Corrosion Resistant Underground Pipe
Corrosion Resistant Underground Pipe
(OP)
I just wanted to check if anyone had any ideas of what the new underground pipe treatment was to prevent corrosion. I have to install a small amount of underground pipe and think cathodic protection might be overkill.
The only real pipe that I know to apply is carbon steel pipe with coal tar epoxy and a wrap with special joint coating and taping.
Anything else out there that I should be aware of that works better, is cheaper, etc.?

I have a couple of pipes to install with a number of process fluids going through them:
- nat. gas (3")
- clean water (8")
- white water ( for paper machines ) (12")
Just looking for ideas...
I wasn't considering HDPE due to short length. I just didn't know if there was some new pipe coating out there...

We are currently installing some. If you use a ditch witch, or plow, you can really install it fast.

However, technology is advancing almost every day... Depending of service function of your pipe, I beleive ductile iron is the best choice - manufacturesrs sell pipe for undergorund installation with surface protection included. Even sandfill requirements are not so strict as this pipe is really robust.
HDPE pipe also does the job - can be used for virtually anything: water, gas, sewer (only high temperature limitations apply).

In this same area, I need to relocate some process sewer lines...
One line coveys waste with a PH = 2.0, the other two lines carry waste with a PH = 10.5. HDPE should be a no brainer, but the waste temperatures can reach 150-160.
