The role of metal hose

Large metal hoses can be used in high-rise buildings for drainage, heating, and other piping systems, but nowadays applications in life are more common. A small layer of woven mesh is added to the outer surface of the mini-metal hose to make the performance better. , anti-corrosion, high temperature resistance, longer anti-oxidation life. Metal hoses are an important part of the modern industry. Wire and cable protection tubes and civil shower hoses for protection of wires, cables, and automation instrumentation, from 3mm to 150mm. Small-diameter metal hoses (inner diameter 3mm-25mm) are mainly used for sensing line protection of precision optical scales and industrial sensor line protection. The main role of metal hoses is as follows:

First, reduce the installation stress of the pipeline

In complex piping systems, there are often difficulties due to space position conditions, resulting in installation difficulties: the formed pipe can not be loaded; bending over, coming over, making up the installed pipe will inevitably produce local Cold correction. Depending on the pipe diameter and the specific conditions on site, the amount of cold correction ranges from a few millimeters to tens of millimeters, and some hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress, and the installation stress of these residues in the pipeline system is undoubtedly extremely invisible. In some models of the engine lubricating oil pipe, the fracture accident occurred many times in actual operation, because the installation stress is too high.

Since the metal hose can be bent at will and the internal stress generated by bending under the rated bending radius is extremely small, it can bring great convenience to the installation work and also guarantee the safe operation of the pipeline system. effect.

This is the main reason why some piping systems must use metal hoses.

Second, the compensation pipe position movement

Due to the need to load and unload the mold, the movable cylinder on the vulcanizer will move in the upward and downward directions. After the copper serpentine tube reciprocates many times, fatigue fracture occurs, although it can be used after repair, but the parking repair will cause time loss. Although the rubber tube has good softness and strong anti-fatigue ability, it is also a weak link in terms of pressure, temperature resistance and anti-aging. It can not be continued after several months of use. The good overall performance of the metal hose is fully reflected here.

In the general industrial field, in addition to pressure and temperature, there are often harsh conditions such as fatigue, corrosion, vibration, pressure, impact, etc. Under such circumstances, metal hoses are used to compensate for the positional movement of the pipe. It is the most appropriate.



Third, the vibration of the absorption pipeline system

The metal hose is connected in series on the connecting pipe, which not only absorbs the noise generated by the vibration of the unit, but also absorbs the noise generated by the fluid pulsation in the pipe system, which greatly improves the environment inside the house. The metal hose absorbs vibration, which not only improves the fatigue and damage of the system, but also reduces the noise. That's why the piping systems of some giant buildings use metal hoses.
