Application of JCTZ-2 Anti-corrosion Coating to Refinery Heat Exchangers

In order to enhance the anti-corrosion properties of carbon steel coolers and exchangers and ensure the life of the equipment, an organic coating, JCTZ-2 coating, was prepared. The coating process of JCTZ-2 coating for coolers and exchangers was developed. The results indicate that the JCTZ-2 coating has excellent anti-corrosion properties and is suited to be used in complex corrosion environments. The life of the coolers and exchangers was lengthened for more than 2 years after JCTZ-2 coating was applied.
