When driving the equipment originally, should water flushing be done first or purging and blasting?

For the initial startup of chemical processing units, should water flushing be carried out first or purging and blasting?
First, pressurize the pressure vessel and pressure pipelines, then carry out steam blasting for purging, and finally conduct water testing.
It is generally done in the order of pressure testing, purging, and target shooting.
Using water falls within the scope of testing; it’s just that the relevant processes are operated using non-production materials
Before the water flushing process, isn’t there a water wash? Take the distillation system as an example: should industrial air be used for blasting first, or should water washing be done first?
It’s just a water rinse; it’s not combined transportation
It’s only applicable to the fractionation system
First, carry out blasting in an industrial style, and then wash with water； After the water flushing is complete, water commissioning is usually carried out.
For new refinery units, the principle is to carry out blasting first and then water flushing.
First, purge the pipeline with air, then carry out water testing
