Snow Attachments ABS Plastic Pipe Snow Blade Edge

I worked in a plumbing supply store, and they generally call PVC pipe "sch 40" even though the scheduale wall thickness system applies to any pipe using the nominal pipe measuring system EG: ERW black steel pipe uses the nominal pipe system as well.

ABS is the black DWV piping (drain waste vent) used for sewer. PVC is white used for potable water supply.

I havent seen HDPE piping but that would be the cats meow. We put sheets of that on the bottom of river boats here to bank off of rocks and its tough stuff!

I've tried 1 1/2", 2" and 3"

A pattern has formed. Obviously, the bigger the diameter, the greater the "float" effect. It's a no brainer. The float factor is your friend, if you are gouging grass, digging up gravel, etc. YMMV.

That said, you can over do it. Once the ground begins to freeze up, you may wish to lower the diameter for a smaller "edge" and more cutting, less float.
You may also wish to remove it altogether, at that point.

If you want HDPE go look in the irrigation section of Home Depot, Lowes, etc. They sell it in rolls, usually 100' lengths. They usually have various thicknesses of material rated by the service pressure they are intended to carry. Coming in a roll it may be hard to split and place on a blade.

Yes you are correct, the stuff that I have is 30 years old, and it is still wants to stay coiled up in a 6 foot diameter roll. A 4 1/2" grinder with a abrasive cut off blade works good for splitting it as does a 5 1/2" circular saw. Once you pound it on the blade edge though it will stay straight

Schedule XX is a measurement of thickness/gauge basically. Ask a pro, which I am not.

These different plastics vary widely in their abilities and characteristics, strengths, resiliency, impact, shatter temperatures, etc. None of these products were designed for what we are doing with them.

That said, PVC is pretty brittle, ABS much, much less so, and HDPE is space-age stuff, but I cannot get my hands on any out here in the sticks!

I suppose Kevlar, if made into such a pipe would be as strong or stronger than steel itself.

HDPE ( High density polyethelene ) isn't space age stuff. It has been around a long time and it is cheap. It is very impact resistant. I don't think you could break it with a hammer if you tried. It is also soft as compared to PVC or ABS. You can leave a mark in it with your thumb nail. But you can hit it as hard as you can with a hammer and it will just bounce off! Since it is relatively soft it will probably wear at a faster rate than ABS.

Steve,

OK, it was first made into pipe in 1955, while Sputnik launched the space age in 1957, so HDPE technically pre-dates the space age by two years. Mea Culpa!

I'm quite happy, so far, with my ABS.

How much snow did you guys get down that way?

It is hard to tell it keeps blowing around in piles, I would think it is only about 6 inches if you can find a level spot! But it is blown in hard enough to walk on the 2 foot drifts without sinking in....

Lowe's and the other box stores around here carry ABS. Not nearly the selection as PVC though. I looked at some the other day and noticed the price for ABS was about 30 - 50% higher than PVC. That could be due to old stock that reflects the higher oil prices from last year. I have a partial paved drive, but mostly gravel. I'm curious if it would clear a concrete drive or make a mess.

ABS isn't all that pricey. A 10' stick of 1 1/2" is $3.93 at Lowes.
Check this:
Silver-Line Plastics at Lowe's: 1-1/2" x 10' ABS Cellular Core Pipe

What I cannot tell is whether this piece is comparable to what I got at ACE today.

What is the difference between HDPE and schedule 80? I've called three plumbing supply houses and they seem clueless when I say "High Density Polyethyline" but admit that they have schedule 80. What is the difference?

As you have noted, HDPE is the type of material. As another has noted, Schedule 80 refers to the pipe's wall thickness regardless of material. The most common schedules in use are 40, then 80, then 160. There are Schedules 5, 10, 20; but they are rarely used regardless of material type and hence tend to cost more because they aren't readily available. In steel pipe there are XS (eXtra Strong) and XXS (double eXtra Strong, eXtra eXtra Strong) too. The Schedule 160 is referring to steel. Who, why and when created the schedule numbers is unknown to me. That's a sad commentary on the plumbing supply houses' staff if they don't know the difference between HDPE and Schedule 80.

Interesting test results on the ABS pipe, I may develop a whole new respect for the stuff. I think it's the Butadiene in the plastic that gives it its ductility. When I was a model maker as a teen, I used butadiene tubing sold by Plastruct. That stuff was a nuisance to use because it was so soft compared to Acrylic and Styrene.
