Metal hose: Metal hose is an important part in the connecting pipeline of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, automatic instrument signals and civil shower hoses, with specifications ranging from 3mm to150 mm. Small-caliber metal hose (3mm-25mm in inner diameter) is mainly used for sensor circuit protection of precision optical ruler and industrial sensor circuit protection.
Flexible metal sleeve: flexible (metal) conductor protection sleeve (now called flexible metal conduit). The foundation KZ is made of external hot-dip galvanized steel strip wrapped around a special insulating resin layer on the inner wall. Waterproof KV is coated with soft PVC on the basis of the basic model, and flame retardant KVZ is coated with soft flame retardant PVC on the basis of the basic model.
Ultra-small diameter metal wire protective sleeve (inner diameter 3mm-25mm) is mainly used for sensor circuit protection of precision optical ruler and industrial sensor circuit protection, with good flexibility, corrosion resistance, high temperature resistance, wear resistance and tensile resistance.
2. Different applications
Metal hose: used to protect various equipment signal wires, transmission wires and cables, and optical cables. Wire protection tubes for armored optical cables, precision optical rulers, optical measuring instruments, medical instruments and mechanical equipment; Suitable for public telephones, remote water meters, door magnetic alarms and other equipment that need to protect wires safely;
Protective tubes for various small wires; Network line protection tubes for various computers, robots, etc. PVC external protective film for solar energy equipment.
Flexible metal sleeve: used as wire and cable protection tube for wires, cables and automatic instrument signals, with specifications ranging from 3mm to130 mm.
3. Different characteristics
Metal hose: corrosion resistance, high temperature resistance, low temperature resistance (-196℃~+420℃), light weight, small volume and good flexibility. Widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electric power, paper making, wood, textile, construction, medicine, food, tobacco, transportation and other industries.
Flexible metal casing: this kind of pipe is relatively light, only one-third of steel pipe, so it is listed as an energy-saving and material-saving environmental protection project by the Ministry of Energy of the State Planning Commission.
Excellent corrosion resistance, due to the adoption of hot dip galvanized steel strip technology, its corrosion resistance is incomparable with steel pipe and metal hose.
The shielding performance is good, and the test results show that it is the same as that of steel pipe.
The length is not limited, and it can be cut at will according to the needs of the project, reducing the consumption of odd parts.
There are threads and various corresponding accessories on the surface of the pipe. Bending does not require a machine. As long as the special cutting tool is used on site, it is very convenient to cut, and 40%-90% of working hours can be saved in construction and decoration applications. In the shipbuilding industry, it can improve the work efficiency by 6 times.
Pipe has good strength and insulation, can be embedded in reinforced concrete net, and can be shaped as needed to make up for the weakness of steel pipe, metal hose and PVC pipe in some occasions.
