44 APRIL 2017 MATERIALS PERFORMANCE NACE INTERNATIONAL: VOL. 56, NO. 4 axalta.us/powder 800-247-3886 Capable of operating at temperatures up to 200 o C Exhibits extreme corrosion protection against high levels of H 2 S and CO 2 Provides superior corrosion protection in severe downhole environments Nap-Gard ® HIGH TEMPERATURE INTERNAL PIPE COATINGS COATINGS & LININGS ESSENTIALS Guide Helps Estimate Cost and Service Life for Protective Coatings To help coatings engineers and specifiers determine candidate protective coating sys- tems for particular industrial environ- ments, NACE International members Jayson Helsel and Robert Lanterman devel- oped a practical guide, "Expected Service Life and Cost Considerations for Mainte- nance and New Construction Protective Coating Work" (CORROSION 2016 paper no. 7422). is guide discusses commonly used generic coating systems and the ser- vice life for each in specific environments; current costs for materials and their appli- cation (both shop- and field-applied); and guidelines for calculating installed system costs. e authors comment that specific job costs will vary depending on the charac- teristics of a project, and note that the guide's purpose is to present a practical, easy-to-use document to identify, compare, and select protective coating systems that are cost-effective for specific environments. To identify the costs of surface prepara- tion, coating application, and materials for typical industrial environments, as well as the available generic coatings used in those environments and the expected service lives of those coatings, a survey was imple- mented to collect information from major protective coatings manufacturers, steel fabricators, painting contractors, and end users. Cost data were developed from col- lected data as well as common industry cost references. e authors use a "practical life" main- tenance approach in the guide for project- ing the life of the coating system, which estimates the service life as the number of years before first maintenance painting should begin—when the coating exhibits 5 to 10% breakdown and active rusting of the substrate is present—rather than the time until a coating system needs to be replaced. Data tables in the guide for the esti- mated practical service life of coating sys- tems include information such as generic
