A demonstration of how easy it is to get clean stainless steel tubes (in this case tubes for liquid oxygen) with the tube cleaning solution provided by ALKA by the firing of special projectiles for tube hose and pipe cleaning.

A demonstration of how much soot and how many copper particles can be found in new insulated tubes.
With these copper particles, air conditioning system components are more likely to be damaged.

A demonstration of how you can verify the presence of soot in a 2 km copper tube coil. The soot creates when the pipe has not been properly degreased before its annealing in the oven.

Time required: 4 minutes. Ideal for quality control.
