Understanding the Difference Between NDT and NDE
In the industrial steel industry, ensuring structural integrity and coating performance is critical. That’s where Non-Destructive Testing (NDT) and Non-Destructive Evaluation (NDE) come in. While these terms are often used interchangeably, they serve distinct purposes.
NDT
Refers to inspection methods that detect surface and subsurface defects in materials—such as ultrasonic testing, magnetic particle testing, and radiography—without causing damage. This process ensures coatings and substrates remain intact while identifying issues like corrosion, cracks, or adhesion failures.
NDE
On the other hand, goes beyond flaw detection. It includes analysis and assessment, helping to determine the extent of defects and predict future performance. This is essential for proactive maintenance and long-term asset protection.
Failing to perform these tests could lead to coating failures, substrate deterioration, costly repairs, and even structural hazards. Undetected defects may result in premature corrosion, safety risks, and non-compliance with industry standards. By integrating NDT and NDE into our services, we help clients maintain safety, compliance, and durability in their industrial coatings.
