This study analyzes the Remaining Life Assessment (RLA) of coating on a continuous nozzle by comparing coating application methods (powder coating and spray coating) and substrate types (aluminum and galvanized). The dry film thickness (DFT) was measured non-destructively using a DFT gauge in accordance with ASTM D7091 to obtain the initial thickness and the current thickness. The thinning rate was calculated using CR=(t1−t2)/Δt, while the remaining coating life was determined based on the API 581 approach using RL=(tcurrent−tminimum)/CR with a minimum thickness of 10 μm. The results show that the Powder Coating–Galvanized combination has the lowest thinning rate of 1.50 μm/month and the longest remaining life of 92.7 months. In contrast, Spray–Aluminum exhibits the highest thinning rate of 3.00 μm/month and the shortest remaining life of 40.3 months. These findings confirm that powder coating and galvanized substrates are more effective for long-term protection.
