Leakage of water from valve stuffing boxes /

The leakage of water from the stuffing boxes of four commercially available valves was measured under simulated power reactor conditions. Average leakage rates between 0.1 and 10 lb/yr were measured for three fully open valves of 3/4- to 6-inch size during a test in which they were pressure and thermal cycled 100 times to 1000 psig and 240©�C. The average leakage during a test in which a 3-inch valve was opened and closed 1100 times at 260©�C and 850-1000 psig was 30 lb/yr."Equipment, Methods, and Techniques (TID-4500, 15th Ed.).""Printed for the United States Atomic Energy Commission Contract AT(07-2)-1.""January 1961.""DP-538."Includes bibliographical references (p. 12).The leakage of water from the stuffing boxes of four commercially available valves was measured under simulated power reactor conditions.
