5.5 Inspection and replacement intervals of hoses
- After each operation the hoses have to be checked for external damages, cracks,
kinks and bubbles!
- The operator has to replace the hoses in appropriate period of times, even if there are no
visible security defects on the hoses.
- The hoses have to be replaced 10 years as from date of manufacture at the
latest (see marking on the hose)!
Hoses are subject to a natural aging even if they are stored correctly. Therefore, their
storage and service time is limited.
- Hoses have to be checked by a skilled person before the first putting into
operation of the technical device and afterwards at least once a year for their
safe working condition.
A skilled person is somebody having sufficient knowledge concerning hydraulic hoses
due to his special training and knowledge. He/she must be acquainted with the local
safety working conditions, accident prevention regulations, technical regulations and
approved standards (e.g. DIN-Standards), so that he/she is capable to estimate the
safety working conditions of the hydraulic hoses.
5.6 Examples for possible defects of hoses
- Damages of the surface and the interior (e.g. chafe marks, cuts or fissures).
- Embrittlement of the surface (fissuration of the hose material).
- Deformations, which are not in accordance with the natural shape of the hoses, in
pressureless condition or under pressure or in case of bendings, e.g. separation of
material layers, blister formation, squeezing or break spots.
- Leakage points.
- Instructions for installation were not observed.
- Emerging of the hose from the end fittings.
- Damages or deformations of the end fittings which deteriorate the function and stability of
the end fittings or the connection between hose and end fitting.
- Corrosion of the end fittings or the metal inlets, which deteriorates the function and stability.
- Storage and operation periods were exceeded.
