Chloride Removal: Using ‘Recyclable Encapsulated Abrasive Media

Chloride Removal: Using ‘Recyclable Encapsulated Abrasive Media
Available for download

This paper presents results of multiple test programs that have been performed to determine the effectiveness of recyclable encapsulated abrasive media to remove chlorides during surface preparation. Tests published in 2002 concluded that this technology consistently achieves significant reductions of chloride levels in comparison to those achieved with conventional abrasive blasting.

This paper presents results of multiple test programs that have been performed to determine the effectiveness of recyclable encapsulated abrasive media to remove chlorides during surface preparation. Tests published in 2002 concluded that this technology consistently achieves significant reductions of chloride levels in comparison to those achieved with conventional abrasive blasting. However, those tests were conducted with new media and not recycled media; leaving questions regarding the effect of recycling and possible re-deposition of contaminates on the surface. Recent tests indicate that chloride removal can be efficiently performed while recycling encapsulated abrasive media and no detrimental effect on removal rates occurs with increased recycles; in fact, increased cycles showed a slight improvement in removal efficacy. Test results also indicate that blasting with encapsulated abrasive media can frequently reduce chloride concentrations to below typically specified levels. This process compares favorably in both cost and speed to other technologies, which often require a multi-step procedure such as abrasive blast, water or chemical wash and final abrasive blast to achieve specified levels of surface contaminants.

Industrial and marine protective coating systems are most commonly applied without incident and perform as expected over their anticipated service life. However, occasionally, a coating system will fail prematurely, for unexpected reasons, and with expensive consequences. This paper addresses those unexpected failures and provides reasons and remedies for such occurrences.

Challenges Linked to Use of Hybrid Coatings in the Offshore Sector

Polysiloxane (often referred to as ‘hydide coatings’) products have been one of the major technology platforms used in the European offshore sector mainly due ban on isocynate among several customers. The potential long-term performance of polysiloxanes coatings have also been a strong argument for this topcoat selection in NORSOK (501 – rev 5) systems. There have been several claim-situations with delamination in epically two-coat systems, but similar problems have also been seen on traditional NORSOK systems.
