Sch 40 pipe or black iron pipe
« on: Apr 20, 2013, 08:32:19 PM »
( I dont want to build a cage wtih this.NO CAGE) After reading many posts about this,when you say schedule 40 pipe are you talking about the black iron pipe you can buy from Home Depot or Lowes,or  are y'all  talking about pipe from a plumbing supply store. The reason I ask  is because I was at Home Depot and looked at the pipe they had and the pipe they had didnt say sch40 on it. Now 2 pieces did say sch40 on it ,but they looked different (no black paint) and were made at a different compay. I may build a bumper with this pipe. I understand that DOM and HREW are better and if I were caging the truck I would use this tubing. I'm down to the very end of the build very short on cash and ready to be finished (so is the wife).

Schedule 40 only refers to the wall thickness.

Alright maybe I should rephrase the question. Is the pipe that I hear mentioned and seems to get bashed alot,the same type of pipe they sale at lowes or the depot? I want to make sure,I wouldnt think that it was.

Pipe at lowes or home depot is for moving a fluid not structural needs

some people will say that 1. 1/4 sch 40 is better (And cheaper) than HREW for slider/bumpers/ non structural parts

then there are the  "pipe is for poop" people, then the "use nothing but chrome molly" people...  the fact of the matter is.  some pipe is strong enough to be used for a cage, its heavier by linear foot than HREW, dom hrew, and obviously CroMo. When compared to strength vs size.

dont know if that made since.  sorta did to me


anyway, i was always in the pipe for non life saving use only crowd.  Until i witnessed a fully pipe built roll cage in a toyota do an ass over flip and come out un-scathed....  not saying i would use it, but if built right pipe does seem to serve its purpose.

Those are some huge welds!

Slider or bumpers maybe but a roll cage, no.

If I wheeled hard enough to need a roll cage the exta money would be worth it.

For sliders I'd get Marlins( :greengrin:) if shipping wouldn't rape me. :tantrum:

Strength is all relative. With a steel or iron pipe, you need a thicker wall, the higher strength steels, you can go thinner on the wall, have the same strength you need and have a lighter cage or bumper, thats the idea behind using chromolly or dom

  I would love to have a MC front bumper but its going to be somewhere between 120.00 to 160.00 for shipping. Thats why I figured I would build my own. Shiping is a killer. I've read several of the post on pirate about poop pipe,black iron pipe and water sprinkler pipe. Somewhere in one of the many threads I read I got the feeling that the pipe folks are talking about is not the pipe at Lowes or Home Depot. Baiscally I believe what I read was "dont by the :pokinit: at Home Depot" but then in another thread a person says that their sliders or bumper is made out of 1.25 sch40 from Lowes. Its a bit cofusing. Is the 1.25 or 1.50  sch40 at a metal supply different than the 1.25 or 1.50 sch40 sold at Lowes or Home Depot?

No, they're all the same. You can generally get sch40 pipe from a pluming supply house cheaper

Do not post misinformation. Pipe is not all created equal, The pipe used in plumping is far different than the pipe used in structural building ( yes i said structural, you think buildings are made from hrew/dom?).Towers are not built from hrew/rew/dom but from PIPE.  There is even seamless pipe that is made the same way as "dom".

I'm talking strictly sch 40 between blowes and hd, and a pluming supply house. It doesn't matter where you get it (unless one is imported and one is domestic)

Just remember the silver color pipe is galvanized it is for water, Bad fumes come off it if you weld it. The black iron pipe is for gas lines and is painted that is what you can use.And yes it is sold at Lowes and HD. We have built a lot of tree bars and bumpers out of it, No it is not as good as DOM but it is better than wood.

Bad fumes is a understatement, its toxic. Zinc fumes and it can make you very sick, plus gives you crappy welds. If you ever breath it in, go drink a bunch of mlik, it will help pull it out of your body

The stuff you want is uncoated sch. 40 pipe.  It is the same as hrew but made to pipe dimensions for diameter and wall thickness.  I believe the grade is A53f or something close.   I work at a steel fab shop and we use tons of this, not for cages, but catwalks and handrails and columns for steel buildings.  It bends the same as tubing but needs pipe size dies.  We have a real nice hydraulic bender at work and if I decide to do a cage I'll probably use this pipe.  Hope that helps someone.

I would be careful about using it for a cage.  We used it for bumpers and tree bars and we found that it breaks a lot easier than DOM, Not as critical for a treebar but I would never use it for a cage.
