Chemical Cleaning is an Industrial Maintenance process to eliminate scaling and
contaminants:
In closed circuits by circulating a cleaning fluid.
By submerging the equipment in cleaning fluid.
Why perform a Chemical Cleaning?
1) Scaling on pipes considerably increases corrosion at the adherence points, damaging the pipes and in
the event of pipes with thin walls, causing leaks. Chemical Cleaning eliminates scaling.
It increases the life of the equipment
2) The heat transfer coefficient of the steel is between 15 and 400 times
higher than the coefficient of the scales deposited during normal equipment operation, reducing its performance regarding heat exchange. Chemical cleaning
eliminates scaling.
Improves the equipment?s performance
3) The The loss of a pipe?s load is inversely proportional to the cube of the
pipe?s diameter. Therefore, decreases in pipe diameters due to scale tanks reduce the flow and increase pressure loss, decreasing the performance of the equipment.
Improves the equipment?s performance
4) ) In certain installations scaling can be dragged into highly sensitive equipment causing break-downs.
Break-down prevention
5) During the dismantling of industrial installations, the pipes could be contaminated with chemical products, and before these go to the scrap
yard they must be decontaminated.
Environmental protection
6) When industrial installations are completely assembled their circuits can be contaminated with earth, sand, oil stains, rusted parts, which must be
eliminated to guarantee the correct functioning of the installations according to
specifications.
