9.1 FORWARD
Rubber hoses are designed taking into account their intended use.
The life of a hose is dependant on many factors which can affect its normal life. An improper use of the hose
may affect or even jeopardize the product safety and or cause damage to other people.
Therefore, the user is required to carry out preventive maintenance measures, also for his/her own interest,
in particular when high operating pressures and the use of aggressive media are involved. In any case, when
signs are detected which may indicate a reduced function of the hose, replace the hose or at least check it
appropriately.
These recommendations are a minimum level of action by the user and are to be considered as a suggestion
by IBIX.
9.2 Radius of curvature
Hose installations with hose radius smaller than the minimum radius of curvature greatly reduce the
hose life. Furthermore, it is necessary to prevent hose bends immediately after the hose fittings.
9.3 Torsion
Save as otherwise indicated, abrasive hoses are not designed to work when in torsion.
9.4 Traction
Tractive efforts must fall within the limits specified by the hose manufacturer. If you have any
doubts on the suitability of the abrasive hose when used in traction, contact the manufacturer
beforehand.
9.5 Bending
Some users are accustomed to interrupt the flow of media by bending the abrasive hose. This habit
is not recommended by hose manufacturers, because the hose reinforcement is submitted to specific
stress which may cause premature bursting.
9.6 Abrasive media
To achieve optimal operating life, abrasive hoses should be kept as straight as possible, except for
the strictly necessary bending areas. In case of such necessary bends, the radius of curvature should
be as wide as possible. Too narrow radius of curvature or sinuous areas will certainly result into
quick and localized wear and tear of the inner body of the hose.
