This paper reports that determining the internal pressure that a tubular joint can resist without leakage may reveal the reason why some API 8-round threads leak. The calculation presented here puts the concept in the right perspective and will aid an engineer in making a decision that can help avoid costly leakage in tubular strings in oil and gas wells. The method is based on recent technical papers published by ASME. The main concept taken from the ASME papers is that no leakage will occur if the interface bearing pressure is equal to or greater than the pressure differential at all times. Also these pressures should be within the elastic range.
