46 SEPTEMBER 2015 COATINGSPROMAG.COM Tere, the steel and ductile iron pipelines of the boil-of gas (BOG) compressors were to be prepped, primed, and coated. Te client specifcally requested for John W. Egan Co. to be the installers. At various thicknesses, the coating system can help to reduce or mitigate the consequences of temperature diferentials in various environments. "We had two diferent applications here: One was to stop the condensation on the cold side of the equipment, and the other was to provide safe touch for the workers on the other side," explained Belisle. Te two coatings systems required diferent thicknesses to achieve the required R-values, and, after the Tnemec lab used a program called 3E Plus along with the ambient conditions and surface and interior temperatures of the pipe, they came up with specifc systems: three 50-mil (1,270.0 microns) coats on the cold side to prevent icing and one 50-mil (1,270.0 microns) coat on the hot side (which was 200–300° F, or 93.3–148.9° C) to bring it down around 100° F (37.8° C). And because there were two compressor systems to be coated (each with one interior section and one exterior section), that meant that there were four separate areas and, therefore, stages of this project. After all, the client had to keep one compressor running/on call at all times! Working Conditions Equipment selection on this project was particularly important for the interior applications. "If there were to be any type of a leak, it could create a potentially explosive environment," Belisle explained. For the surface prep, then, they needed machines that would ofer the right results with low pressure and no sparking. For this crew and 750-square-foot (69.7 m²) project, the right To start, the 2- to 3-person crew pre-cleaned the units to Society for Protective Coatings (SSPC) Surface Preparation (SP) 1: Solvent Cleaning. Then they blasted them to NACE No. 3/SSPC-SP-6: Commercial Blast Cleaning.
