In the actual installation process, considering that it may affect the production efficiency to use a ruler to measure the length of the hose according to the calculation result before installation, some foreign manufacturers install rulers directly on the hose and cut off the ruler after installation. The metal hose can be installed horizontally, vertically or diagonally, ideally vertically, and should not be installed near the wheels. Baffles can be added if necessary.
Generally, the metal hose can be divided into three lengths: the first is the compression length, that is, the length of the hose compressed to the limit position; The second is the installation length, which is the length of the hose in the middle of half of the maximum displacement. The third is the stretch length, the length when the hose is stretched to its maximum limit. Metal hose installation should be in the middle of the hose, that is, the so-called installation length. Under the installation condition at this position, the hose can move in two directions when it is subjected to axial load, otherwise, it can only move in one direction, which will affect the strength of the metal hose and reduce its service life.
