Progress report for the design criteria for piping and nozzles program for the two quarterly periods July 1--September 30 and October 1--December 31, 1975
The activities and accomplishments of the Design Criteria for Piping and Nozzles Program during the last six months are reviewed. Precis are given of the reports published by program personnel about stresses at nozzles in spherical shells, about stresses at openings in cylindrical pressure vessels, about stresses at and stress indices for nozzle attachments, recommending stress indices for socket-welding fittings, measuring and analyzing stresses in cylinder-to-cylinder junctions, about stresses in flat plates with attached nozzles, and about stresses in and fatigue failure of forged tees. Summaries are also presented of work in progress dealing with the development of stress indices and flexibility factors for elbows, the development of code rules regarding isolated and closely spaced nozzles in cylindrical pressure vessels, procedures for analyzing the design of lugs attached to straight pipes, the analysis of stresses in flanged joints, load-limit and fatigue studies for elbows, and the elastic-response and fatigue-life behavior of forged tees.
