Products Description
PU Steel Wire Duct Hose, also known as polyurethane steel wire ventilation hose, is a flexible ventilation pipe made of high-quality polyurethane (PU) as the pipe wall base material, embedded with a high-strength steel wire skeleton, and compounded by special processes. The product combines flexibility and structural stability, with a smooth, burr-free pipe wall, light weight, and easy bending, making it suitable for various complex installation scenarios. It is mainly used for the conveying of gases, dust, particles, and other media, as well as ventilation and exhaust, and is widely applied in many fields such as industrial production, commercial buildings, and environmental protection.
Product Advantages
Wear Resistance
PU Steel Wire Duct Hose is made of high-quality polyether-based polyurethane material, whose wear resistance is significantly superior to that of ordinary PVC hoses.
Anti-Collapse
PU Steel Wire Duct Hose is embedded with a high-tension galvanized or copper-plated steel wire skeleton, which is closely arranged in a spiral and boasts strong supporting force.
Low Wind Resistance
The inner wall of the pipe is smooth and burr-free, which greatly reduces air resistance and significantly improves ventilation and dust collection efficiency.

Application Scenarios
Industrial Dust Removal: Connect to pulse dust collectors for conveying wood/metal dust (recommended wall thickness ≥ 1.0mm).
Material Conveying: Negative pressure suction of grain/plastic particles/powder (the service life of the wear-resistant model is increased by 50%).
Ventilation and Exhaust: Welding workshop fume emission/commercial kitchen fume extraction (oil-proof model optional).
High-Temperature Environment: Hot air conveying for boiler rooms/drying equipment (the high-temperature resistant model can withstand up to +120℃).
Core Technology
Integral Molding Process
The steel wire and PU layer are extruded synchronously, eliminating the risk of detachment caused by glue bonding.
Dynamic Fatigue Test
100,000 cycles of reciprocating bending are simulated without steel wire breakage or coating peeling.
Air Tightness Test
Each pipe undergoes a pressure holding test at twice the working pressure.
Functional Features
Ventilation and Exhaust Function
The pipe cavity is unobstructed with low wind resistance, which can efficiently convey air and other gases and quickly improve the space environment.
01
Dust Conveying Function
The wear-resistant inner wall can withstand the scouring of various particles, is not easy to adhere to dust, and avoids pipe blockage.
02
Flexible Telescopic Function
It can be freely telescoped and bent, suitable for complex installation scenarios, requiring no additional elbow accessories, and easy to store and move.
03
Sealing and Leak-Proof Function
The pipe wall is seamlessly formed, and special joints can be matched at the interface, featuring excellent sealing performance with no air or dust leakage.
04
Anti-Corrosion Function
It is resistant to ultraviolet rays, ozone, acids, and alkalis, and can be used for a long time in harsh environments such as outdoors and chemical industries.
