Products
Chem-tect™ RB 300 series, a glass flake filled vinyl ester, provides excellent permeation resistance and high dielectric strength.
Environment
40-60°C, sea water
Challenge
To provide a long term solution for the corroded tube ports and tube sheet.
Chemco’s Solution
Tube internals were protected by inserting specially ordered silicon plugs to prevent abrasive blasting from damaging wall thickness. Abrasive blast as per required standard and remove silicon plugs and glue nylon tube inserts into position and then pitfill all deep cavities using RB 300 Series. We used the proprietary method to obtain a flat surface using RB 300 Series.
Results
An estimated replacement cost was in the range of $500K and this refurbishment is expected to extend the life for another 20 years. Chemco is available for all corrosion related issues with nearby ancillary equipment. For more information please feel free to contact Chemco on 1300 CHEMCO (243 626).
