Are you going to enter a toilet in KOH?

I doubt it would pass tech but I know its plenty safe maybe someone that knows the rules will chime in.

No fuckwad,another guy asked me the same question and I could not answer him mine is getting all built from 1.75 dom, I am wondering what the correct terminology for poo pipe is and if infact would pass tech.

If this guy is your friend, you should ask him, "Would you trust your life in a roll-over to poop-pipe?"

From what I have seen the technical inspection for KOH has not yet evolved to the point of taking sonic-wall measurements and hardness measurements, etc. That being said, I would not run poop-pipe in my cage. Tell your friend to cut out the offending tubing and replace it. It will be a small part of the overall budget; trust me.

Why trust your life to anything within your control? If you valued your life above all else like you are saying you wouldn't be driving a vehicle in a fashion in which a roll over was likely.

So all you are really saying is that you value your life at a couple more dollars/foot than someone else. Is that such a surprise? 99.9% of the population value their life greater than you in that they think risking it to drive over some rocks or through some sand is dumb / not worth it.

Personally, I think they're more sane than you or I.

Why is there even a question anyway? Shouldn't the official KOH rules be posted online somewhere for all potential competitors to access? And should not the rules makers have anticipated the poop pipe debate? People aren't honestly saying that this is totally out of left field, completely unexpected? They could easily just say, "poop pipe not allowed." So do they or do they not? We don't need another poop pipe debate thread. The OP was not asking "Is poop pipe strong?" The OP is just asking if poop pipe is legal in KOH. The answer should be, "Look at the rules dumbass," and if the rules aren't readily available the answer should be, "WTF aren't they?" and if they are and poop pipe isn't covered the answer should be, "WTF isn't it?" The dude shouldn't be crucified just for asking. The only dumb question is the one not asked.

exactly all I am asking poo pipe legal what is it? The rule states dom,whr,wcr,and crew tube? So where does pro pipe fall into there? This is not a debate thread! And there is no buggy to see pics of it was a question I was asked and could not answer!

See section 6.2.5.2 .

So I guess his question is whether or not poop pipe falls in those definitions since I see nothing directly saying "no poop pipe."

most rules just list "round steel tubing" or "structural steel tubing" with a minimum diameter and wall thickness per total vehicle weight...

According to what type of pipe you get, it can be just as strong or stronger than HREW.

Normally not as strong or nicely finished as DOM, but can/is still plenty strong.


I've used cheap threaded water pipe, high pressure gas pipe, handrail pipe, HREW, and DOM over the years on various rigs/projects.

I like working with DOM the best, just like I like cold rolled steel plate the best too.

Funds do not always allow the "best" to be used. And some projects don't require the "best".

My heeps cage is made from 1.9"OD seamless(no interior flash) with a .145 wall. My rig is around 4000lbs. My "poo pipe" says ERW on it and had a niver finish on it that the last ERW I bought.

So by the rules.......I'd be legal?

Pipe and tube are just ways differnet ways of dimensioning round cylindrical bars with holes through the middle.

You can buy Drawn Over Mandrel (DOM) pipe or tube.... You can get seamed tube/pipe that has been drawn over a mandrel, you can get seamless tube/pipe that has been drawn over a mandrel....... They are just manufacturing process.

After you have decided on the manufacturing process you like - you can then chose the material you want to use.

Not all combinations of materials/manufacturing process are available based on whats worth manufacturing.

Unless you quote a spec that defines the manufacturing process and the material being used you are comparing items that 'might' be the same, or 'might' not.

I think your talking bollocks when you dismiss pipe.......

If your reading those rules the same way I am, then I'd say yes. Which means I am too.

Yup. If I specify that I want the stuff from India, I get good quality clear coated pipe. If they send me korean shit, its the black painted gummy stuff. Night and day differance but my supplier apparently cant tell them apart.

I've done side by side comparisons on the two and people cant tell them apart.

It's the perfect material...cheap, AND you can get it galvanized so you don't have to paint it. You should do it.

And the fumes smell good when you weld over the galvanization!

Depends on your definition of "in spots".

A foot or two here or there where it's appropriate, sure. A sleeve somewhere or maybe for coolant (although it's too thick for either of these applications).

In my A- or B- pillars or halo or door bars or x-bars? I'd go with something with a certification I needed.

What Breg90 said.

I think the simple answer is that it is "Pipe". Looks like the rules require "Tube".

Pipe is certified for its corrosion and pressure characteristics.

Tube is certified for its flexural and stiffness properties.

It is entirely possible that a round cylinder with a hole through its length could be certified for both. Structural properties are published for what you refer to as "pipe", as well as "tube".

If pipe is only for carrying poop, then why did ASTM publish standard # A53?

So is this 14.375" ASTM A106C pipe or 14.375" ASTM A519 1026 tube?

I do agree that pipe and tube are not the best terminology to use here. It would be best if it was specified as a list of acceptable ASTM specifications.

I see the word "tube" a lot in that MTR.

What do I win?
