What are the characteristics of the material of metal hoses?

The joints at both ends of the metal hose mainly include threaded connection, flange connection, and quick connector connection. The three main functions of the metal hose are to reduce the installation stress of the pipeline, compensate for the rated position movement of the pipeline, and absorb the vibration of the pipeline system.

Stainless steel mesh sleeve is the main pressure bearing component for installing metal braided hoses in pressure pipelines, while also providing protection for the metal hoses. Depending on the pressure in the pipeline and the application location, one or more layers of stainless steel wire or steel strip can be selected. It is woven according to certain parameters to form high-pressure metal hoses. The pressure range of our company's metal braided hoses is generally PN0.6-32.0MPa, with a maximum of 42.0MPa. There are mainly two types of stainless steel mesh sleeves: steel wire mesh sleeves and steel mesh sleeves.

Characteristics of corrugated metal hoses:

1. Recommended maximum allowable expansion per wave: full height type △ α= ± 24mm half height type △ α= ± 12mm.

2. Dust deflector: It is not necessary to use dust deflectors for air ducts or low dust pipelines, but dust deflectors should be used for high dust ducts.

3. To reduce the number of nodes in corrugated pipes, cold drawing should be considered by 50%.

4. The standard half height corrugated metal hose is suitable for situations where the cross-sectional area is less than 4.6 square meters and one side of the smoke and air duct has dimensions smaller than 1.5m but larger than 0.6mm. The standard full height corrugated metal hose is suitable for all smoke and air ducts.

Corrugated metal hoses have many characteristics such as good flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance, etc. They have a much longer lifespan compared to other hoses (rubber, plastic hoses), so they also have high comprehensive economic benefits. With the development of modern industry, the demand for corrugated hoses that are resistant to high temperature and pressure is also increasing.

Scope of application of hoses: Flexible conveying pipes are required to prevent vibration and are suitable for piping in areas such as steam, gas, air, heavy oil, petroleum, chemical drugs, etc.
