SEGMENTED RING-NUT FOR GASKETED PRESSURE VESSEL OPENING

摘要

An internally threaded, segmented nut and conical bore for a pressure vessel are used to make removal of studs securing covers over openings through the pressure vessel wall. The segmented nut has a conical upper surface to mate with a corresponding surface of the conical bore when the stud is threaded through the internal thread of the nut and a load is applied. The segmented nut is easil y replaced and the stud is easily removable due to the shape of the nut and bore. The segmented nut eliminates drilling and rethreading the bore to repair damaged threads.
