Heat exchanger was suffering from corrosion in their tubing and tube sheet areas. Corrosion was creating space between the tubes and tube sheet, which decreased the efficiency of the equipment.
Dura-Coat Chemical 200HT was applied not only to protect the surface from future corrosion, but also to seal any breaches between tube & tube sheet. The coatings high adhesive force (above 4500 psi) prevents corrosion, and its high chemical resistance protects it from the aggressive environment of platform rigs.
