Metal Hose Assembly It is mainly composed of three parts: a metal bellows, a mesh sleeve, and connectors. The metal bellows provides flexibility in the metal hose and is made of thin-walled stainless steel with a spiral or circular wave pattern. The plastic mesh is made by weaving iron wires or steel strips that overlap each other in a certain order. It is installed on the outer surface of the corrugated hose and has a reinforcing function. Connector types are generally divided into three categories: spiral, flange, and quick-connect.

　　I. Characteristics of Metal Hose Assemblies

　　1. Metal hoses are mainly made of stainless steel sheet, with high corrosion resistance.

　　2. Metal hoses have a wide operating temperature range, from -196 to 600℃, and good high-temperature stability.

　　3. The metal hose body is hydroformed, with excellent flexibility, good ductility, strong bending and shock resistance, and advantages such as bending resistance, compressive strength, and pressure resistance.

　　II. Installation and Application of Metal Hose Assemblies

　　Although metal hose assemblies have good flexibility and strong capabilities, pressure resistance and high-temperature resistance are weak points. Generally, after a few months of use, they can no longer continue. The good comprehensive performance of metal hoses is well reflected here. In general industrial applications, in addition to working pressure and ambient temperature, there are often harsh standards such as fatigue, corrosion, vibration, and impact. In such cases, using them to compensate for pipeline displacement is correct.

　　III. Appearance of Metal Hoses

　　The metal hose assembly's plastic mesh is corrosion-resistant, and the appearance is bright and beautiful. It can improve the load-bearing capacity and high and low-temperature test ability of the plastic hose products, extend the service life of the tube body, and reduce costs. Generally, metal hoses only use one layer of plastic mesh; in special places, there are two or three layers of weaving. According to the different size requirements of the metal bellows, wires with a diameter of 0.3-0.8 mm or amorphous strip materials with a thickness of 0.2-0.5 mm are generally used. Each strand has 4 to 15 wires, and each ingot has one amorphous strip material.

　　Metal hoses have good bending characteristics and a smooth internal structure, making them easy to use when threading wires and cables. Applicable to transportation lines, locomotives, urban transportation construction projects, household central air conditioning, various industrial equipment, automated machinery, power generation, chemical industry, power transmission and transformation engineering systems, communication systems, ships, business centers, and indoor and outdoor wiring maintenance in factories.
