8.1.2 Cleaning results

The cleaning result depends on the following factors:

●

Temperature

●

Time

●

Mechanics

●

Chemicals

●

Degree of soiling

These factors can be combined in such a way as to make an optimal cleaning result

probable.

8.2 Passivation

Before a system with long pipes and tanks is commissioned, it usually needs to be pas-

sivated.
Valve blocks are usually excepted from this.
Passivation is usually carried out with nitric acid (HNO

) at about 80 °C (176 °F) in a

concentration of 3 % and a contact time of 6 to 8 hours.
