4. Step-by-Step Threading Procedures

Quality threading is preparation plus precision. Follow these fundamentals for consistent results.

4.1 Pipe Preparation and Die Setup

Pipe Selection and Material Compatibility

• Use steel, brass, and stainless steel pipes for threading; avoid copper due to thin walls.

Measuring and Cutting

• Mark length, cut square using a saw or roll cutter, and re-check straightness; recut if needed.

Reaming: Removing Burrs

• Use a cylindrical rotary reamer; wear gloves and goggles.

Die Selection and Assembly

• Match die to pipe size and thread pitch (e.g., standard 3/4-inch-per-foot NPT). Clean and align dies carefully to avoid crooked threads.

Die Head Setup

• Align with a copying block or guide—much like setting up a metal embroidery hoop. If you have aligned a magnetic embroidery hoop, the feel is similar. Secure all components firmly.

Material Compatibility Warnings

• Avoid threading copper pipes.
• Favor steel or brass for gas and water lines.

4.2 Threading Execution and Quality Control

Manual vs. Powered Threading

• Manual: Best for 1/2"–2"; budget-friendly, more physical effort.
• Powered: Ideal for larger diameters or volume work; higher precision with a learning curve.

Threading Sequence

1. Machine Setup: - Align die head with the pipe. - Apply cutting oil liberally to die teeth.
2. Initial Engagement: - Rotate anti-clockwise and advance die head. - Make 3–4 threads before loosening the feed handle.
3. Full Engagement: - Continue until all die teeth are cutting; maintain steady pressure.
4. Oil Application: - Keep dies and pipe well-oiled; machines like the RIDGID 1224 provide through-head oiling. For a non-metal analogy, many rely on magnetic hoops for embroidery machines to maintain even tension.
5. Finishing Up: - Back off the die head and wipe chips and excess oil.

Quality Control: Inspecting Your Threads

• Gauge pitch, depth, and alignment.
• Watch for crooked or incomplete threads from misalignment, uneven pressure, or poor lubrication.
• Clean chips and debris thoroughly.

Best Practices

Troubleshooting Common Issues
