Why Our Hose Floats Stand Out
Abrasion Resistant Skin
3mm-thick polyurethane outer layer with Shore 75A hardness resists cuts, scrapes, and UV damage while remaining flexible - lasts 5X longer than PVC alternatives.
Integrated Safety Features
Glow-in-the-dark markers (8-hour phosphorescence) and retro-reflective strips provide 24/7 visibility, meeting IMO SOLAS visibility requirements.
Chemical Compatibility
Resistant to oils, acids (pH 1-13), and hydrocarbons (tested per ASTM D543) - making them suitable for petrochemical transfer applications.
Precision Buoyancy Control
Each float includes adjustable ballast chambers (+/- 15% buoyancy modification) for perfect neutral buoyancy tuning in different fluid densities.
Applications
► Mining slurry transport
► Construction site dewatering
► Industrial wastewater management

FAQ
1. What’s the expected service life?
10+ years with proper maintenance, backed by a 5-year warranty against material defects.
2. Can I get custom branding?
Yes – we offer laser engraving, color matching (RAL/Pantone), and logo molding (MOQ: 500 units).
3. Do you provide buoyancy calculations?
Our engineers provide CFD-supported buoyancy reports based on hose weight, fluid density, and environmental factors.
4. What’s your lead time for bulk orders?
2–3 weeks for standard stock, 4–5 weeks for custom configurations (10,000+ unit capacity/month).
