Industry News & Market Facts
Pipe threading machines remain essential equipment in plumbing, construction and industrial installation. With sustained global investment in water supply, gas distribution and building infrastructure, the demand for efficient pipe threading equipment has grown steadily across international markets.
- Electric pipe threading machines significantly reduce threading time compared with manual threading tools, improving on-site productivity.
- Standardized BSPT and NPT thread forms ensure threaded connections are interchangeable across different countries and international projects.
- The growing focus on construction safety and work efficiency continues to drive adoption of motor-driven threading machines in plumbing, HVAC and fire protection sectors.
How to Use a Pipe Threading Machine
| Step | Instruction |
|---|---|
| 1. Prepare the pipe | Cut the pipe to the required length, remove burrs from both ends and wipe away any debris or oil. |
| 2. Select the correct dies | Choose BSPT or NPT dies that match the pipe diameter and the required thread standard. |
| 3. Install the die head | Mount the quick-open die head (1/2-3/4 inch, 1-2 inch) or self-open die head (2 1/2-4 inch) and lock it securely. |
| 4. Clamp the pipe | Place the pipe on the support, center it with the threading head and tighten the clamp firmly. |
| 5. Apply cutting oil | Apply cutting oil to the dies and the pipe end to reduce friction and heat during threading. |
| 6. Set the speed | Select the appropriate speed (12, 22 or 38 RPM) according to the pipe size and material. |
| 7. Start threading | Switch on the motor, engage the die head and apply steady pressure until the desired thread length is reached. |
| 8. Finish and inspect | Disengage the die head, switch off the machine, remove the threaded pipe and check the thread quality. |
Applications
Widely used in equipment installation and construction industries for plumbing, HVAC, fire protection, gas and water pipeline projects where threaded connections are required.
