[TowerTalk] 2" O.D. Pipe???

[AI4WM Bill]

Fence tubing is not seamless. It has a welded seam.  DOM has nothing to do with being seamless only.  If the tubing is extruded such as high quality aluminum it is seamless.

There are exceptions to all.  I have even seen masts made from EMT, irrigation pipe, and many different materials.  I prefer to stay with commercially available or mil. surplus masts for all but portable ops.

I use Chain Link Fence posts from Home Depot.  It's 2" outside diameter and
looks to be DOM.

You need tubing not pipe.  Pipe is measured by ID, tubing by OD.  You want
DOM (drawn over mandrel) tubing, which is only available at steel suppliers,
not Home Despot.

Hello All,

I went in search of 2 Inch O.D. pipe
on the internet!!

Guess what?  I can't find any!!!!

The outside diameter of pipe is
either 1.9" O.D. for 1.5 inch pipe or
2.375" O.D. for 2 inch pipe!!!
Nothing in between....

What am I missing??


Thanks for any help for the uninformed...
