Abstract
In a blowout preventer body having a central bore a method of reducing the size and weight of the blowout preventer body while maintaining an acceptable stress level at working pressure comprising machining a portion of the blowout preventer body to proximate the final dimensions, pressuring the blowout preventer body to a higher pressure than the working pressure of the blowout preventer body to yield high stress areas of the blowout preventer body, and relieving the higher pressure from the blowout preventer body such that when the blowout preventer body returns to the non-pressured state the high stress areas will retain compressive stresses and when the blowout preventer body is then pressurized to the working pressure of the blowout preventer body the stresses will be at an acceptable stress level.
