soil pipe as a discharge chute from a 30tph elevator

I am in the process of changing the way I handle seed peas, as augers / sucker blowers etc are to hard on them resulting in rejections.

I need to fill two silos side by side. I have an vertical box elevator (chain and paddle) which I can site next to the silos. The height is sufficient whereby I can get a 35 degree fall from the top of the elevator to the silo, so the peas should run under gravity

I am thinking of using large diameter plastic soil pipe (160mm instead of the normal 110) as discharge chutes. Quite a practical solution I thought, as it doesnt rust, its very free flowing and lots of sockets and bends etc are available off the shelf

Before I go ahead, is there an alternative do you think? Also is 160mm (ID) sufficient for 30tph at around 35 degree?

Will work ok, but will only last so long before plastic wears through

The right type of plastic wouldn’t wear through.

I'm sure I have seen plastic used before in grain handling plant. It is cheap so worth a try?

Plastic is often harder than tin.
Only prob I forsee is UV degradation. However it seems pvc pipe is better than abs pipe. Whether one is more wear resistant than the other i don’t know

I'm sure PVC plastic is pretty resistant to UV radiation from memory? Wrap it in reflective aluminium tape?

My dad bought a mains water pipe for cow troughs in feeders. 20 years on they were completely still as new.

PVC is used extensively here as down water pipes on buildings & also more recently as guttering instead of metal.
All the down water pipes on my house are unpainted, white PVC.
Our UV levels are probably a bit higher than yours . . .

The bigger problem may be the actual weight of the grain inside the pipe & the length of your span. Might need support if the weight is too much ?

Make sure you use grey downpipe rather than brown/orange soil pipe as it’s uv stabilised

Used it here in the past. No problem at all.
