Yes, they run separate. Like electricity being run in Parelle instead of series. Or, DC as opposed to AC. My point is they both use 6' Iron. The snowmakers know it will break, butt if you stay ahead of it....

In New England there are many different sizes and only a select few (newer) feed lines are ductile iron. The remaining 99.99% of pipe out there is carbon steel. Also some old aluminum victaulic in the wild too.

That literally doesn't happen anywhere. Water and air are always separate. Perhaps if it is a dedicated fan gun run, there would only be a water pipe since modern fan guns have onboard air compressors.
Unless they just use water, Tremblant has single feed lines down the Versant Solei side to tower stick guns. Only place I have ever seen that setup, and the guns lining those trails only have a single hose connection on their bases.

Yep, and in which case there is 3 Phase to every location in lieu of air. Absolutely asinine to do for a place with an established air plant IMHO.

Maybe just keep your eyes closed. It would be just as useful

I’m lost... how are the names “Hornet” and “Eclipse” Native American?!?

And all the other trails are named for flowers.
Okay, let's name ski trails after flowers. :unsure: I can see this happening Vermont, butt not in New Hampshire. There's a good poll in here somewhere - not.

What's your favorite trail named after a ....:)

I know of two places with plastic airlines, though I wasn't on the install in either place and don't know the exact details. Canaan Valley had one trail, Holiday Mtn is putting some in this year.

The vast majority of snowmaking pipe is steel pipe. There's some ductile iron and some coated pipe systems but also a lot of ex-oil and gas pipe bought lightly used.

I'm at a "power at every gun" place but we don't have a hill air plant - all onboard compressors or airless SMI 320s.

If someone invented an air hose that didn't rust or break that would be nice. (At a better price)
By power at every gun are you talking fans?
Airless seems to be another solution, butt you have to run higher pressure on the water (guessing).
And the beat goes on...

Airless kinda died out because the output sucked and yes the required water pressure is astronomical.

Also I'd say the Impulse had something to do it too lol.

Actually the 320 works by mechanical atomization and doesn't mind low water pressure. It's a truly airless snowgun.

We have about 20 of those and 30 newer fan guns.

You can run some newer low E sticks airless, but basically nobody builds airless only sticks for the North American market these days. HKD external mix towers would run airless in severe cold, but the internal mix designs could have issues. I think Ratniks supports airless operation on some of their low E models?

What is the benefit of ductile iron? Greek Peak always puts that in when the replace pipe.

Less than 10°F wetbulb both HKD towers and Ratnik low E towers don’t need air as the fine mist of water can freeze before reaching the ground in those temps. Has nothing to do with a radiator. And the snow gun won’t break in those conditions.

Totally, Tenney’s back and it’s looking good! It reminds me a bit of Magic with those steep, narrow trails and not a ton of snowmaking. I’ve been there a few times, and it’s got that local charm that’s hard to beat. The $40 lift tickets are a great deal, and the season pass price is solid too. If you’re up for supporting a smaller spot, it’s definitely worth it.

Ductile lasts longer. Doesn't corrode like steel. Has a lower friction value (friction coefficient) vs steel as well. But more expensive which is why in New England you just see it on big (underground) feeds.

Doug is doing the on hill stuff but the owners have a company from MA doing the pump and booster stations. I don't think they've ever done snowmaking. We'll see how that goes.

I just toured a ski area pump station done by a golf pump station company, and the operator was very happy with it. That was part of a project that included 80-odd holes of golf irrigation, so the golf guys had a foot in the door.

Here's hoping Tenney gets the same experience.

Where did the HPDE come back into the conversation? I know a couple places using it or similar on the air side only, that'll never see 600+ psi. Maybe 120 psi.
