Which issue can arise from flange leaks in certain fluids?

• A. Galling of bolts and nuts
• B. Bolt lengths to shorten
• C. Bolts to crack or corrode
• D. Bolting stresses to decrease

Answer: (C)

Flange leaks in certain fluids can indeed lead to bolts cracking or corroding. When a fluid leaks from a flange, it often indicates an issue with sealing or with the mechanical integrity of the bolted joint. If the fluid is corrosive—such as acidic or saline—this can accelerate the corrosion process on the exposed areas of the bolts. Moreover, leaks can also result in areas of stress concentration, causing mechanical fatigue over time. The presence of leaked fluid can create a corrosive environment that compromises the materials used in the bolts and nuts, leading to premature failure. This is especially true if the materials are not inherently resistant to the specific fluid. Therefore, monitoring for leaks is essential not just for maintaining the integrity of the system, but also for ensuring the longevity of the bolting hardware. The other potential issues—galling of bolts, shortening of bolt lengths, and decreased bolting stresses—are not directly linked to flange leaks and the fluid’s characteristics in the same way, making the risk of bolt cracking or corrosion the most relevant and significant consequence of flange leakage.
