| Abstract: | The corrosion of overhead after - cooler tubes of a RFCC main fractionator is introduced. The problems in application of Ni - P coated tubes and 7910 dope （ expoxy amino resin） coated tubes in oil vapor service are studied. The corrosion resistance of Ti - nano polymer coating is described. The installation of tube bundles applied with Ti - nano polymer coating has solved the corrosion problem of overhead condenser tubes of dehydration tower. |
