Abstract:

A program was conducted to determine the cause of the corrosion that was discovered in a number of aluminum scuba cylinders, and to determine whether the rupture strength of the cylinders had been degraded by the corrosion. An examination was made of 68 corroded cylinders received from Naval facilities. Rupture experiments were conducted on new cylinders and on the most severely corroded cylinders. Detailed analyses were made of corrosion products from selected aluminum cylinders, and of corroded and uncorroded material from the ruptured cylinders. It was concluded that the corrosion in the cylinders examined had not significantly reduced the rupture strength of the cylinders. Recommendations were formulated concerning changes in manufacturing specifications, cleaning procedures, and inspection procedures to provide increased assurance that corrosion will not progress to the point of significantly degrading the rupture strength of aluminum scuba cylinders.
