2" Sch 80 for Feed Pipe?

maxpower_454 · Post by **maxpower_454** » Tue. Dec. 29, 2015 4:52 pm

Has anyone ever tried sch 80 pipe for the feed tube? I can get a piece of sch 80 but no sch 40. The inside diameter is 1.94" vs 2.07" for sch 40. I'm thinking the pipe might wear a little more until it reaches the sch 40 ID but shouldn't cause a problem since the worm is about 1.5". I'm just speculating though. Anyone actually tried it?

I am pretty sure my pot auger tube is schedule 80. Will measure it tonight and get back to you.

Be the first to try,if you get too much crushing,you can always replace the pipe.You might get less crushing,because a lot of the crushing comes from areas where the coal bunches up,like under the coupler,and as the coal and worm enter the tube,and in worn tubes where there is room for bunching up.You will have a nice,tight,heavy duty tube.

All the pipes I put out are schedule 40. There is a big difference from 40 to 80. That tenth of an inch causes more stress/wear on the auger. While the pipe might be a good deal now, the decrease in auger life probably makes the schedule 40 a better deal long term.

Did you ever run one with a sch 80 pipe or are you just guessing about what effects a sch 80 pipe will have?

Guessing

It's not guessing to say that all else equal the smaller ID of Sch. 80 will restrict the throughput of coal. And I think Scottscoaled's point about stress/wear should be credited with being at least a well-educated guess, since the smaller available space is inevitably going to cause a tighter "fit" for larger pieces.

Guess I was wrong, mine appears to be schedule 40...although the pot tube has a slightly heavier wall than the bin tube. Strange.

Here is a picture of the pot tube.

This is a factory pipe and the one next to it is a stainless schedule 80. Noticeably thicker. The stainless is one I took in on trade. I would sell it for $50 plus shipping. I won't use it.

I think it would probably work with rice, but it might behave more like buck does with schedule 40 pipe.

I figured it was a guess. I'm looking for someone who has actually done it as I said in my first post. I agree with fif. The wear on the auger is always where the loosest fit is - the coupling and the pot. Im nog dead set on it but If I do it I'll post back with results. Unless someone else did it and they post in the meantime.

Btw, I only burn rice. It might work differently with buck

Sorry, I am not aware of anyone that has tried it. You can be the first.

Are you sure thsts not sch 80? Can you measure the wall thickness? Sch 80 is .22 sch 40 is .15

No, he is not the first. I had a short piece of black iron pipe for my first burn pot pipe. I used to get a lot of fines. I always thought it was the coal. After two years, I had to rebuild the pot because a couple plates broke. That meant new plates, auger and tube. I can't say for sure that it caused more fines running the thicker tube as I also was changing coals after that. I never did get that many fines again thinking back. Once again, guessing.
