Compressed Gas Cylinder Cleaning

Question: I'm interested in ceramic and glass sphere media for tumbling compressed gas cylinders to remove rust and organic contaminants. I want to clean these cylinders for oxygen service. My cylinders range from large (5' tall by 10" diameter) to medium (2' X 7") in steel to small (1' x 4") in aluminum. I'm primarily interested in doing a thorough job cleaning the cylinders without damaging them.

Response: The following recommendations would be appropriate:

• 5/32" x 5/16" KM Ceramic Angle Cut Cylinders Media - for the cleaning step
• 150 Mesh Aluminum Oxide Grit - to increase abrasiveness of tumbling process
• 5mm K-Polish Precision Ceramic Spheres - as a replacement for large glass beads (more durable and longer lasting)
• Kramco 1060 - Aluminum safe (even in concentrated form) cleaner and degreaser
