Any ideas what to do with network tubings?

I got my hands on hundreds of meters of network tubings last year, thinking I could use it for SOMETHING (have ten times more than on the picture). But I don't get any ideas!!! :-( Should I melt it? Into what? Should I build a statue? How? Could I make art of the tubing? What kind? I'm completly dry, pleeeaaase help... Would appriciate if you would send pictures to your ideas! :-) Thanks!

You mean just the outer tube with no wires or anything in it??
How did you get them??? LOL

I know there are at least two types out in the market.
First one is quite hard and only requires a scratch with a knife to break it open.
Second one is a bit softer and flexible and actually requires a full cut to tear it apart.
Anything with positive pressure and and avoiding kinks will work them to about 20psi of pressure, in hot areas it might be less.
Problem with the first is that is becomes really hard and brittle in frosty conditions.
Here a scratch can be enough to make it fail under pressure.
Recycling is a bitch for both as the melting requires precise temp control and preferably the absence of oxygen.

You can glue it quite good with contact glue or by heat melting it.
So you could make a lot of garden sprinklers or water splashing toys for the kids...
Since it is quite flexible under the right conditions you could use it to make a big float for your favourite lake, just heat the ends or fill them with hot glue and get them together like a mat with many layers....
Sound proofing is another idea that might work.
Just mount in rows and the rounded surfaces will disperse the sound without adding too much to the wall.
And since you have different colors you could them in length to create a big picture sound proofing....
Shall I go on? ;)

PLEASE, GO ON Downunder35m!!!

Great answer, fuller than I ever imagined!!! :-) I asked to get them when my community installed ground based broadband last year, the company installing didn't use the entire reels. I'm not usually the beggar-kind-of-guy, but here I thought I could do fantastical things. NOT! Hehe :-) I have good imagination, normally, but not with stuff like theese it seems.

Hey, I found out exactly the type: The "tubings" are actually called "ducts", and the "brand name" is Microduct. There was a lable on one of the reels, thankfully :-) Here's some picture, and a Wikipedia-link.

Bending them, I suppose they are semi-flexible, as explained on the Wiki-page. No reference though of what material they are made of (considering melting or heating).


HPDE can't really be glued with anything so you might have to revert to contact glue for artwork and similar.
A simple stapler might do the trick too ;)

Ever wanted you own wind tunnel or water tunnel for experiments involving turbulences and similar??
Cut the tubing into about 10-15cm long pieces and place into a frame of your desired size.
Looks then like a honeycomb with round holes.
This will cause air from a fan or water from a pump to be aligned and form a very straight and turbulence free stream.

Since the material is quite dense you could also try to use it for communication ;)
Like a stethoscope the sound sound will travel through the tube.
Use an in ear headphone speaker on one end an an elecret microphone on the other and you get wireless communication without the deadly risk of producing radio waves LOL
Oh, for two way communication you need to double the system but with speaker and microphone at the other ends.

I had heard rumor the internet was made of tubes,

but I had never actually seen pictures of these tubes, until today.

The producers home page says the ducts are made from HDPE; High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum

I suspected something like this based on the shiny image.
Definately not the standard stuff that keeps network cables (cat5,6) together.
More heavy duty for underground use.
But you can recycle it, in fact I like the stuff for machining new stuff that broke.
At home it can be tricky though without the right tools.
@ around 220°C it will start to melt or better go soft, a bit more temp and it becomes sticky and can be pressed together or extruded.
Problem is that the stuff is a good insulator as well and it does not like oxygen when when heated too much as it goes brittle.
Forgot what oil I used but I went to the supermarket and checked what temp frying oils will tolerate and grabbed the one with the highest temp LOL
Put in a pot with a smaller can inside and you are good to try.
Requires a good thermometer though and never leave it alone!!!
If the oil smokes before you can press the material in the can to a solid lump you need a different oil to prevent a flash burn!
Best option would be an extruder with a good temp controller, maybe as simple as an old meatgrinder with enough heating wire around it....
