Industrial PVC Lay-Flat Hose Machine

The PVC lay flat hose production line is a dedicated equipment for manufacturing lightweight, collapsible water transport hoses. By integrating melt extrusion, flat die forming, and precision cooling, it produces hoses that can be rolled into compact coils (reducing storage volume by 70% compared to rigid pipes) for easy transportation and on-site deployment. The line adopts a modular design—allowing easy expansion or replacement of key components (e.g., extrusion die, rolling unit)—and is equipped with an automatic defect detection system (via visual cameras) to identify surface flaws, making it a core equipment in water-saving projects for its high production efficiency and excellent product flexibility.

Forming Technology: Specialized flat extrusion die (with precision machining of 0.02mm) ensures hose thickness uniformity (error ≤±0.1mm) and smooth inner wall. The die’s internal flow channel is optimized via CFD simulation to eliminate material dead zones, preventing black spots or bubbles in the final product. A non-stick Teflon coating on the die surface reduces material adhesion, cutting cleaning downtime by 50%.

Speed Control: Variable frequency drive system (with overload protection) adjusts production speed from 5m/min to 30m/min, matching different thickness requirements (0.3-2.0mm). The speed control system is synchronized with the downstream rolling unit to avoid hose stretching or wrinkling during processing.

Rolling System: Automatic torque control rolling machine with 500kg maximum roll weight and adjustable roll tightness. It supports continuous rolling without manual intervention, and the roll-changing mechanism enables quick coil replacement (≤5 minutes) to minimize production interruptions.

Material Compatibility: Compatible with PVC resin (including recycled PVC with up to 30% content), plasticizers, and anti-aging additives. The produced hoses exhibit 90%+ elongation at break and excellent folding resistance—withstanding over 10,000 folding cycles (180° fold) without cracking, making them ideal for repeated storage and deployment.

Applications

Agricultural Irrigation: Produces portable hoses for greenhouse drip irrigation and field flood irrigation, with flow rates up to 15m³/h (for φ100mm diameter hoses). The hoses are lightweight (≈0.8kg/m for standard thickness), allowing easy handling by a single worker and reducing labor costs for farmers.

Municipal Water Supply: Used to manufacture emergency water delivery hoses for pipeline maintenance (e.g., burst pipe repairs). The hoses are resistant to tap water corrosion (passing 5,000-hour immersion testing without degradation) and can be connected to standard pipe fittings via quick-connect couplings.

Disaster Relief: Critical for quick-deployment hoses in flood control and drought relief operations. The collapsible design enables transportation via small vehicles or even helicopters, and the hoses’ rapid connection feature (≤30 seconds per joint) ensures fast setup of temporary water supply lines.

FAQ

Q: Can this line produce food-grade water hoses?

A: Yes, by using food-grade PVC resin (meeting GB 4806.7 standards) and FDA-certified additives, the line can produce hoses meeting FDA 21 CFR 177.1950 standards. Additional post-production cleaning processes (using purified water rinsing) are available to remove residual additives, ensuring compliance with food contact requirements.

Q: What is the water pressure resistance of the produced hoses?

A: Standard products (without reinforcement) withstand 0.8-1.2MPa; high-pressure models (incorporating polyester fiber mesh layers) can reach 2.0MPa and are suitable for high-lift irrigation or long-distance water transmission. The pressure resistance is tested via 1.5x rated pressure static testing for 1 hour to ensure no leakage.
