How are orbital welds validated for CIP systems?
Weld coupon testing for surface roughness. Passivation effectiveness verification. Bacterial adhesion testing. Chemical resistance validation. Full documentation of all parameters.
What cleaning validation is required?
Swab testing for residual contaminants. ATP bioluminescence verification. TOC monitoring of rinse water. Endotoxin testing for WFI systems. Visual inspection under 200 lux lighting.
How are spray devices integrated into CIP piping?
Rotary spray balls for tanks. Fixed spray nozzles for pipes. Proper coverage verification. Flow-controlled supply lines. Quick-disconnect fittings for replacement.
What maintenance ensures CIP effectiveness?
