As one of the important parts connecting various components in modern engineering technology, metal hoses are mainly used as wires, cables, wire and cable protection pipes for automatic instrument signals and civilian shower hoses, with specifications ranging from 3mm to 150mm. The smaller-caliber hose is mainly used for the protection of the sensing circuit of the precision optical ruler and the protection of the industrial sensor circuit. It is widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries.

However, in the actual use process, many metal hoses are ruptured or broken due to excessive pressure. Why? What is its withstand voltage range? Generally speaking, the pressure range of the hose is generally PN0.6-32.0Mpa; up to 42.0MPa. As the main pressure-bearing part installed in the pressure pipeline, the hose acts as a sheath for the bellows. According to the pressure in the pipeline and the application site, one or more layers of stainless steel wire or steel belt can be selected for braiding.
