How To Bend PVC

[@sknopster]

Works nicely with Salt and heat gun if you need to bend a section of pipe after assembly. (for water systems... it dissolves when line filled with water)

[@Xerock]

definitely gonna be using this technique for my projects

[@technicolorchristmas]

I'm an architect so when we built our house we did radiant heat concrete floors that were stained and polished. It's an acetone based dye that goes down in layers and has an acrylic sealer on top.

[@michaelpearce8661]

When I was in the electrical construction the way we did it was in heated antifreeze and placed it in a form to keep the bends uniform.

[@enkidusmurff]

Thanks! It worked great!!! I tried a heat gun and internal spring-kinked up, couldn't get that uniform heat like the sand supplies-thanks again for this post.

[@AnnoyingTheTriangle]

Nice with the radiant heat. When my house was being built I went in before they put in hardwoods and thought about just staining the concrete and going with that. Nice work. And thanks for doing this video. I am doing a project for my daughter for school and bending was the issue.

[@ZombieTex1]

Hit the outside with a blow dryer once you put the sand in so that it's heating from both inside and out. It should go a lot quicker.

[@seko6056]

You could also filled it up with normal (cold) temperature sand and heat the pipe up with small fire of a torch from outside, slowly not to burn the pipe. Pretty cool project thought that you've done.

[@technicolorchristmas]

Yes, that will work, however the pipe often "kinks". The sand supplies the same heat as steam or a heat gun, while maintaining the round shape of the pipe. If you want to prevent the distortion or flattening of the pipe, you have to have some medium on the inside to maintain it.

[@bernardmichel8750]

After various experiments I found out that bending pvc pipes with hot water was the best way !! This way , with sand , seems very good , but triky to use if trying to bend a 6 meters (19.6 feet)pipe !! With hot water applied from outside untill softening and then bending around a pre cut wooden form the work is made much easier !! But if you use flame it become brittle , and near useless since you cannot trust it anymore !! Now heat gun applied too hot or too long has the same effect that flame !!

[@Lovethempeas]

Do you stick the pipe in boiling water or just run it under a faucet?

[@victoracevedo1412]

Leaving comment here for response from Bernard

[@marthahunter3693]

[@Joani161]

Applied from outside means he probably poured it over the pipe.

[@richardhidenfelter533]

I thought your video on bending PVC pipe was great, it's very simple instructions for those with no experience to learn the basics and you need basics, to learn propper instructions before going into the quicker ways, thank you for sharing.

[@autotech7338]

Leave sand in pipe from one end to the other and tape both ends in place. then use a hot hair dryer and heat around the pipe where you want to bend it and the packed in sand will hold its form inside the pipe and you wont risk getting burned by this technique. Then un tape and dump out cold sand.

[@ISTOmaker]

Auto Tech That is the simple and efective way but the inside of the curve will not be visualy clean like this one.

[@mangbakoel8267]

Nice idea

[@MarkDaGardna]

This is definitely a cool method for bending and use of PVC pipe...Thanks!!!

[@westhurman2819]

Tried this today. Work great. Thanks for sharing.

[@uglytothebone5]

you just gave me a gr8 ideal on some light stans for my scroll saw table ect... mabe not as big of one so thanks

[@seamosserchin9024]

looks good man!

[@wotan711]

When my pool was built, I was astonished to see the Mexicans using a propane torch, sweeping it carefully back and forth along the PVC for a minute or so, then just grabbing one end of the pipe and jumping down into the pool pit and dragging the PVC behind them like a rubber hose! I couldn't believe how flexible it became. It was very fast and easy -- they do it all day long, so it has to be easy, fast, and effective. I've never tried it, but it sure looked easy.

[@kitainky]

Cool idea!! Your lights look good also!!

[@laokram]

lol yup... used my plumbers torch and a small dish. Takes some practice to get the temp just right. But works like a charm with small tools ;)

[@neatpleats11]

Great job. I have been seeing people heat the pvc from the outside. When the video began, I thought you were going to cook the sand in the aluminum pan using the burners. I guess its more important to use the oven to get the perfect temperature.

[@technicolorchristmas]

I've used a barbeque grill successfully several times. Works great.

[@Joewalshe38]

Thanks for video. I wonder would some of the very hot sand stick to the very hot and possibly partially melted PVC pipe.

[@JonnyDIY]

Thanks for the Tips. Great Vid. I thought you were gonna make Candy Canes out of them lol :)

[@charlietango186]

Just a thought, have you tried submerging the pipe ( where you want the bend) in boiling water, it has worked for me, or you could use a hot gun on the area that you want to bend, when it starts to go a bit floppy bend it to where you want it to be, then leave to cool down.

[@64298]

GREAT VIDEO! I need to bend a 4 inch wide strip of PVC into a half a 16 inch circle. Probably 1/4 inch thick PVC. Any good suggestions other than what you have shown?

[@technicolorchristmas]

I haven't tried it with pipe that large, I image there may be some kinking if you bend it too tightly. If you try it, let us know how it ends up!

[@bumstudios8817]

I haven't tried it to test my theory, but I wonder if you could just buy a flexible type metal tubing for sinks inside with heat gun on outside to keep the shape? if someone tries let me know.

