750-800mm Radiation Cross-Linked Polyethylene Heat Shrink Metal Reinforced Tape

Backed by more than 20 years of hands-on expertise in industrial machinery manufacturing, Qingdao Huashida Machinery Co., Ltd. has engineered a high-performance, energy-efficient heat shrinkable tape and sleeve production line — a fully integrated intelligent system built exclusively for the production of top-tier pipeline anti-corrosion and joint sealing materials. Engineered with state-of-the-art extrusion technology, electron irradiation crosslinking processing, and continuous online lamination techniques, this versatile production line supports the manufacturing of both standard two-layer heat shrinkable products and enhanced three-layer fiberglass-reinforced heat shrinkable tape and sleeves. Engineered for durability and reliability, these finished products serve as a trusted solution for joint corrosion protection, on-site pipeline repair, and secure sealing across municipal pipeline networks, oil and gas transmission systems, and a wide range of industrial pipeline applications. Boasting low energy consumption, minimal operational noise, stepless speed adjustment capabilities, and a fully automated operating system, this production line sets a high benchmark for technical performance and finished product quality in both domestic and global industrial markets.

• Standard Products: 650mm width, Two-layer PE heat shrinkable tape, sleeve-type heat shrinkable sleeves, clip-on heat shrinkable sleeves
• Upgraded Products: Three-layer fiberglass reinforced PE heat shrinkable tape/sleeve

This production line’s finished anti-corrosion and sealing products are engineered to fit a comprehensive range of pipeline varieties, including hollow wall spiral winding pipes, steel-reinforced spiral corrugated tubes, plastic-steel composite spiral winding pipes, double flat wall plastic-steel spiral tubes, unplasticized polyvinyl chloride (PVC-U) sewer pipes, polyurethane foam pre-insulated pipes (black and yellow outer jacket pipes), 3PE/2PE coated steel pipes, seamless steel pipes, large-caliber wastewater discharge pipes, and other conventional steel pipeline options.
