Metal hoses are hoses made of metal strips rolled into a curved cross-sectional shape and have high flexibility and elasticity. Metal hoses have properties such as compression resistance, tensile strength, torsion resistance, vibration resistance, and high temperature resistance, and are widely used in transportation pipeline systems in industries such as chemical, petroleum, mining, ships, and aviation. Metal hoses are usually composed of inner tubes, corrugated layers, protective layers, and joints. Different usage environments require the use of different materials and structural forms of metal hoses.
