PRODUCT DESCRIPTION Structure: Consists of high pressure expansion hoses, middle steel pipe, sliding sealing coupling and pressure injection coupling. Application: Water injection at coal seam, gas suction and discharge. Technical Parameter: 1. Diameter: 60~150mm(can be customized) 2. Working pressure: 1~6Mpa(can be customized) 3. Operating speed of fluid: 5-8 tons per hour, the amount of gas depending on concentration and pressure. 4. Expansion index: 60~100% Functions: 1. Water injects into the coal seam and releases partial gas, effectively reduces the amount of gas at coal seam. 2. Once the effect of water injection is reached, it can reduce over 80% of dust power and improve working atmosphere, protect from dust explosion. 3. It can moist coal seam and protect coal from self-flaming. 4. Once the system of suction and discharge drilling hole is adopted, the amount of gas and drilling cuttings could be obviously increased, effectively releases gas pressu...

Steel Wire Reinforced Concrete Pump Hose Works Well in High Pressure Environment

图片
Steel wire reinforced concrete pump hose , also called steel wire reinforced concrete delivery hose, is widely used in concrete placement industry, such as bridge, large dams and port construction. The hose is composed of three parts: tube, reinforcement and cover. Tube is made from chloroprene rubber, making the hose can stand up to the highly abrasive concrete. Reinforcement is made from 2 or 4 layers of high tensile steel wires, which makes the steel wire reinforced concrete pump hose work well in the high pressure environment. Cover is made from chloroprene rubber, which is resistant to weather, ozone, corrosion and abrasion. Steel wire reinforced material handling hose is suitable for various concrete wet spraying machines, pumps and other pneumatic equipment of cement and mineral products delivery. It is highly resistant to abrasion, making it work well in extremely harsh working conditions. And its excellent abrasion resistance performance prolongs its service life. It has go...
