Glycol Piping

If the threads are torn or questionable start with a new fitting or re-thread the pipe.

I like a few wraps of GOOD teflon tape and the blue Leak Lock from Highside Chemical.

Glycol is a tough fluid to keep inside the pipes.

To late to consider press fittings?

    Glycol Piping

    I have a big glycol piping job that is spec'd to be done in screw pipe. What do you think is the best kind of pipe sealant. I've heard quickwick is NG. Any suggestions. The supply house says to use Permatex 14D.

    Glycol makes an excellent leak detector....

    It will find places that no other fluid can, due to low surface tension despite higher viscosity.
    There was a thread on this a couple of months ago I think. I initiated one also. My office practice is to weld, solder or braze all glycol piping joints and not to use screwed piping. The mess a leak would make is intolerable.

    Where glycol must be screwed, I believe we allow Rectorseal 7 but there are others I am sure.

    Now, your marching orders are obviously immune to my pleadings, so I will leave it to the more learned practitioners to direct you to their preferred or correct pipe dope.

    For screw pipe we always use permabond it very expensive but works real well. I put a candle factory in with 3000 screw joints and only one leak. Everything over 2" was welded everything under was screwed

    3,000 Screw Joints in a Candle Factory, Larry?

    And NO wick?

    I live for irony... this is too much.

    Speaking of Janet

    and screwed joints in the same thread, Bruce? Not me. Won't go near that one!

    yes, it's to late. The engineer spec'd the pipe,valves and fittings and wants what he wants. Called the permatex company and they said use Permatex 14D,which is a form of liquid teflon. We'll see what happens when the installation is done and tested.
