can this heat tape be used on a pvc pipe used in a condo for high pressure fire sprinkler system?

Sorry I can't help much on this, except it can be used on plastic pipe successfully.

Were I you, I would contact the manufacturer of the heat tape or the manufacturer of the pvc pipe. There is a new kind of anti freezing "tape " that is being recommended. It is a copper wire wrapped in some kind of insulator. I am only a consumer.

I have no experience with high pressure PVC uses. If the pipe is sturdy enough for high pressure, I can't imagine how proper use of the tape would damage it. But---why in the world is a safety system pipe exposed to freezing conditions??

All you talking about a thermostat? Not sure what your referring to, but yes you can . Not sure exactly what you are trying to overcome. For a sealing application l would use rtv silicone or Teflon tape.Normally l use an tiseez on bolts or blue locative.

Having grown up on a farm in Minnesota and used heat tapes for most of my life, the answers from my own experiences include: 1. The tape can be wrapped around plastic (PVC) pipe. 2. You have to insulate the pipe wrapped with the heat tape using foam purchased by the foot or in 6-10 foot lengths. The insulation can come in 3/4 inch or 1 inch size and you probably need the 1 inch foam insulation to cover not only the pipe but the heat tape as well. 3. The tape is sealed and will most likely get wet at some time and I've never seen this causing any problems with the tape operation. Keep in mind that this a very low voltage system and does not get burning hot, only the slightest bit warm. For that reason, the heat has to be held in just like you would when laying in bed on a cold night, you bundle up and keep the blanket over you to keep warm.

Not really because its tape if you are looking for a "marine grade connector" that is different. there is a bit of glue inside of those that melts to give a waterproof seal. This is more for connecting loose wires for example in a car / cars wire harness. That said, if you were looking for a water resistant seal, if applied properly, I don't see how water would get in once heat was applied and it shrunk

I guess 6 feet of heat tape is 6 feet no matter how you work it. Wrapping the tape around a straight pipe you might get a bit over 4 feet of pipe wrapped.

I use this product on a outside sprinkler junction with pvc pipe. It works well. I really not sure about the use you are suggesting. It is rather inexpensive, and you could try! Good luck

This tape is absorbing any paint very good and I've just check it but I don't know about tape compatibility with high temp paint when it will be heated.

The directions say the thermostat will kick on at 38F and turn off once the pipe is heated to 45F. That means the tape itself will be in the 80 to 90 degree F until the pipe gets to 45. If the thermostat gets stuck open and it is a pex water pipe, you might melt the pipe. However, I'm more concerned about it NOT working at all simply because a very hot tape will probably trip the house electric circuit breaker feeding that socket before it does any damage. Do not over insulate the heat tape. Follow the directions. You want the heat transferring to the water pipe as quickly as possible. The thermostat should be located where the pipe will have the HIGHTEST temperature from the heat tape (that is the highest elevation from the ground to the house). Don't cover the heat tape with those foam insulator type tubes. They are a fire hazard. Use fiberglass and wear a filter mask, goggles and one of those 3M paper coveralls that cover your body and your head as well as gloves. Care must be taken around fiberglass insulation to avoid breathing the stuff or getting it on your hands or face. I've had my heat tape two years now and it still seems to be working. You are supposed to test it with a bag of ice on the thermostat every fall to see if it works as well as unplug it in the spring but I never have. I just check the cold water. I know if it's nearing freezing or not. When that happens and it stays cold, I'll know it gave up the ghost and I need to keep the faucet slightly open when it's below 20 degrees F or so until I replace the heat tape. Hope this helps.

For shower valve and similar usage (non-boiling), I would use PTFE tape or PTFE paste. (http://www.amazon.com/Ampro-A1441-PTFE-2-Inch-260-Inch/dp/B003YL4CJC/ref=sr_1_2?ie=UTF8&qid;=1418998557&sr;=8-2&keywords;=PTFE+tape).The Permatex 80019 Aviation sealant, I use it on fuel and oil lines.

I think the answer depends a lot on the size of the pipe, the severity of the weather, and how often the pipe is used to transfer fluids or if it is under pressure 100% of the time. The other answers all have merit, and the newer heat tapes work better than those 40 years ago. Always insulate and then i recommend waterproof with a layer of plastic (4mil) closed with Duct tape. I did the insulation and waterproofing times two and never went under the trailer again while in Connecticut in colder times.

i doubt it- the hose would squish in when you try to snug the tape down. if you used this to cover one of those metal 'hose repair fittings ' that always leak it would likely seal. It didnt seal a leaky pipe joint on a hot water boiler line - just dripped out around it. Good luck

Yes , it could be used on PVC pipe, it doesn't get hot enough to damage PVC pipe.

I do not think it matter how long the heat tape is as long as the wire is use as heat tape, I hope this help

I don't think it would work on water pressure a pipe like that would have.I used it on a garden hose, and it stopped my leak as long as I didn't have the hose under pressure, soon as I put a nozzle on it, water just seeps out from under the tape.

I live in a mobile home and some idiot managed to drop the drain pipe for the tub below, and outside of the floor cavity. That bit of water will freeze in very cold weather and back up my tub so I wrapped it with this and it works like a charm. It's 1 1/2" pvc. It will work on anything as long as it is properly installed. It needs to be wrapped with insulation to hold the heat in. There's no thermostat with it so it's on all the time.

Yes. This cable is self regulating to make sure there are no hot spots/burn outs. The cover picture on our box shows foam insulation over the tape installed on a pipe.Hope this Helps Mike.

Maybe not. You aren't supposed to cross this stuff over on itself so if it's a short faucet as you say, then the 6' heat tape would be too long. Might want to try one of the quick-release faucet covers instead. They work well on our house spigots and our winters get to -15f at times.
