[Elecraft] Grounds... I know, I know... its a Dead issue BUT... (no Pun)

[Phil Townsend]

I really hate to bring it up again... But hear me out:

My A/C service entrance does not have a ground rod.
My house was built about 25 years ago.'
I pulled the service front panel and found the following:
All the grounds and neutrals are bonded to the metal chassis as they are supposed to be.
But there is no wire for a connection to a ground ROD!
It looks like they used a solid metal pipe that houses the big A/C wire inside of this pipe.
This pipe IS connected to the service entrance by some metal gland nuts.
The 2 1/2" pipe goes outside of the house and is buried underground. It goes off to a transformer that is about 100 yards away.
So my question: 
IS this pipe MY Ground rod?
