Acceptance Testing for Coatings in Insulated Service

Acceptance Testing for Coatings in Insulated Service
Available for download

Generic descriptions of a coating material does not always ensure that it will perform in the CUI service. Testing and acceptance criteria will help owners to ensure that specific coating materials can provide service as required in industrial CUI environments. The intent of these test procedures is not to rank coatings, but test and accept coatings for use in specifications for actual application.

Generic descriptions of a coating material does not always ensure that it will perform in the CUI service. Testing and acceptance criteria will help owners to ensure that specific coating materials can provide service as required in industrial CUI environments. The intent of these test procedures is not to rank coatings, but test and accept coatings for use in specifications for actual application. Owners of refining and petrochemical facilities can have a tool for coating selection for use in CUI. This paper1 will present a potential methodology for testing and acceptance of coatings for insulated service. Initially four, both continuous and cyclic service thermal conditions over a wide range of temperatures, mostly as developed within NACE SP0198, will be described in CUI classifications. Appropriate test methods will be discussed to evaluate the coatings’ ability to operate within the service requirements for each CUI classification. These thermal service conditions can include corrosion resistance during project development, during periodic shutdowns, or during temporary mothballing of the facility, as well as during thermal shock, thermal cycling, immersion, and boiling water. Optional testing for cryogenic service and specific brand/insulation material testing will also be described. Potential acceptance criteria for each test will be provided.

ADHESION TESTING How much is sufficient?

Product Number: 51218-161-SG

Publication Date: 2018

Pull-off adhesion testing of coatings is commonly used for product testing and qualification as well as quality control / quality assurance. However, initial adhesion values do not necessarily correlate with service life of coatings or their corrosion protection performance. Adhesion of several product chemistries to steel is examined in this study before and after immersion exposure. Results are presented within the context of laboratory corrosion testing in an effort to investigate the significance of adhesion testing in modern lining systems.

The control, mitigation and prevention of corrosion in environments ranging from mildly corrosive to severe atmospheric conditions to underground exposures (such as pipelines) to chemical spill and fume exposures has long been focused on the use of thermosetting polymers such as epoxies, polyesters, vinyl esters and urethanes. For the most part these materials have worked reasonably well in applications such as structural steel and equipment coatings, architectural paints, vessel linings, concrete coatings, secondary containment linings, and floor toppings.

Pull-off adhesion behaviors of 15 coating systems in three groups were studied utilizing test method ASTM D4541. Three groups of coating systems included coating systems with organic or inorganic zinc-rich primers, polymeric polyurea coatings, and overcoating systems applied on an existing coating system.
