Yes, that's the intent with the heavy coupling; corrosion allowance. Also a good heat sink against distortion during welding.
Thank you again my friend. Very helpful.
Thank you moltenmetal for your response. It sounds like less of a corrosion issue than I thought. If we can expect 10 years or more I think that would acceptable.
I'm hesitant about using the carbon steel gland however, as it may corrode at some point potentially causing a leak and...
Good afternoon all. I am trying to solve the following problem:
We insert an electrical harness through the shell of a potable water tank to operate a submerged 110V electric motor. We penetrate the tank wall with a carbon steel coupling and use a stainless steel sealing gland on the interior...
