The materials commonly used in high-pressure hydraulic hoses

High pressure hydraulic hose is one of the essential components of hydraulic system, its role is to transfer liquid and energy, connect hydraulic components and hydraulic system parts. The choice of high pressure hydraulic hose material has a crucial impact on the performance and safety of the hydraulic system. This article will introduce the materials commonly used in high-pressure hydraulic hoses.Synthetic rubber: Synthetic rubber is one of the most common high-pressure hydraulic hose materials, the main components are nitrile rubber, propylene rubber, neoprene rubber and butyl sulfide rubber. Synthetic rubber has good wear resistance, corrosion resistance and high temperature resistance, suitable for various industrial hydraulic systems. At the same time, the cost of synthetic rubber is relatively low, so it is also one of the main materials for hydraulic hoses.Polyester: Polyester is a polymer synthetic material that has good elasticity and wear resistance and is commonly used in high pressure hydraulic hoses with low to moderate pressure. The advantages of polyester materials are light weight and good flexibility, which can meet some occasions that require flexible hoses.Polyurethane: Polyurethane is a high strength, low weight material suitable for high pressure hydraulic systems and hydraulic systems of construction machinery. Polyurethane hose has excellent tensile and wear resistance, and its pressure resistance and dimensional stability are also very good.Wire braid layer: Wire braid layer is used to enhance the strength and pressure resistance of high-pressure hydraulic hoses, usually using high-strength steel wire as a material. The wire braided layer prevents the hose from bursting due to excessive pressure and maintains its shape when the hose is bent, increasing the hose's life and safety.In short, the material selection of high-pressure hydraulic hoses should be carried out according to the specific working conditions and use requirements. When selecting materials, it is necessary to consider factors such as working pressure, temperature, medium and environment, and choose the appropriate materials and structures according to actual needs. In order to ensure the safety and reliability of the hydraulic system, it is recommended to choose high-quality hydraulic hoses and products produced by professional manufacturers to avoid the use of inferior materials and processes, so as to reduce the risk and maintenance costs of the hydraulic system
