Which pipe diameter is least likely to fail during a strength test using OFN?

When considering the structural integrity of pipes during a strength test using oxygen-free nitrogen (OFN), the diameter of the pipe plays a significant role in its ability to withstand pressure without failure. A larger pipe diameter generally allows for a greater surface area that distributes the stress more evenly, thereby reducing the likelihood of a failure under testing conditions.

The 1-inch diameter pipe is sized in such a way that it strikes a balance between managing pressure and maintaining structural strength. As the diameter increases, the material providing structural support is more effective at handling the stresses applied during the testing process. This means that while smaller diameter pipes can become over-stressed more quickly, especially under high-pressure conditions, the 1-inch diameter is robust enough to endure the strength testing while minimizing the risk of failure.

In contrast, smaller diameters would be more susceptible to deformation or rupture at lower pressure levels due to the increased concentration of stress. Options such as 0.5 inches might experience failure sooner during such a test due to their limited capacity to withstand stress. Similarly, larger diameters provide greater strength, but the 1-inch diameter represents an ideal balance for typical applications in F-Gas practice.

Thus, choosing the 1-inch pipe diameter in this context indicates a careful consideration
