  • Page 138: Testing Hose Lines

    TESTING HOSE LINES Testing hose lines An essential factor in ensuring operational safety when handling L&W compressors is the proper testing of the hose lines used. Tests are necessary:   After assembly and before commissioning the hose line.  After accidents, changes (modifications) to the compressor system, longer periods of non- ...

  • Page 139: Recurring Test

    TESTING HOSE LINES Recurring test Since hose lines are subject to influences that cause damage during operation and can lead to dangerous situations, they must be tested recurrently at fixed intervals. The aim of recurring tests is to detect and repair damage in good time. The objective is to ensure that the system remains in a safe condition.

  • Page 140: Persons Qualified To Test Hose Lines

    TESTING HOSE LINES Persons qualified to test hose lines A qualified person is a person who, through his or her professional training, professional experience and recent professional activity, has the necessary specialist knowledge required for testing work equipment - in this case for testing hose lines. These requirements are defined in the Technical Rules for Industrial Safety TRBS 1203 "Qualified persons - general requirements"...

  • Page 141: Replacing Hose Lines

    MAINTENAN Replacing hose lines As a general rule, even when stored properly and subjected to permissible stress during use, all hose lines are subject to natural aging, which changes the material and composite properties and reduces the performance of the hose lines. This limits the service life of a hose line and the operator must ensure that hose lines are replaced at appropriate intervals.

  • Page 142: Service Life

    SERVICE LIFE Service life of L&W high pressure hoses When determining the service life or the replacement interval of the individual hose lines, the concrete specifications and recommendations of the hose line or machine manufacturer must be observed. Furthermore, empirical values resulting from previous tests done under the prevailing operating conditions on site are also relevant.
