Corrosion inside pipes can cause tuberculation, which forms small hemispherical lumps on the pipe walls. What is this condition called?

• A. Tuberculation
• B. Pitting
• C. Erosion
• D. Scaling

Answer: (A)

Tuberculation is internal corrosion that produces corrosion products into rounded nodules on the pipe wall. These hemispherical lumps protrude into the lumen, reducing flow area and increasing roughness. This form of corrosion is most common in iron pipes and differs from other forms: pitting creates small deep holes, erosion is wear away from flowing fluid, and scaling is mineral deposits lining the interior. The hemispherical deposits themselves are what give tuberculation its name.
