The technical parameters of PU hose include the following aspects:
Temperature range: PU hose has a wide operating temperature range, usually between -40℃ and +90℃, and can withstand a high temperature of +125℃ for a short time. In addition, PU steel wire hose can withstand a wider temperature range, from -35℃ to 120℃.
Pressure range: The working pressure range of PU hose is 0.5～1 Mpa, and the maximum working pressure can reach 1.9～3 Mpa.
Corrosion resistance: PU hose has good corrosion resistance and can resist the erosion of mineral oils, animal and plant oils, dilute acids and concentrated acids. In addition, it can also resist the erosion of solvents such as gasoline, aromatics, esters, ethers, and alcohols.
Physical properties: The hardness range of PU hose is 50A-75D, with good elasticity, friction resistance and water absorption resistance. It has high transparency and the flow state of the medium is clearly visible.
Application fields: PU hoses are widely used in the fields of industry, agriculture, food, medicine, civil engineering, fishery, aquaculture, garden irrigation, etc., for conveying fluids with general working pressure, such as pneumatic pipes, hydraulic pipes, garden hoses, oil and water pipelines, etc. In addition, PU steel wire hoses are also commonly used in ventilation, exhaust and dust collection, as well as mechanical equipment such as automobiles, motorcycles, and construction machinery.
