This post was last edited by sunjl1981 on 2013-1-6 23:59 The salt water of our unit is still exquisite and the old technology is the Doyle clarification barrel + sand filter. The sand filter has been severely corroded by electricity. The bent pipes often corrode and perforate, and the leak repair welding is not very effective. The salt water is forced to stop frequently. How can we slow down the corrosion? ? , , -
The original poster may consider changing the material to see if repair welding will not solve the problem. I have encountered electrochemical corrosion of pipelines here, and repair welding has no effect, because the electrochemical corrosion in salt water is quite serious, especially pitting corrosion, forming more small holes. If not repaired, it will be more serious, but if repaired, there will be new problems, and stress corrosion cracking will form in the welding joint. So it’s best to change the material.
