►Purpose:
To discharge solid or liquid materials such as mineral sand, coal shavings, and mud at room temperature, mainly used in various tunnels engineering, well rolls, caverns, slope protection and anchoring are widely used in fields such as hydropower and mining.
►Operating temperature:
- 20℃~+45℃
►Structure:
The inner rubber layer is made of synthetic rubber such as butadiene rubber, natural rubber, styrene butadiene rubber, carbon black, etc., and the middle layer.
For synthetic fabrics or curtain layers, the outer rubber layer is made of synthetic rubber such as natural rubber, styrene butadiene rubber, carbon black, etc.
Triple protection, durable upgrade
Super wear-resistant, doubling the lifespan
Inner rubber layer: Made of high hardness and wear-resistant rubber (Shore hardness ≥ 75A), reinforced with diamond microbeads, the wear resistance index reaches 120 mg (ISO 4649 standard), which is more than three times that of ordinary rubber hoses.
Pressure resistant and explosion resistant, safe and reliable
Enhancement layer: Adopting double-layer high-strength polyester fiber weaving and spiral steel wire skeleton, with a working pressure of ≥ 8Bar and a burst pressure of ≥ 24Bar, far exceeding the industry standard (GB/T 1186-2007).
Weather resistant and corrosion-resistant, suitable for all scenarios
Outer rubber layer: chloroprene rubber (CR)+anti-aging additives, ozone resistant, UV resistant, outdoor service life of more than 5 years. Chemical resistance: acid and alkali resistant, compatible with various sandblasting media such as steel sand, copper ore sand, glass beads, etc.
Problem and solution of this product
Ship rust removal and sandblasting
- Corrosion from seawater outdoor exposure, rubber hoses are prone to aging
Anti corrosion outer layer+weather resistant formula, suitable for high humidity and high salt environments
Cleaning of mining equipment

Thickened pipe wall+impact resistant structure, capable of withstanding high-frequency and high-strength sandblasting
Steel structure anti-corrosion sandblasting
- Long homework time (≥ 8 hours per day), requiring pressure resistance
Double layered reinforced layer design, no deformation or leakage under continuous high pressure
Concrete surface treatment
- Large dust and high temperature (60-80 ℃)
High temperature resistant rubber+heat dissipation structure, suitable for high temperature working environment
