Abstract
A turbine diaphragm adapted to be supported in a lower turbine shell component includes a first diaphragm half portion having a pair of diametrically opposed horizontal joint surfaces and a second diaphragm half portion having a similar pair of diametrically opposed horizontal joint surfaces. The first and second diaphragm half portions are identical and interchangeable. Each diaphragm half portion is formed with mounting slots for receiving a support bar engageable with the lower turbine shell component, and with identical joint bolt holes to thereby insure interchangeability of the first and second diaphragm half portions.
