Hydraulic hose lines
Storage and duration of use
Excerpt from DIN20066:2002-10
• For permitted loading, hoses undergo a natural change. This limits the dura-
tion of use.
• Improper storage, mechanical damage and unpermitted loads are the most
frequent cause of breakdowns.
• The duration of use of a hose line including any storage time should not
exceed six years.
Hose lines are to be replaced if/when,
• Damage to the outer coating up to the insert (chafe marks, cuts, cracks).
• The outer coating becomes brittle (crack formation).
• Deformation from the natural shape in the depressurised and pressurised
conditions.
• Leakage.
• Damage or deformation of the mounting fixture.
• Meandering of the mounting fixture.
• The lifetime has been exceeded.
Repair of the hose line using the implemented hose / mounting fixture is not
permitted.
Extending the replacement intervals given in the guideline is possible if the
inspection for safe-work condition is done in adjusted, shortened time frames,
if required and by competent personnel.
If there is an extension of the replacement interval, no situation may occur
which could result in injury of employees or other personnel.
Excerpt from BGR237:
Specifications for the hydraulic hose lines.
Normal specification:
Recommended exchange intervals:
6 years (operation duration including max. 2 years storage time).
Increased demands e.g. by
• Increased usage times e.g. multi-shift, short cycle times and pressure impulses.
• Increased exterior and interior (due to media) influences which significantly
reduce the lifetime of the hose lines.
Recommended exchange intervals:
6 years (operation duration including max. 2 years storage time).
