The unit’s performance needed excellent resistance to solvents, acids, and de-mineralised water. Polyglass VEF was recommended, as it has excellent hold up during application, providing exceptional chemical resistance, leading to a longer life of asset protection.
Chemical Manufacturing.
After an initial capital investment in a Regan unit, processing Sulfuryl chloride, hydrochloric acid gas, Sulfur Dioxide gas and chlorine, with an operating temperature range of -25°C to +40°C with the working temperature being on the cold side of the range, the customers issue was pitting and corrosion on the units that had been recently swapped out.

Corroserve has the experience and expertise to either coat from new or provide remedial coating to Regan units. The bespoke coating systems used, are determined by the operating conditions and mediums. Our coating systems have provided unrivalled levels of corrosion protection in the harshest environments for over 40 years. Corroserve is a member of the Corrosioneering Group which also includes specialist paints and coatings manufacturer – Corrocoat and research and development division – Corrolab. Working together, we provide the ultimate ‘one-stop-shop’ for our customers.
Abrasive blast the internals with to ISO 8501-1 to Sa2½ with a surface profile of 50 microns. Fill any pits using Corofill V. Apply Polyglass VEF to a WFT of 600-800 microns. 2nd coat of Polyglass VEF to a DFT of 1200 microns. Carry out thickness testing following adequate cure of coating. Post cured for 60-80°C for at least 8 hours to ensure full cure prior to entering service and provide full chemical resistance.
