Thread Galvanized Pipe

Threaded galvanized pipe in a T fitting.

Galvanized pipe is steel pipe with a coating of zinc that retards corrosion of the steel. It is used for handrails, replacing existing galvanized pipe and as a conduit material. Galvanized pipe can be cut and threaded to fit into threaded pipe fittings made from galvanized steel, copper, plastic or other material. After cutting galvanized pipe, be sure to file burrs from the end with a metal file before threading the pipe.


1. Determine the proper size thread die to use by measuring the outside diameter of the pipe and the number of threads required per inch. Refer to the Resources section for a chart to determine the proper thread die required for a tight seal.

2. Place the galvanized pipe in a vice on a workbench that is high enough off the ground to accommodate the handle of the pipe threader.

3. Place the proper-sized die into the pipe threader.

4. Position the pipe threader on the end of the galvanized pipe. Move the handle down firmly, but straight, to start the thread.

5. Apply a generous amount of thread cutting oil to the end of the pipe.

6. Position the handle slightly higher than the waist and push down on the end of the handle. Ratchet the handle back up to the starting position and repeat. Continue threading the pipe until the end of the pipe meets the end of the die.

7. Reverse the ratchet mechanism to remove the pipe threader from the galvanized pipe. When reaching the end of the pipe, remove the pipe threader carefully so the thread at the end is not damaged.

Tips Warnings

Make sure the handle of the pipe threader is clean and dry to avoid slipping and damaging the threads.
