The Polyurethane (PU) Plastic-Reinforced Spiral Corrugated Hose is a high-performance, multi-purpose tubing engineered to meet the rigorous demands of industrial, commercial, and agricultural operations. Its core structure combines a smooth, wear-resistant PU inner wall with an integrated plastic spiral reinforcement (or optional copper-plated steel wire for static dissipation), delivering an unrivaled balance of flexibility, strength, and durability.
First, its material composition ensures exceptional longevity: the PU tubing (polyester-based) boasts a Shore A hardness of 95±2, providing superior resistance to abrasion, tearing, and impact—outperforming rubber or PVC alternatives by 3–5 times in high-wear scenarios (e.g., transferring granular materials like cement or grain). The plastic spiral reinforcement eliminates the need for heavy metal wires (unless specified) while maintaining structural integrity, enabling the hose to withstand positive pressures up to 10 bar and negative pressures (suction) of -0.9 bar, making it suitable for both delivery and vacuum-based material handling.
Second, it offers broad environmental adaptability: operating reliably in temperatures ranging from -40°C to 90°C (with short-term tolerance up to 120°C), it remains flexible even in extreme cold (unlike rigid PVC hoses) and resists deformation in high-heat environments. Additionally, the food-grade version (compliant with EU 10/2011 and FDA standards) is free of phthalates, BPA, and heavy metals, making it safe for transferring edible liquids (juices, wine, dairy) or dry food ingredients—critical for food processing and beverage manufacturing. For industrial use, it exhibits excellent chemical resistance to oils, mild acids, alkalis, and solvents, avoiding degradation in harsh working conditions.
Third, its user-centric design enhances operational efficiency: the ultra-smooth inner wall (Ra < 0.5 μm) minimizes friction loss, ensuring unobstructed flow of liquids, powders, or gases while preventing residue buildup (simplifying cleaning and reducing maintenance costs). The lightweight construction (≈30% lighter than rubber hoses of the same diameter) and kink-resistant spiral structure allow easy maneuvering, bending, and coiling—ideal for tight spaces (e.g., machinery ventilation, ship engine compartments) or mobile applications (e.g., agricultural sprayers, construction site pumps). Customizable sizes (inner diameter: 25mm–300mm; wall thickness: 0.6mm–2mm) and color options (transparent, black, or custom) further adapt to specific needs, from small-scale laboratory fluid transfer to large-volume mining slurry transport.
Finally, its versatility spans industries: in agriculture, it serves as irrigation lines or pump suction/discharge hoses; in manufacturing, it functions as ventilation ducts for textile machines or dust collection pipes for metal polishing equipment; in food processing, it transfers ingredients between production stages; and in mining, it handles abrasive ore particles. Optional static-dissipative versions (with grounded steel wire reinforcement, resistance < 10² ohm/m) add safety for flammable material transfer, reducing the risk of electrostatic discharge.
In summary, this hose merges rugged performance, hygiene compliance, and operational flexibility—making it a cost-effective, long-lasting solution for diverse material handling challenges
