Chemical Treatment and Passivation of Pipes
“Passivation” refers to the process of chemical removal of iron contaminates left of the surface of stainless steel and other steel parts after machining. Passivation maximizes resistance to corrosion. A number of different passivation methods exists for various types of steel.
Assembled, welded and closed circuits, such as pipes, in order to be cleaned, must be flushed by circulating liquid through the pipes. The cleaning process is both chemical and physical. The minimum flow rate of the solution through the pipes should be at least one (1) meter per second. Pipeline flow rate and capacity must be considered as well as the diameter of the pipe.
Pipes should be tested for water tightness after installation and connection to the hoses that complete the system. Special pickling materials should be used to ensure the integrity of the system.
