Supporting of Pipe

[ullas2711]

Dear All,
I need to run a 1" Galvanized air pipe in a ware house of height 9 mtr. The pipe will be running at a height of 4 mtr from the ground. My question is regarding the supporting of this pipe. Can I use a threaded rod for a length of 5 mtr to support this pipe from the ceiling? If not please suggest any alternate suggestions.

Thanks in advance

Why not, eventho, it may look a little strange, however, I personally would look at anchoring the pipe on building or foundation walls and or columns.

Any air movement will swing it, or even internal flows may cause lateral vibrations. It should be anchored to the wall.

Ullas2711:
And, why can’t this 1" pipe line be hung off the underside of the roof structure, much nearer some solid structure, at about 9m? I would be concerned about vibration and about it swinging in the wind (any lateral loads) also. Alternatively, you might come up with some fairly light angle iron framework, a std. detail, a two legged “A-Frame shape” or even a three legged hanger which offered some stiffness along the length of the pipe also, much stiffer than a 5m long rod, for all of the hangers.

The only concern I have is that, from what I can gather, the pipe will be hung from a collection of 16-foot rods with undisclosed rigidity, diameter, and endpoint restraints. The minute you open a valve in the air piping, or if the air flow through (or out of) the pipe changes suddenly, then either nothing significant will happen or else some interesting displacements / oscillations / animations will happen. So, the "Y" restraint (assuming Y-axis vertical) is easy enough to understand, but without at the very least one "X" and one "Z" restraint somewhere in the system, you might see a lot of movement that you don't want.

I'm with others suggesting either different routing or otherwise better support/anchorage. Depending on layout, length of piping and any possible thermal variations in a compressed air line, as well as seismic or modal actions (I guess where applicable), a single rod hanger 5m long also sure wouldn't provide much lateral/sway support (and neither would just the "air" on either side of the suspended line!!)

And when you do figure out on the installation, I would pitch the pipes so as to drain the condensate back into the receiver.

Dear all
Thanks for the feedback. I don't have any other points to support the pipe. The only option is to use the purlin in the roof. I have come across Gripple support system which uses cables to support the pipe. U can find more info at

But not sure how effective it would be....
