Functions of Flexible Metal hoses


Our company(Shandong Hesper Rubber Plastic, Co., Ltd.) produce and supply flexible metal hoses(belong to our metal hoses). We have stainless steel metal hoses, PVC or silicone coated metal hoses, food grade flexible metal hoses, PTFE/Teflon lined metal hoses, also can customize according to customers’ requests. Flexible metal hoses have following functions:

     1.Reducing installation stress on pipes.

In a complex piping system, often has difficulties during installation due to the limitation of space and location conditions: the formed pipe cannot be installed; the pipe which is bent, straightened and installed, will inevitably cause partial cold correction. Depending on the diameter of the pipe and the specific conditions of the site, the amount of cold correction ranges from a few millimeters to several tens of millimeters, and some reach hundreds of millimeters. Practice has proved that the larger the amount, the higher the internal stress. The installation stress remaining in the pipeline system is undoubtedly a great hidden danger.

Since metal hoses can be bent at will and the internal stress generated by bending under the condition of rated bending radius is extremely small, it can bring great convenience to the installation work, and also plays a certain role in the safe operation of the pipeline system. This is the main reason why some piping systems must use flexible metal hoses.


2.Compensating pipe position shift

Although rubber hose has good soft properties and strong anti-fatigue ability, it  weak in terms of pressure bearing, temperature resistance, and anti-aging. Generally, it cannot continue used after several months of use. The good comprehensive performance of the metal hose is fully reflected here.

In the general industrial field, in addition to pressure and temperature, there is often harsh conditions such as fatigue, corrosion, vibration, compression, impact, etc. In such cases, metal hoses are used to compensate for the position movement of the pipeline is the most appropriate.

3.Absorbing piping system’s vibration.

 metal hoses which be connected in series in the connecting pipelines can not only absorb part of the noise which generated by the vibration of the unit, but also absorb the noise which generated by the fluid pulsation in the piping system, which greatly improves the environment in the house. Metal hoses can absorb vibration, not only can improve the ability to anti-fatigue damage, but also can reducing noise.
