    Default HDPE Arches

    I'm starting a new thread for HDPE arches rather then keep using the PEX Arches thread. I'll try to keep the first post up to date with the latest information on building arches from HDPE tubing.

    First the basics:
    • The HDPE tubing used for these arches is made by Hudson Extrusions out of Hudson, Ohio.
    • You can buy the tubing from McMaster-Carr.
    • The recommended size tubing is 2" OD, 1.75" ID.
    • The recommended pixel strip, 5m DC12V 60leds/m 20pcs ws2811 ic/meter(20pixels) led digital strip, comes from Ray's Store. They come in two versions, waterproof and non-waterproof. I recommend the non-waterproof as they will sit flatter in the HDPE tube and cast less of a shadow.


    Mounting:

    Finding a good way to mount them has been a bit of a challenge.

    Method #1:

    One thing I found is that standard 1.5" EMT you can get at Home Depot will just slide into the tube. When used it makes the section rock solid and in fact you could weld the EMT to a plate and stake the plate into the ground. You need to allow for a waterproof cable exit if you go this route. This was how I had originally planned to do them and in fact I might still go that route however I found another way using plumbing parts.

    Method #2:

    I found that a Nibco 2" Trap adapter will make a solid connection to the 2" HDPE. There are two version, one that fits the pipe and one that fits into a fi

    Which one you use depends on how you build the mount but the one that fits into a fitting will normally be the better choice. Only problem is that HD does not carry that part.

    How do you use these? There are several different ways. You could use Wyes, directly stake pipe in to the ground or onto a flange. I'm thinking about using double Wyes and single Wyes.

    Why did I chose one with a top entry? So I can run a straight up pole as a fire stick/north pole. If you use a 3-3-2-2 or 3-3-2 Wye you can use a adapter and use the Tine tubes as a vertical pole. Now you see why I say to use the Trap adapter than fits into a fitting. It makes for a cleaner connection into the Wye.

    Now 3" pipe is very large to push into the ground so I'd put an adapter in the bottom of the why to reduce to say a 3/4" or 1" pipe. Another way is to use a closet flange upside down and stake it to the ground.

    Although I've listed the ABS versions, that's what we use on the West coast, you can get the same fittings in PVC for those on the East coast.

    Ok, that's the first cut at how to build. We'll add more later.

    Have fun.

    Its not the $2, it's getting the strips closer to the tube so less shadows. I'm still working on the way to seal the ends of the HDPE tubes. Once that's done there is no reason for the waterproof strips.

    From the test vids you posted in the other thread, it looks like you're using the white HDPE. Is this correct? My arches are done this year with the PEX and CCP strings I have, but I haven't lit them up yet. Just looking toward next year and using strips insted of pixel nodes if I dont like the ones I have for this year

    Here is Ralph's video of HDPE Arches using CCP pixels

    http://www.youtube.com/watch?feature...&v=kIyrbqAj_sY



    My HDPE 2" OD arches are made using 6809 5m flex strips 150 pixels 3 per pixel. 2.5 meter in each 8' tube. The strip is on the bottom of the tube facing up as Timon suggested. I'm ordering the 60/20 5 meter strips for 5 arches.

    BTW, the tubing should just fit inside standard 2" EMT, well the specs say so but I need to go to HD and double check.

    I've got a design on the drawing board for a complete set bracket for both the ends and mid spans. The mounts will be on pivots so the angle of the arch can be adjusted. I was also going to add a mount in the middle for a vertical tint tube.

    I've also found a way to easily seal the ends on the arch so they stay waterproof. McMaster-Carr has HDPE rod which fits the inside of the tubing. Add a waterproof gland and you have a sealed tube.

    Early this week I'm going to see what it costs to weld them up.

    Hey guys, First I want to Thank Timon and Tmcteer and Ron boyd you guys are just fantastic, and for there great posts, I would not have gotten anywhere with my arches if it wasn't for them. so thanks guys. and Thanks Tom for mentioning my video, that was my short video,I am learning how to post videos too, you'd think after 10 years of doing this stuff i'd know how to post video's lol well I don't, but learning I made a full 5 min video on the arches as well, I think its much better then the short one, only thing was i did not have my notes with me at the time and stated a couple of facts wrong, so please excuse the name of the hdpe tubing that i said in the video as pex pipe, my bad. heres the full video link. I hope this adds to the useful help everyone looks for. Fyi, I made my arches with ccp's which look like c6 bulbs, and as nice are they are, they are not made for making arches with so i have already ordered 3 sets of 12v 5 meter 60/60 pixel strips from ray wo. when i get those baby's i will fire them up and show you what they look like compared to the ccp pixels arches.

    Ralph, Did you take any video from a distance? The reason I ask is, Andy Harrison did his last year with 2811 Pixel nodes and it looked like a solid smooth transition from a distance. Can you take some vids from a little further away?
