One thing they told me in Chassis fab that has stuck with me "Pipe is for poop"

:smack:

lol.... im sure it has been discussed here before..

But... there are different types of pipe.  I have seen some very well constructed cages/bumper/sliders/ even buggies made from THE CORRECT pipe that held up well... the biggest thing about pipe is. when it gets damaged, it will most likily damage the whole cage.. So first rollover may be fine, second not so good.. so on so on...

I have no problem using pipe for non life saving equipment. but it seems silly to me to use it as a cage.... it may give you the false sense of security that you are protected.
Those are some huge welds!

This has been coverd numerous times, some people have built pipe cages and been happy with them, but you have to remember, some people are really stupid... I would never use pipe, nor let anyone I care about use pipe.

6.5 Guidance on Welding
All welding must be of the highest possible quality with full
penetration and preferably using a gas-shielded arc.
The welds must be continuous around the whole perimeter of the
tube at each joint.
The external appearance of a good weld does not necessarily
guarantee its quality. However, evidence of poor quality welds by
appearance is usually a basis for rejection.
When using head-treated steel the special instructions of the
manufacturers must be followed (special electrodes, gas protected
welding). It must be emphasized that the use of heat-treated or high
carbon steels may cause problems and that bad fabrication may
result in a decrease in strength (caused by brittle heat-affected
zones), inadequate ductility and internal stress. Use of heat-treated
or high carbon steels is not allowed after 3/1/2005.
6.6 Material Specifications
Material: All cages built after 3/1/2005 shall be constructed of either
CDS (Cold Drawn Seamless) or DOM (Drawn Over Mandrel)
unalloyed carbon steel tubing containing a maximum of 0.3% of
carbon and with a maximum content of additives of 1% for
manganese and 0.5% for other elements. It is required that mild
steel be used after 3/1/2005.
The tubing must be bent by a cold working process and the
centerline bend radius must be at least 3 times the tube diameter. If
tubing is ovalised during bending, the ratio of minor to major
diameter must be 0.9 or greater.
The minimum size of tubing to be used shall be as follows:
Tubing size configuration 1: Allowed for all cars
Dimension
(in)
Dimensi
on (mm)
Use
22
1.75" x
0.095"
or
2.0 x 0.083"
45 x 2.5
or
50 x 2.0
Main rollbar (figure 253-39)
Lateral rollbars and their connections (figure
253-40)
1.5 x 0.095
or
1.6" x 0.083"
38 x 2.5
or
40 x 2.0
Front rollbar and lateral half roll bars, and all
other connecting and reinforcement members
23
Tubing size configuration 2: Allowed for cars weighing 2650 lbs or
less, in full rally configuration (with full fuel but without drivers).
Dimension
(in)
Dimensi
on (mm)
Use
1.5 x 0.120 38 x 3.0 Must be used for all portions of the main cage
structure including: Main rollbar, front rollbar,
lateral rollbars, and lateral half roll bars, and
all connecting members at the roof level.
1.5 x 0.095 38 x 2.5 All other connecting and reinforcement

Someone should make the poo-pipe and harbor freight poo-pipe bender info a sticky, seems like every 3rd thread is about one, the other, or both.
