A deep crack found at the local refinery has me all in on ultrasonic testing

I used to think a quick look over a boiler tank was enough to call it safe. Then the refinery just a mile from my house had a scare during a shutdown. They found a crack hidden deep in the steel, completely invisible from the outside. The team there used an ultrasonic scanner and caught it before it blew. Hearing about that near miss from the guys on site really got to me. Now I push for that kind of check on every tank we handle. It adds maybe an hour to the job, but it stops big problems. Seeing it happen right here in my town made that lesson stick.

Honestly, we caught a bad crack in a small tank with that scan, so it's worth it to me.

It's like @kimfisher said, you find the same thing with home repairs. Skip the inspection to save a few bucks and you always end up paying more later.

Isn't the real issue how you define low risk? A small tank failure might not blow up a whole plant, but a bad leak could still cause a serious spill or a fire. I've read reports where a small chemical tank leak led to huge environmental cleanup costs. That extra scan can pay for itself by avoiding that mess.

You said they "caught it before it blew," and that's great for a big refinery. But pushing for ultrasonic on every single tank feels like overkill. I've seen small shops go under because they priced in all this extra testing for simple storage tanks that just don't need it. A good visual and thickness check is still the right call for a lot of jobs. Why add cost and time when the risk is so low?
