Difference between corrugated hose and hose

1,Different materials
Bellows are generally made of metal materials such as stainless steel, copper, iron, etc. There are also some special bellows made of plastic materials. While the hose is mainly made of rubber or plastic and other elastic materials. As can be seen, the material difference between bellows and hose is large, but also determines their response to different media when the performance of the characteristics of the differences.

2,The structure is different
The structure of the bellows is more special, is composed of a series of wavy "folds", so it can be expanded and contracted, more suitable for turning and need to expand and contract the occasion. The structure of the hose is usually composed of an internal pipe layer, a reinforcement layer and an external protective layer, the internal pipe layer is usually made of rubber, polyurethane and other elastic materials, the reinforcement layer is usually made of steel wire braid, and the external protective layer is made of a corrosion-resistant material.

3,The application of different
There are also differences in the application scenarios of corrugated hose and hoses. Bellows are usually used in medical instruments, food processing, petrochemical and other occasions that require expansion and contraction; while the hose is usually used in industrial fluid transportation, fire equipment, automobile manufacturing and other occasions that require high pressure and heavy load. In addition, bellows are often used in high temperature and high pressure applications such as gases and vapors, while hoses are more suitable for conveying various liquid media.

This article compares the differences between bellows and hoses in terms of material, structure and application. According to the different characteristics of the two, we can choose different piping products to meet specific conveying needs according to the actual demand.
