Question

Accepted Answer

NDT tests commonly used in heat exchanger maintenance include visual inspection, dye penetrant testing, magnetic particle testing, and ultrasonic testing.

Visual inspection is the most basic NDT test and involves a thorough visual examination of the heat exchanger.
Dye penetrant testing involves applying a liquid dye to the surface of the heat exchanger and then wiping it off to reveal any cracks or defects.
Magnetic particle testing involves applying a magnetic field to the heat exchanger and then applying iron particles to the surface to reveal any cracks or defects.
Ultrasonic testing involves using high-frequency sound waves to detect any defects or corrosion within the heat exchanger.
