Forge Bonding – Is There Any Specific NDE Method To Verify Integrity?

This segment addresses the specific NDE methods employed to verify the integrity of forge bonding repairs, particularly when dealing with storage tanks. While not always required, pressure testing becomes crucial in scenarios where liquid is present on the tank’s backside or when repairing floating roofs. This method involves inspecting the repaired area to ensure no leaks are present, sometimes with the customer conducting their pressure tests, as illustrated in one case involving a tower. The process requires the repair to hold a certain pressure level for a set duration, demonstrating the repair’s success and ensuring safety and reliability.

Hi I’m Don Cooper, the CEO and founder of innovator and today’s session is part of a series that we’re offering on above ground storage tank repairs. And today we are talking about the Forge bonding repair method.

Sometimes, but not generally, when we’re repairing tanks typically frequently there’s liquid on the backside or when they raise the level on the on the shell above the leak point it will be pressure tested at that point. So floating roof we’re most of the repairs we do on floating roof roofs is when there’s liquid on the backside of the roof so there’s a pressure already there. So when we leave the jobsite, we just want to inspect and make sure there’s no product coming out from under the plate. I did show one picture. Let’s see if I can I can’t go back to that. Were we the customer actually was responsible for the pressure testing it was on that pressure vessel this one yeah this one here on the upper right. This was on a tower and the customer wanted to test it because this was these were near leaks are thin metal so there was no pressure in this tower to test our seal. It actually had a large amount of h2 s gas in it so they did not this would have been they said if this thing springs a leak this towers there’s no one’s going up there we’re shutting down so but they wanted a pressure test because they said there’s no you’re not going to be any pressure when you install it. So that’s what this little fitting or fixture was welded on here. They applied air pressure and pumped it up to 15 psi and it had to hold had to hold exactly 15 psi for for an hour.
