Corrugated metal hose structure and characteristics

Corrugated metal hose (hose for short) is a high-quality flexible pipe in modern industrial pipelines. It is mainly composed of bellows, mesh sleeves and joints. Its inner tube is a thin-walled stainless steel corrugated tube with a spiral or annular waveform, and the mesh sleeve on the outer layer of the corrugated tube is woven from stainless steel wire or steel strip according to certain parameters. The fittings or flanges at both ends of the hose are matched to the fittings or flanges of the customer's pipeline.

The bellows of the hose is formed by high-precision plastic processing of extremely thin-walled seamless or longitudinally welded stainless steel pipes. Due to the elastic characteristics of the contour of the bellows, the hose has good flexibility and fatigue resistance, making it easy to absorb various motion deformations and cyclic loads, especially in the pipeline system. It has the ability to compensate for large displacements.

The mesh sleeve is the main pressure-bearing part of the hose installed in the pressure pipeline, and it also acts as a sheath for the bellows. According to the pressure in the pipeline and the application place, one or more layers of stainless steel wire or steel belt can be selected for Weaving, the pressure range of Shuguang brand hose is generally PN0.6-32.0Mpa. Up to 42.0MPa.






Since the main parts of the hose are made of austenitic stainless steel, the excellent temperature resistance and corrosion resistance of the hose are guaranteed. The working temperature range of the hose is very wide, ranging from -196 to 600 degrees. The corrosion resistance of the hose can be guaranteed by selecting the appropriate stainless steel grade according to the corrosiveness of the medium passing through the pipeline.

Corrugated metal hose has many characteristics such as good flexibility, fatigue resistance, high pressure resistance, high and low temperature resistance, corrosion resistance, etc. Compared with other hoses (rubber, plastic hose), its life is much longer, so It also has higher comprehensive economic benefits. With the development of modern industry, the demand for corrugated metal hoses with high temperature resistance and high pressure resistance is also increasing.

Scope of application of the hose: The conveying pipe needs to be fully flexible, and the piping in the place to prevent vibration is suitable for steam, gas, air, heavy oil, petroleum, chemical drugs, etc.
