Which of the following is not an indication of excessive bolt loading on a flanged connection?

• A. Deformation of the flange surface
• B. Leakage at the flanged connection
• C. Cracking of the flange material
• D. Distortion of the gasket

Answer: (B)

Leakage at a flanged connection can occur due to various reasons and is not solely indicative of excessive bolt loading. While excessive loading may contribute to leakage, other factors such as improper installation, gasket failure, or material compatibility can also lead to leakage. Therefore, leakage isn’t a definitive sign of excessive bolt loading. In contrast, the other options directly relate to the physical effects excessive bolt loading would impose on the flanged connection. Deformation of the flange surface indicates that the flange has been compressed beyond its capacity, which occurs with excessive load. Cracking of the flange material often results from stress exceeding the material's yield strength due to over-tightening. Distortion of the gasket is another telltale sign of excessive loading, as it can lead to inadequate sealing and eventual failure of the joint. Each of these conditions directly reflects the consequences of excessive loading on a bolted connection, while leakage requires a broader analysis of joint integrity.
