Since Jan. 1970 the Los Angeles Dept. of Water and Power has suffered three major circumferential pipeline breaks in a portion of the newly constructed Second Los Angeles Aqueduct. In each case the pipe line failed in a brittle manner. Since the first failure, the department has conducted extensive metallurgical investigations, stress analyses, numerous tests on the steel plate, and a thorough analysis of welding procedures and techniques. Presented are the various factors pertinent to the breaks and recommendations based on the experiences and investigations.
