In the oil fields of Venezuela’s North District, one common characteristic is the high temperature of oil (up to 150 °C), which has a direct impact on the performance of the pipelines’ coating. Internal and external corrosion are the common problems. In the past 10 years, liquid epoxy resin-based coatings have been used to mitigate the external corrosion of pipelines. Very little is known, however, about the degradation of these coatings at high temperatures, and it has been a challenge to determine an appropriate test protocol to qualify coatings at high temperatures. To evaluate the performance of different coatings at high temperatures, five samples coated with various liquid epoxy resin coatings were put in a convection oven at 150 °C for two years and then evaluated by several test methods to classify the thermal degradation of the coating systems. The samples show that the conditions influence coating embrittlement. Results of thermal and thermo-oxidative aging of the five different liquid coatings systems are presented in CORROSION 2014 paper no. 3650, “Degradation of Liquid Epoxy Resins at High Temperatures,” by O. Centeno.