[@technicolorchristmas]

+Chris Sproles There is a commercially available product that uses a spring on the inside to keep the shape, but it can still burn the outside of the pipe and it's expensive to purchase the tool.

[@stevenkeirstead6305]

Very interesting. I watched this looking for ways to bend nylon fuel line for a car repair. I was thinking of using sand but had not thought of heating the sand. Hmmm 🤔

[@jarvislacasse7161]

I like to see a video of you making a full circle

[@AnonymousUserDawg]

What's the largest diameter you've been successful with?

[@damianvan4285]

you can also leave the sand in the pipe and use a heat gun, bend as needed. The sand will keep the bend from allowing the pipe to collapse at the bend

[@juniorlewis9173]

Very good tutorial. I appreciate your help. Thanks for sharing with the world.

[@GDarkGoombaG]

How can I stretch PVC to form a constriction, like in a de Laval nozzle?

[@axelec]

Why use the oven when you have the cook top. It is a lot less time consuming and so much quicker. Set up two batches of sand so you do not have to wait for the second heat up.

[@justanotherwarrobotschanne5774]

a quick and dirty method for short sections is to microwave it with a glass of water. do not microwave if it has glue or any other impurities on it. Only works for small radius bends. dip in cold water to set.

[@Subeffulgent]

great work!

[@featherfanatics9793]

That looks like it could be used as a small aquarium siphon! And the baked sand could be substrate!

[@gizmothewytchdoktor1049]

this also works with metal tubing and a fire wrench. :-)

[@technicolorchristmas]

I've never tried it but I don't think it will work. You really need something that will "hold" the heat and the granular make up of the sand does that. It also helps get it out after you're finished bending and the pipe has cooled. I'd stick with sand, a small bag is very inexpensive at most big box stores.

[@Satchmoeddie]

Glycol hot benders were great, but the EPA frowned on glycol spills. We use the Greenlee "hotbox" 1/2-4" or "hot blanket" 1/2-2". Heat guns will do up to about 1 1/4". Propane torch 1 1/2", & weed burners will do 2" with patience and much care. Scorching the pipe ruins it. Hot sand is a great way to get even heating. Wear gloves, & don't kink the pipe. Use wet rags to cool pipe when it is shaped nicely. No ovens on a job site. Heat pipe evenly slowly carefully, & bend. Too hot = too soft.

[@deanings]

This can be done by channeling steam from a kettle through the pipe until the pipe shows signs of sagging and then bend to shape.

[@alfredomarquez9777]

Yes. But with steam it is easy to get burned, as it is hard to see! Hot sand seems safer and more practical.

[@HKCRemodel]

Very useful info on bending plastic pipes.

[@breeze344]

will this technique work on 11/2" sch 40 pvc as well??

[@michaelhenwood4046]

I can almost picture some of that hot sand hitting his bare feet(ouch,ouch,ouch).

[@mikejohnson4723]

Either his feet, or his other hand that is holding the pvc tubing. Double ouch, lol

[@sergiov2236]

That looks useful for a homemade snorkel.... and what about heating up the sand in a frying pan on the stovetop?

[@laokram]

Well done :)

[@KennethElstonBAK]

That's a lot of work... But, I think that it using this method along wit ha heat gun would woke prefect!! Not I need to find a reason to bend some PVC just to give it a try. Question: Does the sand melt or pit the inside of the PVC by sitting on it heated? Thanks for the vid

[@algesbrek8837]

would the sand keep the pipe from kinking ?

[@MrWerewoofie]

Do I have to use sand, or can I substitute it with dirt?

[@nastypupp]

good idea, seems easy too. thanks! my imagination is about to kick in. lol

[@williamstewart6516]

Very cool , Thanks>

[@technicolorchristmas]

You can buy play sand in a 2lb bag at most big box home improvement centers.

[@MrFury4]

wow you have a nice house I wish mine was like that

[@thomasbranard6382]

Thank you great job

[@levicoates2814]

The sand is a great idea dude but why the oven idk why when you can use a heat gun to bend the pipe while the sand is in the pipe to hold the shape...thats where i thought this video was going

[@technicolorchristmas]

I've heard that just heating it on a sheet in the oven will work too. Try it and let us know, it's the hazards and rewards of DIY!

[@technicolorchristmas]

Steve, you must have missed it in the video and the numerous comments. The floor is stained and polished concrete. No problem with heat. ;)

[@DespiseStupidity]

I didn't think she was mad as much as she was getting a little kick making fun at your expense! "On the floor?"

[@livefreeordie4850]

Awesome!

[@VerasFree]

A+ Stain PVC with clear acetone & clothing dye, or clear PVC glue & dye.

[@rwegman2012]

good vid could be easy make for garden trellis. again thanks

[@snakeclaw]

nice vid. fyi....you can heat that sand to 550 in mere seconds using a propane or map gas torch.

[@technicolorchristmas]

+snakeclaw I know, that's the way I do it in the follow up video. kzbin.info/www/bejne/fH2wandpq5aAr6s&lc=z12jwfepjrnuxlqeu23etrfjurashre5p04

[@AlCatrraz]

For some reason...... FUNNEL CAKE comes to mind.... Thanks for the idea...

