Although metal hoses are compressible and stretchable, they can quickly break and reduce their lifespan if not installed in the correct position.
Hoses can be installed horizontally, vertically, or at an angle. Ideally, they should be mounted vertically, and it's best to avoid placing them near wheels. A guard can be added if necessary.
Metal hoses can generally be categorized into three lengths: 1) Compressed Length, which is the length when the hose is compressed to its maximum position; 2) Installation Length, the length of the hose at the midpoint of the displacement; 3) Stretched Length, the length when the hose is stretched to its limit.
During installation, the hose should be positioned in the middle, known as the installation length. In this installed state, the hose can move in two directions when subjected to axial load. Otherwise, if it can only move in one direction, it will affect the strength of the metal hose and reduce its service life.
During the actual installation process, to avoid impacting production efficiency by measuring the hose length with a ruler based on calculated results before installation, some foreign manufacturers have opted to attach the ruler directly to the hose, and then cut it off after installation.
When selecting metal hoses, for ease of installation, please opt for metal hoses with one end featuring a loose-fitting flange.
During electrical welding operations on construction sites, protect the surface of metal hoses to prevent slag and arc striking from burning the metal hoses.
Do not twist the installation of metal hoses.
4. Do not bend at the base of the metal flexible hose, and avoid any sharp bends.
The medium must not be corrosive to the bellows material, and the chloride ion content in the medium should be ≤25 PPM.
6. Install strictly according to the illustrated correct installation method (see Installation Guide).
Do not allow any mechanical damage to the flange sealing surface.
