Cathodic Protection
Cathodic Protection
(OP)
What is a reasonable or expected service life of an underground carbon steel pipe used in electric transmission that is cathodically protected? I recently observed a pipe segment that was in the ground for over 25 years that looked brand new. Much existing underground transmission pipe cable is 50 yrs old or more. Assuming an effective impressed current cathodic protection system, seems like the pipe could last forever with the transmission cable being the weak link. Your thoughts and experience would be much appreciated.
