When using a non-ASME rated tank for processes that require greater than 15 psi, risks include higher weld stress and potential premature weld failures (nozzle and manway weld joints are more susceptible to these failures). Deformation of the manway over time will cause leaks because the gasket does not correctly fit. In a worst case scenario an explosive failure of the manway, fitting, or weld seam can compromise the safety of workers. Violation of codes regarding pressure vessels can have far reaching implications—including tort liability, possible loss of insurance coverage, fines, and more—in the event of damage, injury, or loss from knowingly operating a tank that is not ASME rated.
