Case Study – Refurbishment & Lining of Chemical Processing Vessel and Lid

A chemicals processing vessel and lid used in the manufacture of potassium bromate required a programme of refurbishment and lining with a suitable protective coating. The lid of the vessel had 10 access/sampling ports that all required preparation and coating.

As a first step the vessel and lid were abrasive blasted, both internally and externally, to achieve the required cleanliness standard before being thoroughly cleaned down to remove all dust and debris.

Polyglass VEF was  applied to a DFT of 750µm, VEF is formulated for immersed environments where superior resistance to chemical attack is required within the full pH range.

In order to provide advanced protection from abrasion a second coat of Armagel was applied. The externals of the vessel and lid were coated with Plasmet ZF to ensure all round corrosion protection.

The application of specialist protective coatings will significantly increase the expected service life of the chemicals vessel.
