Flexible Metal Tubing

Metal hose is an important component in the connection pipeline of modern industrial equipment.

  • Details

Metal hose is an important component in the connection pipeline of modern industrial equipment. Metal hose used for wire, cable, automatic meter signal wire cable protection pipe and civil shower hose, specifications from 3mm to 150mm. Small diameter metal hose (inside diameter: 3mm-25mm) is mainly used for precision optical ruler sensing line protection and industrial sensor line protection.

The principle of:

Pipeline installation stress

In complex pipeline system, the limitation of space position condition often occurs, which causes various difficulties in installation work. Bending over, coming forward, fitting the tube into place will inevitably result in local cold correction. Depending on the size of the pipe and the specific conditions on the site, the cold calibration ranges from a few millimeters to tens of millimeters, some up to hundreds of millimeters. The practice shows that the greater the amount, the higher the internal stress will be, and the residual installation stress in the pipeline system is undoubtedly the maximum hidden stress.

A section of bearing lubricating oil pipe in a certain type of engine has been broken several times in actual operation, which is caused by excessive installation stress.

Due to bending and under the condition of nominal bending radius of bending stresses in the tiny, so that it can bring great convenience to installation work, safe operation of pipeline system also plays a certain role. This is the main reason why some piping systems have to use metal hoses.

Compensating pipe position

The moving cylinder of the vulcanizer will move up and down due to the need of loading and unloading the mould. After repeated reciprocation, the copper snake-shaped pipe will suffer from fatigue fracture. Although it can still be used after repair, the parking repair will cause time loss. Rubber hose, although has a good soft features, anti-fatigue ability is very strong, but in terms of pressure, heat resistance, anti-aging and weak links, and the use of a few months later, general was no longer able to continue. The good comprehensive performance of metal hose is fully reflected here. In general industrial field, in addition to pressure, temperature, and often there are some, such as fatigue, corrosion, vibration, pressure, impact and other harsh conditions, under such circumstances, to compensate the pipe position is the most appropriate.

Absorption of vibration

In a large building, air conditioning in the hall is provided by a 6FWB unit fixed in the basement. The vibration of the unit is transmitted to the ground hall by connecting the bridge with the pipeline, and the noise value is up to 45dB. In such an environment, people always feel a sense of discomfort. After improving design, on the connecting pipe string the metal hose, not only absorbed the parts produced by the vibration noise, the noise produced by fluid pulsation in the piping also absorbed a lot, at this point, the ground hall is only 33 db noise values, greatly improved the environment of the hall.

It can absorb vibration, it can not only improve the system fatigue damage ability, but also reduce the noise effect. This is why metal hoses are used in some piping systems.

The characteristics of

Due to the hose materials of main parts are made by austenitic stainless steel, thus ensure the good temperature resistance and corrosion resistance of the hose, hose a wide working temperature range, to - 196-196 ℃, the use of hose according to pipeline medium grade choose suitable stainless steel corrosion, to ensure that the corrosion resistance of the hose.

1. The metal hose is made of 1Cr18Ni9Ti stainless steel material and has strong corrosion resistance.

2. Hose body for the thin-wall stainless steel tube hydroforming, has strong flexibility, scalability, bending and strong ability of anti vibration, weaving nets to strengthen protection, make it has higher bearing capacity.

3. The connection between the two ends of the hose can also be made into other connection modes other than screw thread and flange standard for convenient connection and use.

4. This product is not only suitable for supporting rotating joint, but also widely used for soft connection of various fluid medium. Resistance to corrosion, high temperature resistant, low temperature (196 ℃ ~ + 420 ℃), light weight, small volume, good flexibility. Widely used in aviation, aerospace, petroleum, chemical industry, metallurgy, electric power, papermaking, timber, textile, construction, medicine, food, tobacco, transportation and other industries.

1. Flexible hose between metal hose pitch and small bending radius.

2. The metal hose has good scalability, no blocking or stiffness.

3. The metal hose is light in weight and has a good consistency in caliber.

4. Flexible metal hose, repeated bending and good flexibility.

5. Metal hose corrosion resistance, high temperature resistance.

6. The metal hose is anti-rat bite and good wear resistance, preventing the internal wire from being worn.

7. Metal hose bending resistance, tensile performance, strong side pressure resistance.

8. The metal hose is soft, smooth and easy to be installed and positioned.

9. The metal hose is equipped with many hose joints, which is easy to connect with the equipment.
