperature heating, and precise leveling procedures are added to realize one-time continuous forming of three-layer fiberglass reinforced heat shrink sleeves with enhanced structural strength and pressure resistance.

• 1100-1200mm Large Width Configuration: The widest cross-linked PE heat shrink sleeve production line in the Huashida family
• High Efficiency & Energy Saving: Direct-connection single-screw extrusion technology with 150-200kg/h stable output
• PLC + ABB Motor Intelligent Control: Industry-trusted control system for adjustable production speed and fully automatic operation
• One-Machine Multi-Use: Produces both standard two-layer and high-strength three-layer fiberglass reinforced products
• Premium Adhesive Compatible: Imported hot melt adhesive from global top brands ensures >150N/cm peel strength
• Leading Patented Technology: Independent R&D three-layer one-pass molding technology at international advanced level

All finished 1100-1200mm radiation cross-linked heat shrink sleeves produced by this Model 1350 line fully comply with ASTM, DIN, and GB/T international standards:

• Tensile Strength: 15-20 MPa (Tested by ASTM D638)
