1, the definition of different
Metal hose: metal hose is a modern industrial equipment to connect the pipeline in the important components. Metal hose used as wires, cables, automated instrumentation signal wire and cable protection tube and civil shower hose, specifications from 3mm to 150mm. small diameter metal hose (inner diameter 3mm-25mm) is mainly used for precision optical ruler of the sensing line protection, industrial sensor line protection.
Flexible metal casing: flexible (metal) wire protection casing (now known as bendable metal conduit), the basic type KZ material for the outer layer of hot-dip galvanized steel tape wound into the inner wall of a special insulating resin layer, waterproof type KV in the basic type of the basis of the outer covering of soft polyvinyl chloride, flame-retardant KVZ in the basic type of the basic type of the outer covering of soft flame-retardant polyvinyl chloride.
Super small diameter metal wire protection sleeve (inner diameter 3mm-25mm) is mainly used for precision optical ruler sensing line protection, industrial sensor line protection, with good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile strength.
2, different applications
Metal hose: used as a variety of equipment signal lines, transmission wires and cables, fiber optic cable protection. Armored fiber optic cable, precision optical ruler, optical measuring instruments, medical instruments, machinery and equipment with wire protection tube; applicable to public telephones, remote water meters, door alarms and other magnetic need for wire safety protection equipment;
A variety of small wires of the protection of the tube; a variety of computers, robots and so on, the network line protection with the tube. PVC outer protective film for solar energy equipment.
Flexible metal casing: used as wires, cables, automated instrumentation signal wire and cable protection tube, specifications from 3mm to 130mm.
3, different characteristics
Metal Flexible Hose: corrosion-resistant, high-temperature, low temperature (-196 ℃ ~ +420 ℃), lightweight, small size, good flexibility. Widely used in aviation, aerospace, petroleum, chemical, metallurgy, electric power, paper, wood, textile, construction, medicine, food, tobacco, transportation and other industries.
Flexible metal casing: the light weight of the tube, only one-third of the weight of the 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.
Superior corrosion resistance, due to the use of hot-dip galvanized steel strip process, its corrosion resistance steel pipe and metal hose can not be compared.
Good shielding performance, test results show that it is the same as steel pipe.
The length is not limited, according to the needs of the project, any cutting, for this reason reduces the consumption of change.
The tube has a threaded appearance, with a corresponding variety of accessories, bending without machinery, cutting as long as the special cutter on-site construction, it is very convenient, in the construction and renovation applications can save 40% -90% of the labor time. In the shipbuilding industry can improve labor efficiency six times.
The pipe has good strength, good insulation, can be pre-buried in the reinforced concrete network: and can be customized to make up for the steel pipe and metal hose and PVC pipe in certain occasions the weakness of construction.
