Uniform corrosion (also called general corrosion) is the most common form of pipeline degradation — characterized by relatively even material loss across a large surface area.

Uniform corrosion (also called general corrosion) is the most common form of pipeline degradation — characterized by relatively even material loss across a large surface area. While less aggressive than localized corrosion types (pitting, crevice), uniform corrosion progressively reduces wall thickness, eventually compromising the pipeline’s pressure capacity and structural safety.

Uniform corrosion is driven by continuous exposure to corrosive environments — including aggressive soils, moisture, acidic fluids, or inadequate cathodic protection. The predictable, gradual nature of uniform corrosion makes it manageable through regular wall thickness monitoring.

Detection methods include ultrasonic testing, MFL pigging, and aboveground inspection. EMPIT’s CMI technology provides continuous corrosion profiling along the pipeline route — detecting uniform wall loss and distinguishing it from localized defects. This comprehensive corrosion mapping enables accurate remaining life calculations and optimized maintenance scheduling.
