Using 36" OD Pipe for Fire Ring???


So I picked up a 36" OD steel pipe that is about 3/8" thick and 24" tall this weekend for a fire pit liner

I'm going to line the outside of it with retaining wall blocks.

My question is do I need vent holes drilled into the steel liner? If so How many do you think I need?

No need for vent holes. There's nothing to vent. Many campgrounds use the outer portion of semi-truck split rims for fire rings. Never seen a vent hole in any of them.

Using 36" OD Pipe for Fire Ring???


When I lived in a small logging community on Vancouver island, if we needed a firering we would visit the HD shop and pick up the old wheel rims off the logging trucks. Because they were split rims they were the perfect size. It seemed like every backyard had one.

Since the depth of the ring could starve the fire of air, some devised some cleaver ideas. Setting the ring on a few large stones allowed air to rush in on the outside of the ring and up through the bottoms. If the ring was set in the ground some would bury a vent pipe( about 2-3" steel) out to an air source. I suppose you could even regulate the venting somehow to get those marshmallows golden brown.

OK, good point. Consider setting it up on bricks, (as mentioned above), and leaving some small gaps in your first courses of outer bricks... maybe no mortar on the ends in several places?

I would except I buried it about 10" below grade because the boss said it was too tall. I'm gonna have to drill or cut vents but I'm not sure how many and what size.

10 to 12 1/2" holes evenly spaced should do it. Half kind of low, and the other half 8" higher (every other one)

Ha. WHen I first read that I thought you wanted me to make holes that were between 10" and 12 1/2" evenly spaced!!!!

I see what you are saying now though.

Yeah I think I can make that happen. The good news is if I dont have enough I can always drill more!

8-3/4" holes about 4" off the bottom. keeps them from getting blocked by ash.

That is what Firebrick or rocks are for. If you want to have a metal shop weld some U loops of rebar on the bottom, to hold it up off the ground, you can do that.

Or just take a torch or Plasma cutter, and punch some holes in the rim at random areas around the bottom.

That what I done that many time I used propane/oxygen cutting torch for few holes but for big one I end up drag my old oil / oxygen cutting torch ( that is one of very wicked unit and once it going it hard to control if not aware how it ran and super hot as well .,, yeah noisey as well )

But really IMO the gaz cutting torch useally work the best plus quicker than use the drill.

Merci,
Marc

Those retaining wall blocks will not last long. Repeated exposure to high heat makes them crumble after awhile. If it were me, (and I do understand the boss is looking over your shoulder) I would cut around the circumference at an appropriate point in a fashion that would leave eight square teeth projecting down a few inches. Then bury a block where each leg will sit to keep it from sinking in the ground.
