This is a brief tutorial on how to welding plastic pipe. I show how I weld high density polyethylene sewer pipe using a heat gun with adapter, and sawsall. Please note: This will not work on pvc pipe.
Thank you for the feedback. Oh, and by the way, here is a link to the one video you uploaded, just to show folks how a video is supposed to be done. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-0ntwKkoEu0g.html
You are very resourceful and creative to come up with a 20 degree adapter for your pipe. You also make cutting and "welding" it look easy. Thanks for the money saving idea!
Very helpful, thank you. I don't know if you reply to old videos, but am wondering if you could use the same process with cut up bits as weld material? I want to weld a 3/4" hdpe water line to a 36" hdpe culvert which will be a well casing. Thinking it might be more effective than trying a strip.
This is a man after my own heart, “so to speak” ! Moment by moment, inch by inch, thought by thought... and no special-order Tools. One suggestion from a guy who attends the school of hard knocks, where they never issue diplomas: PLEASE cut the welding filler with a safer method! I have the scars...
Just what I needed to see! Just fished out a 36”x20’ long pipe that got away from my neighbor in a pond. Said I can have it if I got it. Well I got it and it looks like he sent some excavator teeth into it in a few-spots. Glad to know I’ll be able to fix it. Any suggestions on making an attachment like that without a milking machine?
Arnold, thanks for the video. What are your thoughts on using HDPE culverts for dock floats? and do you think welding end caps onto each end would be strong enough and sealed enough to never leak or crack?Thank you.
I think that's an excellent idea, as long as the welds are sound. You could test them by drilling a tiny hole in the pipe body and pressurizing with a very low psi, like 1 or 2 psi, and checking around the weld with soapy water. I would put a vent tube in that hole and point the tube down to prevent rain from getting in. The vent would prevent end cap collapse or rupture when temps change. Keep the psi low when testing, because even at 1 or 2 psi, you're going to have 75 to 150 pounds pushing outward on the end caps. Let me know if need to know the size of pipe needed for the gross weight, and size of your dock. I can show you the calculations to use.
Do you think it would be possible to heat weld a 60 inch diameter HDPE pipe together using this method? And have it be waterproof and structurally sound enough to move a 20 foot pipe
I just used some old aluminum I had laying around, and a piece of chrome moly tubing. I turned it on the lathe, and used set screws to hold it together.
Get yourself a stick and sand the end round to use it to do what you're doing with your gloved fingers and thumb. should make the process a whole lot more pleasant.
Arnold this appears to be the same material as ABS sewer pipe that's used in homes. they have a chemical process, it's a two-part process of chemicals that glue everything together. you may find it easier to use that glue than the heat gun as it melts the plastic chemically and bonds it together chemically. otherwise this is a wonderful video on a different method on how to do this as well.
Maybe with a large enough heat source like a space heater and box built around the area to be bent. I think it would be tricky to implement though on large diameter pipes.
@@ArnoldsDesign Thanks for your answer. It woud be for 8" corrugated pipe. I'd like to ask you another question: Between HDPE and PVC (both of them corrugated) which is easier to get bend? Sorry for my english level.
@@moiseslobo No problem. I've bent smaller schedule 40 pvc water pipes before, up to 2", and it wasn't too bad. I don't know how much harder an 8" double wall pipe would be. Pvc gives off some nasty fumes when it gets hot, so that's something to keep in mind.
this is NOT sewer pipe. it is stormwater and irrigation pipe. your welding skills are good but your commentary is wrong. if it is hot enough to bend it is NOT hot enoughbto weld. the surface on both parts MUST be tacky or melted to bond. on thick material like you are using it gakes a long time to get to that stage
