Metal hoses are an essential component in the piping connections of modern industrial equipment. They are used as protective conduits for electrical wires, cables, and signals of automation instruments, as well as civil shower hoses, with sizes ranging from 3mm to 150mm. Ultra-small diameter stainless steel hoses (inner diameter 3mm-25mm) are primarily used for protecting the sensor lines of precision optical scales and industrial sensors, offering excellent flexibility, corrosion resistance, high-temperature resistance, wear resistance, and tensile strength.
