Overview
This high-performance TPU drag hose is manufactured using a three-layer composite structure and a one-step co-extrusion process, specifically engineered for demanding applications including agricultural irrigation, slurry/manure transfer, and industrial fluid conveyance. The hose delivers exceptional abrasion resistance, puncture resistance, delamination resistance, and chemical resistance, ensuring long-term, maintenance-free service even in the harshest operating conditions.

Exceptional Adhesion Strength & Superior Fatigue Resistance:
The hose features a three-layer composite structure:
① TPU Liner (Inner Layer)
The liner is extruded from high-quality thermoplastic polyurethane (TPU) using a through-the-weave extrusion process, forming a continuous, smooth inner wall. The TPU liner offers outstanding chemical resistance against manure, fertilizers, oils, and various industrial fluids, ensuring no medium contamination during transfer while minimizing flow resistance for maximum conveying efficiency
② Reinforcement Layer (Middle Layer)
The middle layer consists of a high-strength woven fabric made of polyester fiber or aramid. This woven reinforcement provides excellent pressure resistance, tensile strength, and dimensional stability, maintaining hose integrity during towing operations and withstanding both tractor traction forces and pumping pressures.
③ TPU Cover (Outer Layer)
The outer cover is co-extruded from TPU material and tightly bonded with the reinforcement layer. The TPU cover delivers superior abrasion resistance, protecting against ground friction, stone impact, and sharp object puncture. It also features excellent resistance to UV radiation, hydrolysis, and aging, ensuring long-term outdoor durability.

Key Features
 Exceptional adhesion strength: The liner and cover are co-extruded with the reinforcement layer in a single process, delivering high peel strength and eliminating delamination risks.
Superior abrasion & puncture resistance: TPU material withstands continuous ground friction and impact during towing operations.
Excellent chemical resistance: Resists manure, fertilizers, acids, alkalis, and a wide range of chemicals.
Outstanding fatigue resistance: Maintains stable performance under repeated bending, coiling, and dragging conditions.
Lightweight & flexible: Easy to coil, store, transport, and deploy in the field.
Diameter stability: Maintains consistent inner diameter over long-term service, ensuring stable high-volume flow capacity.

Applications
Towed agricultural irrigation: Ideal for tractor-towed hose systems covering large-scale field irrigation.
Agricultural slurry/manure transfer: Suitable for pumping treated livestock manure through drag hoses, covering several kilometers for precision fertilization, enabling efficient waste-to-resource recycling.
Industrial fluid transfer: Applicable for mine dewatering, municipal emergency water supply, and industrial wastewater conveyance.
Installation & Coupling
The hose is compatible with various quick-connect couplings for easy installation:
Agricultural quick couplings: Specially designed for drag hose applications, enabling fast connections without special tools.
German-style large-diameter couplings: Suitable for high-volume transfer applications, providing secure and reliable connections.
   Installation process: Insert the hose end into the coupling and secure with a closure ring or clamp. The lightweight design allows single-person deployment and retrieval.
