The role of flexible metal hose

We know that a flexible metal hose is an important component of modern industrial equipment connecting pipelines. So what is the working principle of the flexible metal hose? What is the function of flexible metal hose in different situations?

Here is the content list:

Installation stress of flexible metal hose pipe

In the complex flexible metal hose system, flexible metal hose often has various difficulties in the installation of flexible metal hose due to the limitation of space and location conditions: the formed flexible metal hose can not be installed.The flexible metal hose will inevitably produce a local cold correction. Depending on the diameter of the flexible metal hose and the specific conditions of the site, the cold correction amount of the flexible metal hose ranges from a few millimeters to tens of millimeters, and some up to hundreds of millimeters. The practice has proved that the greater the amount, the higher the internal stress, and these remaining installation stresses in the flexible metal hose pipeline system are undoubtedly extremely hidden.

In a certain type of engine, a section of the bearing lubricating oil conduit has broken the flexible metal hose many times in actual operation, which is caused by the excessively high installation stress of the flexible metal hose.

Since the flexible metal hose can be bent at will and the internal stress generated by bending under the rated bending radius is very small, the flexible metal hose can bring great convenience to the installation work and also contribute to the safe operation of the flexible metal hose pipeline system. Play a certain safeguard role. This is the main reason why flexible metal hose must be used in certain flexible metal hose piping systems.

 

Compensation pipeline position

Due to the need of loading and unloading flexible metal hose molds, the movable cylinder on the vulcanizing machine will move upward and downward. After the copper snake-shaped flexible metal hose reciprocates many times, the flexible metal hose will be fatigued and broken. Although the flexible metal hose can continue to be used after the repair, the parking repair will cause time loss. Although rubber flexible metal hose has good soft characteristics and strong anti-fatigue ability, it is a weak link in terms of pressure resistance, temperature resistance, and aging resistance. Generally, it cannot continue after a few months of use.The good comprehensive performance of the flexible metal hose is fully embodied here. In general industrial fields, in addition to pressure and temperature, flexible metal hoses often have anti-fatigue, anti-corrosion, and anti-vibration properties.

 

Absorb vibration

In a huge building with a flexible metal hose, the air-conditioning flexible metal hose in the hall is provided by a 6FWB unit fixed in the basement. The vibration of the unit is transmitted to the ground hall through the bridge connecting the flexible metal hose pipe, and the noise value reaches 45dB. In an environment like a flexible metal hose, people always feel that a flexible metal hose has a sense of discomfort. After improving the design, the flexible metal hose is connected in series to the connecting pipe, which not only absorbs part of the noise generated by the vibration of the unit but also absorbs a lot of the noise generated by the fluid pulsation. At this time, the ground noise value in the hall is only 33dB.

Able to absorb vibration, the flexible metal hose can not only improve the fatigue damage ability of the system, but the flexible metal hose can also achieve the effect of reducing noise. Some piping systems use the flexible metal hose for this reason.
