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
