Apr 20, 2017 · Generally, the use of tell-tale holes assumes also that the vessel has a specified corrosion allowance. FYI, reinforcing plates put around nozzles on larger vessels normally have a tapped hole through them so the welds can be pressure-tested in initial construction and so that later leaks in the nozzle welds will be visible.
