Pipe Cleaning & Passivation
Pipe Cleaning & Passivation refers to the process of chemical removal of iron contaminates left of the surface of the interior of the piping and other parts after machining & welding. Passivation maximizes resistance to corrosion. A number of different passivation methods exists for various types of metals.
Assembled, welded and closed circuits, such as pipes, in order to be cleaned, must be flushed by circulating cleaning chemicals through the pipes.
