Metal hoses are flexible piping made of metal, typically made from materials like carbon steel and stainless steel. They are capable of bending and rotating, thus widely used in various industrial and commercial piping applications.

1. Structure: Metal hoses are typically composed of two main parts, the metal sheath and the inner tube. The sheath is made of carbon steel or stainless steel, offering high-temperature resistance, corrosion protection, and pressure resistance. The inner tube is woven from stainless steel mesh, with higher density resulting in better flexibility, vibration reduction, and a longer service life.

2. Types: Metal hoses come in various types, such as: bellows, vacuum hoses, and fan coil connectors. The bellows type is particularly common, characterized by its ability to withstand high pressure and high temperature, as well as its high flexibility and bendability, ensuring the normal operation of the pipeline.

Metal hoses can be installed by placing them parallel to the pipe and then tightening the threads. Do not use excessive force with a wrench to prevent the threads from slipping, which may affect the normal use of the pipe.
