Sandblast hose is used for various tunnels construction, such as well lane, cavern and slope spray anchor. It is also used for rust removal in ship building industry. This is the so-called ship building sandblast hose. It is used to remove the rust on the surface of ship by spraying sand to the ship, making ship have longer service life. It is highly resistant to abrasion, so it is becoming more and more popular in this industry. It is composed of three parts: tube, reinforcement and cover. And its structure is the same as tunnel sandblast hose. Tube is made from the mixture of polyurethane and butyl rubber, adding special reinforcing agent, making the hose resistant to abrasion and high pressure. Reinforcement is made from multiple layers of high tensile steel wires or high quality rubber cloth, making the hose have solid structure and bear high working pressure. Cover is made from natural rubber or neoprene, making the hose resistant to abrasion, corrosion, weather, ozone, aging, heat and chemicals.
