For similar pressure vessels in industrial service (like 50,000 gallon tanks), we'd not let a unit like this be operated without a fitness for service test every ten years or so.
Any company that does fitness for service tests for industrial equipment could probably do the same tests (ultrasonic thickness, joint/weld testing, etc) and make a determination if the vessel is safe to keep using, but I'd expect that to be cost prohibitive.
