Metal hose is one of the most important pipes in modern industry. However, there are many types of metal hose. While this time, let me introduce you corrugated hose.
Corrugated structure
Corrugated metal hose is characterized by its unique corrugated structure. This structure can effectively disperse the stress under the action of external force and improve the bending resistance. In addition, the corrugated structure also gives the metal hose excellent impact resistance. It has a long service life in complex environments.
Metal layer
The metal layer of corrugated metal hose is mainly made of stainless steel, carbon steel, etc. It has high strength and corrosion resistance to ensure its stable performance. The special processing technology gives the metal hose excellent ductility and elasticity. Therefore it can meet diverse engineering needs.
Lining layer
The lining layer is mainly used to prevent the medium inside the metal hose from coming into direct contact with the metal layer. Thereby reducing the corrosive effect of the medium. The inner lining material is generally non-metallic materials such as PE and PP. Has good corrosion resistance and friction properties.
Sealed structure
The sealing structure of corrugated metal hose is divided into nozzle sealing and sealing between bellows. The pipe mouth seal adopts metal flange, threaded connection and other methods to ensure stable connection and sealing performance. The seal between bellows is specially designed to achieve the sealing performance of the metal hose during expansion and contraction.
Materials and application scenarios of corrugated metal hoses
The materials of corrugated metal hoses mainly include stainless steel, carbon steel, alloy steel, etc.
Stainless steel metal hose has excellent corrosion resistance and is suitable for medium transportation in chemical, pharmaceutical and other industries.
Carbon steel metal hoses have high strength and are suitable for force transmission in construction, engineering and other fields.
Alloy steel metal hoses have good wear resistance and are suitable for the transportation of high-pressure media such as oil and natural gas.