[@frank0067]

interesting , now that's using your head man ! i got another idea - compressed steam with a mold. this also may reduce pressure rating of the pipe, as long as you don't need to use it for its rated pressure should be ok.

[@tahitibob96]

frank0067 m

[@MrMorbo420]

use potting vermiculite to insulate the pipe and the sand will not cool as fast. just FYI use knowledge as desired.

[@technicolorchristmas]

+Jeremy Fleming great idea, thanks for the tip!

[@How2Wrench]

Fun and useful! Hope you find something useful on my channel. I'm adding this video to my "Make your own tools" playlist!

[@MrJarjau]

After placing sand inside the tube, I suggest dipping the tube into boiling water to make it easier to fold. What about the suggestion? Sorry my bad english. Congratulations from Brazil!!

[@technicolorchristmas]

This method will work, however, you need a large pot and a lot of water to do a larger section of pipe. Heating the sand allows you to bend the whole pipe at once and there's really no limit to the length.

[@treeman911]

What color concrete stain did you use on your floor? Rustic?

[@Iamlearningtolove]

I would like to know too! 😁

[@technicolorchristmas]

There is some slight residual sand inside but it usually washes out with a quick blast of air or water. If it's sticking a lot your sand is TOO Hot. ;)

[@supersayianchris]

you are a pvc master

[@gilbertos1966]

Não entendi nada do que você falou . Mais aprendi muito bem parabéns pelo vídeo.(era o que eu estava procurando)

[@technicolorchristmas]

Got a dozen of em now~!

[@technicolorchristmas]

I don't notice any fumes, you can always do it in a garage or move it outside once you are ready to pour the sand!

[@AllAlaskan907]

You can get a 50 lb bag at Lowes or home depot for under $10. Regular Play sand or pool filter sand (less dusty) .

[@TheFranklinman]

AllAlaskan907

[@TheCalethompson]

If you don't have a heat gun. I'd say this is a decent way to bend but I'd say more of a hassle compared to using other alternatives but still a good video.

[@tomthumb6307]

If you don't have one you just have to buy one! With all the plastic goodies today a little heat is almost necessary for removal and reassembly . No need for fancy dial temp models, simply adjust using distance from the heated object. They save bundles of cash on broken items, especially if they are old or sun hardened. I use mine at least weekly for something

[@divyajnana]

Great trick, thanks

[@nareshlaxamanpatil2050]

really very good idea thanks

[@mmichaeldonavon]

Didn't you love it when his wife said: "all over the floor?" (when he was pouring the hot sand into the tube). Ha, ha, ha, we guys want to get "the job done"; she wants to insure that no sand gets on the floor! ha, ha, ha, ha,

[@ALthePAL01]

You have to use sand. Dirt won't work because it won't hold the heat. Pretty much any sand would work. You can get it at a pond, beach, or even a store like Toys R Us that sells sand for sand boxes. You can also get sand at landscaping companies or nurseries.

[@edilbertobeauchamp8668]

Alan Holyoak. Muy costoso tu método para doblar un tubo pvc. Demasiado tiempo para doblarlo

[@adelliott118]

Ok, And YOUR WIFE is ok doing that (or any projects) in her beautiful Kitchen... Mine would kick me and my project outside. LOL

[@jolllyroger1]

And Noneya if she don't like it she can pound sand and find another man to support her sorry ass... I'm so sick of Sissies that say your wife lets you... Any one says that has no testicles

[@waltergettys6718]

And Noneya

[@donaldanderson7410]

jolllyroger1 so you cook, clean, and sew? You are the wife and the husband. You must live on your own because you have no social skills. It’s probably best that way.

[@cruz47144]

Great video but it's hard to find ovens on a construction site.

[@CougarHouseGarage]

Your videos are always so engaging :), The subject for your videos are on point :), This video of yours had me glued to the screen:), What camera do you use to shoot your episodes?, What microphone do use?

[@VerifyVeracity]

Pre-heat the pipe then pore the sand into it, then you'll only need to do it once.

[@22Nimily]

Does this method produce the harmful fumes that using a torch or heat gun would? I want to do this in my kitchen to make a bird perch.

[@BrokenRRT]

Sand such as silica or mason type works better.

[@refan742]

from your idea i got to fill the pipe by sand and then you can use heat gun

[@therider3939]

can we use Hot water in the sand

[@RedactedNPC]

What if you don't have sand?

[@vinodsahai648]

Can I hot water also??

[@edisonedwardantony]

good

[@oozger1]

but sand in pipe than heating the pipe out side

[@Ricangal]

Why'd you get your beautiful floor? The lesson was excellent BTW.

[@technicolorchristmas]

Nope, concrete floors, it sweeps right up!

[@szaki]

Do I have to wear a shoe to bend the pipe? (o:

[@juventinoramirez2715]

szaki yes, shoes, safety glasses and gloves on both hands.

[@seko6056]

probably yeah!!!

[@mikejohnson4723]

Be safe than sorry.
