High-pressure hose is a kind of pipe used to transport fluids, gases or chemicals. Because of its special material and structural design, the high-pressure hose can withstand the working environment under high pressure to ensure the safe transportation of fluid. High-pressure hose is a kind of flexible pipeline that can withstand high pressure and is widely used in industrial production and life. Its main features include smooth appearance, small bending radius, excellent oil resistance, heat resistance and aging resistance, etc. High pressure hose has good oil resistance, heat resistance and aging resistance, high pressure resistance and excellent pulse performance. High-pressure hoses are divided into fiber-reinforced polyurethane hoses, fiber-reinforced nylon hoses, steel wire-reinforced polyurethane hoses, steel wire-reinforced nylon hoses, steel wire-wound resin hoses and food-grade hoses. High-pressure hose generally consists of inner tube, reinforcing layer and outer tube. The inner tube is usually made of corrosion-resistant and high-temperature resistant materials to ensure the purity and chemical stability of the transported fluid. The reinforcing layer is made of high-strength fiber material or wire mesh to increase the pressure resistance of the hose, while the outer tube is used to protect the inner tube and the reinforcing layer and prolong the service life of the hose.
