PRODUCT HOSES, TUBES AND COUPLINGS
Bursting hose, bursting threaded joints!
Danger to life from injection of product and from fl ying parts.
The service life of the complete hoses between product pressure generator and application
device is reduced due to environmental infl uences even when handled correctly.
Check hoses, pipes, and couplings every day and replace if necessary.
Before every commissioning, check all connections for leaks.
Additionally, the operator must regularly check the complete hoses for wear and tear
as well as for damage at intervals that he/she has set. Records of these checks must
be kept.
Undamaged complete hoses are to be replaced when one of the two following
intervals has been exceeded:
– 6 years from the date of the hose crimping (see fi tting embossing).
– 10 years from the date of the hose imprinting.
