Problem: Drilling pipe sits for prolonged periods of time in marine conditions. While the pipe is generally covered, it is still subject to a great deal of salt water spray and is always damp with sea water. The salt water from the ocean causes corrosion quickly, damaging the pipe both on the interior diameter and the outside diameter.


Effect: If the corrosion becomes too severe, the strength of the pipe is compromised and must be recycled and replaced leading to unnecessary waste, downtime and of course costs. Where the pipe has not been too severely damaged, it must be cleaned of all red rust before going back into service leading to added labour, time and costs.


Recommendation: Using a solvent based product will not allow for the long term stor-age of these pipes as it will evaporate and leave the metal unprotected. A wax oil or other more sold barrier will not do because the pipes are bundled and stacked and with the constant rubbing the hard coating will be compromised leaving unprotected steel. It was recommended to use Krown KL-73 Corrosion Inhibitor. This product will not evapo-rate and has the ability to heal over itself if scraping is to occur. Additionally, having this solvent free product minimizes any environmental impact where solvent based products create environmental and health concerns.


Result: The pipe that was already in service and was rusting was taken to a blast shop and cleaned. From there the KL-73 was applied and the pipes were taken to be stored. The pipes have been in use and storage for the last 3 years and are in “perfect condi-tion” according to the customer.
