Hauling pipe

2-3/8 will tie down good. I would guess 4ft stakes would be good at 3 or 4 foot intervals. You would only need dunnage under the bottom layer unless they want it otherwise. I believe they come in 30ft joints, approximately 6.8lb/ft, so about 215lb per joint. Maybe 205 joints to a load? I'm not a pipe hauler, but have been around oilfield stuff for a long time

 

Yup, just stack it in layers, and keep yer straps n chains tight

 

I've hauled oilfield pipe on several occasions. If it's going to be used, they won't let you chain it, but being as it's for a buddy, it may not matter. If so, I'd stack it all together (some folks don't like doing it that way) in what they call "pyramid" style, gut-wrap front and rear, then chain and/or strap down. The problem with pipe is that there is no good way to prevent forward movement if you happen to be involved in a wreck or something. Build a bulkhead if you can, but I don't know how much it will help. Just keep the load tightly secured. Stop and check it a few times as it may settle.

As for stakes, we always just used four big ones. Two on each side of the trailer.

 

Our pipe stakes were made to fit the specific trailer, but you can make generic stakes from some C-channel that fits into your stake pockets, with a piece of rebar welded across it to keep it from falling thru.

 

You need to figure out pipe specs,
2 3/8 pipe x 1/4" wall thickness weighs appx 7.5lb per foot or 240 per piece at 32ft.
334 joints x240lbs= 80,160lbs on your trailer!

 

4 pipe stakes, and they are not required maybe only if the shipper or receiver require them. Good idea to have pipe chocks also.
