What is the minimum number of straps required per complete stack of ductile (Griffin) pipe?

The correct choice is based on the requirement for securing ductile (Griffin) pipe stacks effectively. For such materials, which are often heavy and can shift during transport due to their circular shape, adequate securement is crucial to prevent them from rolling or becoming destabilized.

Ductile pipe typically has a larger diameter and weight, making it more susceptible to movement without proper restraint. Using a minimum of five straps ensures that there are sufficient restraints in both the horizontal and vertical directions. This helps to maintain the integrity of the stack during transit by preventing sliding, rolling, or shifting.

In contrast, fewer straps may not provide adequate support, leading to potential safety hazards, equipment damage, or cargo loss during transport. Therefore, understanding the characteristics of the load and the requirements for securement is essential for safe transportation practices.
