Abstract:

The objective of this study was to evaluate commercially available glass pipes with conical flanged ends for application as transparent housings for underwater lights and instruments. Flanged-end glass pipes in diameters ranging from 1 inch to 6 inches and in lengths ranging from 6 inches to 36 inches were imploded under short-term and cyclic external pressure loading. Collapse pressure and recommended operational depth data are presented for one-way trip, round-trip, and cyclical applications. Recommendations for end-closure systems are also presented. One prototype light design and one prototype instrument housing design are described.
