Automatic Hot Melt Adhesive Coating Machine for Heat Shrink Sleeve with Reactor

Product Description

Cross-Linked PE Heat Shrink Sleeve Production line for Pipeline Field Joint Protection

Product Overview

Developed by Qingdao Huashida Machinery with 21+ years of pipeline anti-corrosion equipment manufacturing experience, this TJ-700 hot melt coating line is a fully automatic adhesive coating machine for heat shrink sleeve and tape production. It is built for 1100-1200mm wide PE back film coating and is the core stage of our cross-linked sleeve equipment. It combines a 300L reactor, a PE backing stretching unit, an adhesive coating roller and a PLC control system to mass-produce high-performance pipeline anticorrosion sleeves for girth weld and field joint coating (FJC). It is widely used by customers in the Middle East, Russia, Central Asia and Africa.

This heat shrink sleeve machine works as a standalone coating line or alongside our RS-800 PE backing extrusion line. It supports standard two-layer sleeves and, with an added upgrade kit, three-layer fiberglass reinforced sleeves, so one sleeve making machine covers both product types. It complements our 650mm and 750-800mm models and covers the full size range for oil and gas transmission pipelines, district heating pre-insulated pipelines and municipal drainage pipelines.

Finished Products

This adhesive coating machine supports customized mass production of radiation cross-linked PE protective materials for pipeline girth weld joints, in line with international anti-corrosion standards.

Standard Two-Layer Products: 1100-1200mm cross-linked PE heat shrink tapes, conventional sleeves and clip-on sleeves. With >150N/cm peel strength (ASTM D1000), they give stable anti-corrosion sealing for buried oil and gas pipeline girth welds and municipal field joint coating.

Upgraded Fiberglass Reinforced Products: three-layer reinforced heat shrink sleeves and tapes with 15-20MPa tensile strength, strong impact resistance and long-term aging resistance. Made on a fiber reinforced sleeve line, they suit large-diameter trunk pipelines in high-salinity, desert and cold-climate regions.

Sleeves made on this heat shrink tape coating line have stable shrinkage, strong bonding and excellent waterproof anti-corrosion performance:

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

Core Production Process

This hot melt coating line is the third step of a three-step molding process used worldwide for pipeline field joint coating materials:

Step 1, Substrate Extrusion: high-purity PE is extruded into flat, uniform back film on the RS-800 line.
Step 2, Electron Beam Radiation Crosslinking: professional irradiation gives the PE film a shape memory effect, high tensile strength and aging resistance. This is the core technology of any cross-linked sleeve equipment.
Step 3, Online Adhesive Lamination and Shaping: the cross-linked film is precisely stretched and compounded with imported hot melt adhesive from the 300L reactor. The finished sleeves meet ASTM D1000 and DIN 30672.

Three-Layer Fiberglass Reinforced Process: automatic fiberglass unwinding, constant-temperature heating and precise leveling are added to the standard process. This forms three-layer reinforced sleeves in one continuous pass, with ≥100N/cm shear strength (DIN 30672) and more stable shrinkage.

Automatic Hot Melt Adhesive Coating Machine for Heat Shrink Sleeve with Reactor

One Coating Machine, Two Products: the same adhesive coating machine makes standard two-layer and fiberglass reinforced three-layer sleeves, saving equipment investment.
Ultra-Wide 1100-1200mm Range: the widest in our sleeve line series, covering extra-large-diameter girth weld projects.
International Standard Performance: >150N/cm peel strength, ≥100N/cm shear strength and ≤0.05% water absorption.
Intelligent and Energy-Saving: PLC and ABB motor give automatic, continuous operation with lower labor and energy costs.
Premium Adhesive Compatibility: works with world-class brand hot melt adhesives for long-term bonding on buried pipeline joints.
Proven Technology: independent R&D, a national expert workstation, 9 senior engineers and 389+ global project cases.
