How is delamination in a container identified?

Delamination in a container is primarily identified by bulging and waviness in the panels. This condition occurs when the layers of material that make up the container's walls begin to separate. As a result, the outward appearance of the panels exhibits noticeable deformations, such as bulging or wave-like patterns.

These visual indicators are significant because they suggest that the integrity of the layers has been compromised, which can lead to further structural issues if not addressed. Delamination can be caused by factors such as moisture penetration or poor manufacturing processes, and recognizing these signs is critical for maintaining the safety and functionality of the container.

While obvious cracks, surface corrosion, and structural bends can indicate other forms of damage or wear, they do not specifically point to delamination as effectively as the bulging and waviness do. Understanding these nuanced indicators is essential for anyone involved in the reinspection and certification of intermodal dry cargo containers, as they help ensure the containers are safe for transport and compliant with standards.
