Sandblast hose is widely used in the various tunnels and hydropower. It is also used in mining industry. So it is called mining sandblast hose. It is mainly used for slag delivery, so it is required excellent abrasion resistance. Mining sandblast hose has the same structure with tunnel sandblast hose and hydropower sandblast hose. It is also composed of three parts: tube, reinforcement and cover. Tube is made from the mixture of polyurethane and butyl rubber, adding special reinforcing agent, making the hose highly resistant to abrasion and high pressure. And the hose has very good tenacity. Reinforcement is made from multiple layers of high tensile steel wires or high quality rubber cloth, making hose have solid structure and resistant to high pressure. Cover is made from natural rubber or neoprene, making hose resistant to oil, abrasion, corrosion, weather, ozone, heat, chemicals and aging. Therefore, mining sandblast hose is becoming more and more popular in mining industry.

Mining sandblast hose has high tensile steel wire reinforcement, making it bear high working pressure.
The details of mining sandblast hose:

Structure: it is composed of three parts: tube, reinforcement and cover.
Tube: the mixture of polyurethane and butyl rubber, adding special reinforcing agent, making the hose highly resistant to abrasion.
Reinforcement: multiple layers of high tensile braided steel wires or rubber cloth, making the hose have solid structure and resistant to high pressure.
Cover: natural rubber or neoprene, making the hose resistant to abrasion, corrosion, weather, ozone and aging.
Working temperature: -25 °F to +180 °F.
Working pressure: 10 bar (150 psi).
ID nominal size: 20 ± 0.75, 22 ± 0.75, 25 ± 0.75, 31.5 ± 1.25, 40 ± 1.25, 45 ± 1.50, 50 ± 1.50, 64 ± 1.50.
