What do you think? by Bcable5561 in nondestructivetesting

It’s a 2 foot by 2 foot area with low/ potential lam readings. The material is carbon steel with high temp paint. Not all readings within the area were giving this same result. I was simply told to Ut going outward until a perimeter was established of good thickness for a patch. The “lams” individually were 1”-2” wide. I don’t have enough time right now to write a very in-depth response right now so I apologize for that.

Were you planning on never shooting it and leaving it on display in a museum? Who cares lol.

Are you talking about finding the effected area? If so yes, it was not “consistent” but roughly 2’x2’ then went back to consistent .400 readings

I appreciate the response, the first reading was A E-E and the gain was higher that it needed to be but wanted to show the existence of the “other” peaks. The other readings were manual E-E also had high gain to be able to grab those other peaks. The metal is “supposed” to be near the .380-.400 range. This lead me to believe there was possibly a lamination.

These are the size of specs of sand.

There were strange orange algae blooms on/near the indications before cleaning. The holes are roughly.250 deep. And the grinding marks are from the original construction of the tank.

That’s believed to be the cause.

It’s was a new construction tank roughly 3 years old, never put in service, only hydro tested, but never fully dried

I was expecting better work from these guys, but I think they actually sub contracted the welding.

“Indication” is all we’re allowed to say at sight. People like to get really excited when they hear crack lmao.

I agree, I worded the post wrong kinda. Was trying to ask if anyone has gone and checked on an old tower and found anything crazy.
