I Forge Iron

Recommended Posts

Iron Pipe sizes remain the same on the OD regardless of schedule. The higher schedules have thicker walls, always taken up on the ID. This way standard threaded fittings work on various schedules of pipe.

Tube sizes are measured by ID .

The size designation is the nominal size, neither the ID or OD of 1" pipe measures 1"

If you are buying pipe for forging , It's best to specify domestic grade as it seems to be less prone to splitting at the welded seam. This is not what is usually available at big box home centers.

The very best pipe for hot forging is schedule 160 DOM [drawn over mandrel ] which is seamless. Expensive stuff and not always easily available.

Good luck with that, domestic pipe is hard to find these days. The stuff usually found in stores like Lowes & Home Depot is probably A120. A53 & A106 are better grades and less likely to split. The grade is usually marked on the pipe.
