Permanently bonding a pipe to at least one rail and to the transfer apparatus protects against which issue?

• A. Stray currents
• B. Corrosion
• C. Leaks
• D. Sparks

Answer: (A)

Bonding creates a continuous electrical path between the pipe, at least one rail, and the transfer equipment so everything stays at the same electrical potential. When stray electrical currents are present in the environment, they’ll seek the easiest path to ground. If the pipe isn’t bonded, these currents can flow along the pipe and connections, leading to corrosion or arcing during transfers. By tying the pipe to the rail and the transfer apparatus, any stray current is kept here and dissipated safely, preventing it from causing problems along the pipeline. Leaks are a hydraulic issue and aren’t addressed by electrical bonding. Corrosion can result from stray currents, but bonding specifically prevents stray currents from driving those effects, which is why the best answer focuses on stray currents. Sparks can be a consequence of potential differences, but the root protection provided by bonding is against stray current movement.
