thickest 2x2 square tube to fit receiver hitch

[SCWOOD]

I found a piece of 2x2 3/16 thick wall at work.the thickness measures .180.I think this will work with my tractor. I bought Nortrac subsoiler from Northern tool for $109 with coupon.I am going to add something were the top link would go.I will post pics when I get it done.The steel I am getting is free.Left over pieces.

That is just backward, pipe OD doesn't change with thickness- schedule 40 pipe is same OD as schedule 160- the inside hole just gets smaller and smaller. Piping OD is not true sizing as example 2" pipe is 2 3/8" OD regardless of thickness.
Tubing is ID measurement, the OD changes as the tubing gets thicker. This is same for round tubing as square tubing.Edit: not that most folks will be dealing with larger sizes but I thought I should clarify. After pipe reaches 14"nominal size the OD is the actual size of the pipe so 14"pipe OD is 14" and this is true for all sizes above 14". The thicker the pipe is then the smaller the ID becomes.

You were doing so good, until this part. The two pieces of square tubing in the pic are considered 1". Obviously they are different thickness walls. Obviously the outside measurement is the same.

I've bought a lot of it and never known the size just went to a machine shop and asked for some receiver tubing. May have to know next time I go as my truck has a 2" tube and requires a sleeve for what use to be normal.

Common receiver tubes are 1 1/4, 2, and 2 1/2 inches. This is the outside measurement of what fits INTO it. Or approximately the inside measurement. The fit is sometimes sloppy. Receiver tube may be non-standard on the outside dimensions.

Another difference is that the inside seam burr is removed from receiver tube.

Let's clear this up once and for all, since both Gary and I posted information that isn't totally correct. Though it sounds like the OP has moved on, perhaps this will be useful to someone doing a search...

As Gary points out, "Pipe" (which is round) is specified by a nominal size (ie 2") and a "Schedule" of 10, 40, 80, or 160 that determines wall thickness. The OD is fixed, at a size larger than nominal, with ID of Schedule 40 pipe being roughly the nominal. For example, 2" Pipe has an OD of 2.375" regardless of what Schedule it is, and the ID of 2" Sch 40 pipe is very close to 2". (I believe I suggested that the ID was always 2" above, and that's not correct.)

Round "Mechanical Tubing" (ex DOM, CDS, ERW) is specified by a true OD and either wall thickness or ID, depending on type. (DOM is OD/ID, other tubing varieties are OD/wall thickness.) These dimensions are tightly controlled by ASTM A513 for DOM, and A519 for other types. Thus 2" OD round "Tubing" is always exactly 2" OD.

Square and Rectangle "Mechanical Tubing", is generally governed by ASTM A513 or A500, depending on size. As with round "tubing", the measurements given are exact outside dimensions. IE, 2"x2" square tubing is exactly 2" outside regardless of whether it's 16ga or 1/4" wall.

I believe Gary may have been thinking about Conduit rather than Mechanical Tubing when he made the comment above that tubing is sized by ID for round and square... I believe that is true for round conduit, but I'm not sure I've ever seen square conduit, and I've not seen any choice in the wall thickness of conduit either... I guess I'm not sure what he was thinking of, but the above is true, and can be verified.

Thus concludes today's lesson for us all.

What does schedule actually mean, is it a measure of pressure ratings, potential flow rate, wall thickness...Example does 2" sch 40 PVC pipe have anything in common with 2" sch 40 black iron pipe other than the OD. would they have the same wall thickness perhaps?

Schedule is thickness.

Yep. It's that inside seam that is hard to deal with.

Found that out when I made my weight box with a hitch receiver. Took a little filing and knocking off high spots on my drawbar, but it fits nicely. If I had to do it again I'd try to find some of that metric tube.

\I learned that the receiver (female) part is METRIC tubing.
Local steel supplier carries it.
Also it has no weld seem on inside.

Perhaps in Canada it is.

In the US, receiver tubing is usually .238" wall 2.5" square tubing with the flash removed. I believe it is actually welded with the flash on the outside, and is then ground off by machine since that's easy. My supplier charges $180 for a 24' stick of it, obviously much cheaper when ordering a quantity and/or with other stuff.

I've found that for most applications, it's far easier to buy pre-made receiver stock with the reinforcement ring and pin holes already done, at least for most projects. I'd really only buy the bulk tube if I wanted to make something that telescoped.

I used to replace the tongue on a small, 40" x 48", trailer that I use around here but not on road anymore. The tongues on those small trailers are typically attached from the center of the trailer, forward. I made the new tubing extend from the front of the original tongue length to the rear edge of the trailer and it makes the trailer much stronger. I use the trailer with flat hitches or ball hitches front or back and can daisy chain it as the lead trailer pulling another behind it, or use it as the second trailer. It's become a railroad car of sorts being able to use it anywhere in a chain. As an example, my son uses the 2 wheel BCS tractor, with a sulky trailing it, and the trailer mentioned above behind the sulky, and the wood splitter behind the trailer.
