A number of acrylic reactors had become susceptible to corrosion around the heating elements. Weak areas within the reactor had penetrated the steel, leading to several live leaks.
Previous repairs to the reactors had been successful and were performing well. However, new weak areas within the reactor had penetrated the steel, leading to additional live leaks. Belzona UK were requested to propose a long-term solution.
Once leaking areas are identified and marked leaking areas, the surface was grit blasted to achieve the required substrate standard of cleanliness and a profile of SA 2½ with a minimum of 75µm.
All substrate defects within the area are repaired using Belzona 1511 (Super HT-Metal), including surface reprofiling and filleting where necessary.
Belzona SuperWrap II system was then applied over the entire area in three layers with a 50/50 overlap design, before wrapping with consolidation tape.
Finally, Belzona 5871 is applied. Belzona 5871 is a thermally insulating coating, providing protection against contact-burn injuries, whilst also eliminating corrosion and problems associated with Corrosion Under Insulation (CUI), resulting in improved safety, durability and efficiency.
The integrity of the reactor was restored, offering long term protection against the effects of corrosion under insulation. The cool-to-touch solution also reduces heat on metallic substrates to below 60°C, eliminating risks of contact-burn injuries.
