A tapered plug should only be used when it is in an application where the pressure of the boiler will be acting to drive the plug securely into the tube (i.e.: plugging of generating tubes in the drums of a water tube boiler). We've also removed tubes from service by capping with the use of a butt weld or socket weld cap sized to fit the tube.
boiler start up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow Long-term Overheat Tube metal often has heavy external scale build-up and secondary cracking. Super heater and reheat super heater tubes commonly fail after many years of service, as a result of creep.

Open the feed water valves and the air valve. Fill the boiler with feed water to approximately 50 mm below normal water level. The water level rises due to expansion when the boiler is heated. If the temperature difference between the boiler and feed water exceeds approximately 50ºC, the boiler must be filled very slowly.
Start the boiler, following the appropriate start-up procedure included in this Manual. The boiler will be operated in the manual mode, low fire setting, for the duration of the boil-out Observe the open safety valve tapping, as the boiler is being warmed.
