Threading steel pipe is how the old galvanized systems were joined, and it is still done for repairs and gas lines. A powered threader cuts clean threads that seal with dope or tape.
The die
A pipe threader cuts tapered threads into the pipe end, and the taper is what makes the joint seal as it tightens.
The oil
Cutting oil keeps the die cool and the threads clean, and it must be applied throughout the cut.
The fit
The threads should engage the fitting by hand a few turns, then tighten with a wrench — too loose means a bad cut.
The modern
Most home plumbing has moved to copper and PEX, but galvanized still appears in repairs and gas. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Santa Clara, a pro threads only where it is needed.
The dope
Threaded steel joints seal with pipe dope or tape on the threads. The taper does the work, but the sealant fills the tiny gaps.
