In the realm of pneumatic conveying, dust extraction, and ventilation systems, hose reliability directly determines operational continuity and workplace safety. Traditional rubber or PVC hoses often fall short when facing sharp particles, continuous flexing, or extreme temperature fluctuations. Our PU polyurethane steel wire reinforced hose (commonly known as PU steel wire hose or wire-reinforced vacuum hose) is engineered to overcome these limitations, delivering exceptional service life and performance in the most demanding material handling environments.

What Makes Our PU Steel Wire Hose Stand Out

At its core, this hose features a transparent or semi-transparent polyurethane (PU) wall embedded with a helical steel wire spring. This ingenious combination delivers a unique balance of properties that no single-material hose can match:

1. Exceptional Abrasion Resistance

Polyurethane is globally recognized as the material with the highest abrasion resistance among all elastomers. Our PU hose withstands the constant scouring of dry bulk materials such as cement, sand, granules, powders, and wood chips, offering a service life 5 to 10 times longer than standard rubber or PVC hoses. This dramatically reduces replacement frequency and lowers total ownership costs.

2. Crush-Proof and Kink-Proof Construction

The embedded steel wire spiral acts as an external skeleton, providing robust structural integrity. This design ensures the hose maintains its round cross-section under high vacuum pressure (up to -0.9 bar), preventing collapse or kinking that can interrupt material flow. Even during sharp bending, the steel wire reinforcement prevents wall flattening, ensuring consistent throughput.

3. Lightweight with Excellent Flexibility

Despite its robust construction, the PU steel wire hose remains surprisingly lightweight and flexible. This translates to easy handling, reduced operator fatigue during manual setup, and seamless integration into moving machinery arms or robotic systems.

4. Wide Temperature Range and Chemical Stability

Our PU compound retains its mechanical properties across a broad temperature range from -40°C to +90°C (with short-term peaks up to 120°C). It also offers good resistance to oils, greases, and many chemicals, making it suitable for diverse industrial environments.

Versatile Applications Across Industries
Our PU steel wire reinforced hose is the preferred conveying line in numerous industrial sectors:
Pneumatic Conveying Systems
Plastics Industry: Conveying virgin pellets, regrind, and compound materials from silos to injection molding machines or extruders.
Food & Pharmaceutical: Handling dry food powders, grains, sugar, and pharmaceutical intermediates (with food-grade PU options available).
Mining & Construction: Extracting dust, slurries, and fine aggregates in processing plants.
Dust Extraction and Ventilation
Woodworking: Collecting sawdust, wood chips, and sanding dust directly from machinery such as table saws, planers, and CNC routers.Metal Fabrication: Capturing grinding sparks, metal shavings, and welding fumes.
General Factory Ventilation: Serving as flexible ducting for fume extraction hoods and portable ventilation fans.Medium-Duty Material Handling
Agricultural grain loading and unloading.
Dry bulk tanker truck discharge.
Foam and insulation material blowing.
Product Specifications and Customization
Understanding that every application has unique requirements, we offer comprehensive customization options:

Parameter Options
Inner Diameter 25mm to 500mm (1" to 20")
Wall Thickness Standard 0.9mm, 1.2mm, 1.5mm, or custom
Steel Wire Pitch Standard or custom spacing for different vacuum ratings
Color Transparent, blue, orange, or custom (for easy content visibility)
Hardness Shore 85A to 95A
Certifications Standard industrial, food-grade (FDA-compliant), or flame-retardant (UL94 V-0)
Length Standard 10m, 15m, 20m, or cut to exact requirements
Superior Inner Surface for Unrestricted Flow
Unlike hoses with convoluted internal ridges, our PU steel wire hose features a smooth inner wall, which minimizes pressure drop and prevents material buildup. This is particularly critical when conveying sticky or moist materials, where internal fouling can otherwise cause blockages and cleaning downtime.

Built to Last: Quality Assurance
Every length of PU steel wire hose undergoes rigorous quality control, including:

Dimensional accuracy verification.

Burst pressure and vacuum testing.

Abrasion loss measurement per DIN 53516 standard.

Visual and dimensional inspection of steel wire embedment.

We ensure that each hose leaving our factory meets the highest standards of consistency and durability.

A Smart Investment for Your Material Handling Operations
Upgrading to PU polyurethane steel wire reinforced hoses is not merely a replacement choice – it is a strategic investment in your production efficiency and workplace safety. By reducing unplanned downtime due to hose failures, improving operator convenience, and extending replacement intervals, our hoses deliver rapid return on investment.
