SS304 Corrosion or Byproduct of Thread Lube
SS304 Corrosion or Byproduct of Thread Lube
(OP)
What is causing this and is it a cause for concern? (See pic) We have 304 stainless pipe, bolts, nuts, & washers (per submittal) submerged in a storage tank holding treated, chlorinated drinking water. pH is 7.7. Chlorine residual is 1.7ppm. Pipe was installed about 6 months ago. Tank was brought off line and drained to inspect another item and this was found. Posts elsewhere suggested a reaction to thread lube, but I found a post here about Chloride induced Stress Corrosion. Any thoughts?
thanks
thanks

it seems that you've a terrible welding and that some of the lube is coming out of the weld (the two small ball in the middle of the picture) and also that you've corrosion on the internal wall of tank.
Sure that this is potable water and someone drink it?

Nuts and bolts are mass produced crevice corrosion fixtures.
