Development and Test of Gas-Tight Transmission Line Terminals
Abstract
Transmission line seals in three sizes (1/4", 3/8", and 3/4") were constructed at the Naval Research Laboratory and subjected to tests to determine their suitability for use in the Naval Service. Reference (a) requested information and data on seals for 7/8" line. Glass sealing alloy tubing suitable for construction of 7/8" transmission line seals was not obtainable except by special order and payment of tool costs. Therefore no Seals of this size were tested. A pair of 1/4" and 3/8" seals were attached to 20-foot lengths of 1/4" and 3/8" line respectively, the lines filled with dry nitrogen and sealed. At the end of the test period, these lines were subjected to several temperature cycles. Seals were tested for leaks over a period of approximately eight weeks. Further, they were subjected to standard vibration and shock tests after which they were again examined for gas leakage.
