High Output Heat Shrink Tape Production Line for Water Supply Pipe Joints

Developed by Qingdao Huashida Machinery with over 21 years of pipeline anti-corrosion equipment manufacturing experience, this high-output heat shrink sleeve machine is a complete cross-linked PE sleeve production line for water supply pipeline joint protection. It integrates PE film extrusion, electron beam radiation crosslinking, and precision hot melt adhesive coating into one continuous system.

The line mass-produces heat shrink tape and sleeves for field joint coating (FJC), girth weld sealing, and buried pipeline corrosion protection. Controlled by a PLC system with an ABB main motor, the line delivers stable output, energy savings, and easy operation. It is widely used by customers in the Middle East, Russia, Central Asia, and Africa.

This plastic extrusion machinery supports standard two-layer sleeves and upgraded three-layer fiberglass reinforced sleeves. It is available in 650mm, 750–800mm, and 1100–1200mm configurations and can be customized to your sleeve width and output requirements. Finished water pipeline joint sleeves cover municipal water supply pipes, oil and gas transmission pipelines, district heating pre-insulated pipes, and drainage pipelines.

The line produces radiation cross-linked PE pipe joint protection materials in line with international anti-corrosion standards.

Cross-linked PE heat shrink tapes, conventional sleeves, and clip-on sleeves. With >150N/cm peel strength (ASTM D1000), they provide stable waterproof sealing for water supply and gas pipeline girth welds.

Three-layer reinforced heat shrink sleeves and tapes with 15–20MPa tensile strength, strong impact resistance, and long-term aging resistance. They suit large-diameter trunk pipelines in high-salinity, desert, and cold-climate regions.

Sleeves from this production line offer stable shrinkage, strong bonding, and excellent waterproof anti-corrosion performance for pipe joint protection:

• Water Supply Pipeline Joint Protection: girth weld and field joint coating of 3LPE/2PE coated steel pipes in municipal water supply and long-distance water transmission projects.
• Oil and Gas Pipeline Girth Weld Protection: large-diameter transmission pipelines and seamless steel pipe field joints.
• District Heating Pipeline Sealing: joint anti-corrosion and thermal sealing for PU foam pre-insulated pipelines.
• Drainage and Sewage Pipeline Sealing: spiral corrugated pipes, steel-reinforced plastic pipes, and PVC-U sewage pipes.
• Pipeline Maintenance and Rehabilitation: gap sealing, damage repair, and joint renovation of buried pipelines.

This pipeline anticorrosion machinery uses a modular configuration of extrusion system, hot melt adhesive coating system, optional fiberglass upgrade device, and PLC intelligent control for continuous production.

• RS-800 PE Backing Extrusion Line: this PE film extrusion line delivers a stable 150–200kg/h output of high-purity LDPE/HDPE backing film, ensuring uniform film for sleeve production.
• TJ-700 Adhesive Coating Line: a field joint coating machine for automatic online hot melt adhesive coating (DuPont, Sumitomo, and Hanwha compatible), with secondary stretching and shaping. It produces a uniform adhesive layer and >150N/cm peel strength.
• Fiberglass Reinforced Upgrade Configuration: fiber unwinding, constant-temperature heating, and leveling equipment for three-layer reinforced sleeves.
• Auxiliary and Intelligent Control System: irradiation crosslinking device, circulating cooling system, precision haul-off unit, PLC electric control, 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 (≤20°C, 0.3MPa)
• Compressed Air: ~0.4m³/min, working pressure >0.5MPa

This heat shrink sleeve machine uses a mature three-step molding process, standardized for global pipeline field joint coating material production:

1. High-Precision Substrate Extrusion: high-purity PE raw material is plasticized and extruded into flat, uniform backing film on the PE film extrusion line.
2. Electron Beam Radiation Crosslinking: professional irradiation gives the film a shape memory effect, high tensile strength, excellent elongation, and aging resistance. This is the core technology of any cross-linked PE sleeve.
3. Online Hot Melt Adhesive Coating and Shaping: the cross-linked film is precisely stretched and compounded with imported hot melt adhesive. Finished sleeves meet ASTM D1000 and DIN 30672.

• High Output, Stable Quality: 150–200kg/h substrate output with PLC and ABB motor for unattended, continuous sleeve production.
• Built for Water Supply Pipe Joints: one pipeline anticorrosion machinery line serves water, gas, oil, heating, and drainage joint protection projects.
• Two Products on One Line: standard two-layer and fiberglass reinforced three-layer sleeves from the same plastic extrusion machinery, saving equipment investment.
• International Standard Performance: >150N/cm peel strength, ≥100N/cm shear strength, and ≤0.05% water absorption.
• Premium Adhesive Compatibility: works with world-class brand hot melt adhesive coating materials for long-term bonding on buried pipelines.
• Proven Technology: independent R&D, a national expert workstation, 9 senior engineers, and 389+ global project cases.

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

• Tensile Strength: 15–20MPa (ASTM D638)
• Elongation at Break: ≥350%
• Peel Strength: >150N/cm (ASTM D1000)
• Shear Strength: ≥100N/cm (DIN 30672)
• Adhesive Softening Point: 70–80°C (ASTM E28)
• Water Absorption Rate: ≤0.05% (ASTM D570)
