51316-7304-Evaluation of Protective Coating Performance in a Cyclic-Temperature Environment

Picture for Evaluation of Protective Coating Performance in a Cyclic-Temperature Environment
Available for download

Overview of coatings for a cyclic-temperature environment. Test method, including a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Factors to be considered for coating selection in the cyclic-temperature environment are discussed.c

A cyclic-temperature environment is recognized as a severe condition for coatings. In oil and gas plant facilities a dehydrator is a typical kind of equipment operating in the most severe cyclic-temperature environment ranging from ambient to 300 deg-C. For a dehydrator, three coatings (i.e., "a heat resistant silicone liquid coating", "an inorganic copolymer or coatings with an inert multipolymeric matrix liquid coating" or "a thermal sprayed aluminum coating") are typically applied.

However, no experimental data comparing the performance of these coatings, i.e., heat cycle stability and corrosion resistance, under standard test conditions have been reported. Furthermore, no standard test method has been established to evaluate the coating performance in a cyclic-temperature environment ranging from ambient temperature to 300 deg-C.

This paper summarizes an overview of coatings for a cyclic-temperature environment first, and proposes a simple test method which includes a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Finally, based on the test results and on information from recent process plant construction projects, factors to be considered for coating selection in the cyclic-temperature environment are discussed.

Keywords: downloadable, Cyclic-temperature, dehydrator, cycling, inorganic copolymer or coatings with an inert multipolymeric matrix, thermal sprayed aluminum, TSA, salt spray test, cathodic protection, blackening

Traditional internal lining schemes for the storage/transport of crude oil & refined fuels may no longer be appropriate. The aggressive nature of crude oil (high temp. & more sour), high purity refined products & increased use of biofuels demand better linings & more certain test results. The focus of this paper is to review the trends in test methodology from the early 1990’s to present.

New high-solids coatings are sometimes required to meet volatile organic compound (VOC) legislation. Lack of data on same needs accelerated test methods to evaluate performance. The test method must: • Be performed using commercially available equipment • Take a relatively short time period. • Correlate with real life exposure.

This paper will review the features and benefits of a new epoxy coating technology that allows for true epoxy-amine curing in a single-pack product. Performance versus traditional two-component epoxy products will be compared, and environmental and convenience benefits of single-pack versus two-component packaging will be discussed.
