The carbon steel test pieces are suffering from severe corrosion; could everyone help identify what’s causing this? Thank you.

Installed on the central air conditioning cooling water system
Is it caused by the mounting position of the plate? There is no water flow to wash it away.
If so, how should the hanging plate be installed? Thank you all.
Given the conductivity value and chloride content, if it is not deionized water being used, it is normal for carbon steel to corrode
Since the cooling tower is open, could it also be related to the dissolved oxygen level in the water?
How is that possible? How can air-conditioning water cause corrosion? It’s probably condensate water; distilled water has a similar effect, and corrosion should be minimal, unless your factory uses water-cooled units that rely on circulating water
Water-cooled chillers use cooling water and chilled water, not the condensate water you mentioned.
1. At first glance, there don’t seem to be any major issues with water quality control； 2. A large amount of sludge appeared on the test sample; it is recommended to check whether bactericides are being added properly (the total bacterial count in the water quality needs to be verified), measure the SS level in the water, and determine whether the test sample is located in a stagnant water area. The test sample should generally be hung in an area with a flow rate of 1 m/s ；
