Product Description
Detailed Description
Product Overview The Z₁T-N100 Pipe Threading Machine is a heavy-duty electric pipe threader designed for professional plumbing, fire protection, and industrial piping applications. Capable of threading pipes from 1/2" to 4" (DN15–DN100), it delivers precise, standard-compliant threads on carbon steel and galvanized pipes, ensuring fast, clean cuts for gas, water, and fire sprinkler systems. Built for durability and ease of use, this machine is ideal for both workshop and on-site construction environments.
Key Features Full-Range Threading: Handles DN15 to DN100 pipes (1/2"–4") in one machine, covering most common plumbing and fire protection needs. Dual-Speed Design: 24/8 RPM dual-speed output balances efficiency and precision, suitable for both small and large pipe sizes. Dual-Voltage Compatibility: 220V/380V options available, adaptable to different construction site and workshop power supplies. Sturdy Construction: Heavy-duty cast iron body ensures stability during high-load operations, built for continuous professional use. Standard-Compliant Threads: Produces clean, burr-free threads meeting BSPT/NPT/ISO standards, ensuring leak-proof connections. Applications Fire Protection Systems: Threading steel pipes for sprinkler lines, standpipes, and hydrant connections. Plumbing & Water Supply: Creating threaded connections for domestic water, gas, and heating pipelines. Industrial Piping: Threading process lines, compressed air systems, and mechanical equipment piping. Maintenance & Repair: On-site threading for pipe replacements, extensions, and retrofits in existing installations. Step-by-Step Operation Guide Preparation: Secure the machine to a stable surface. Install the correct die head for your pipe size and thread standard. Pipe Setup: Cut the pipe to the required length, deburr the ends, and clamp it firmly in the machine’s vise. Threading: Start the machine, apply cutting oil, and feed the pipe into the rotating die head. Adjust the feed rate based on pipe size for optimal results. Finishing: Reverse the rotation to retract the die head once the thread reaches the desired length. Remove the pipe, clean off excess oil, and inspect the thread quality.
Compatibility
Drop-in replacement
This Junyue grooved piping component is engineered for seamless compatibility with Victaulic Style 07 and Grinnell system layouts. Verify pipe OD, groove profile, gasket compound, pressure class, and project approvals before specifying as a replacement.
Technical FAQ
Application limits
- Can it be used for steam above 150 C?
- No. Do not use for steam above 150 C unless a written project-specific approval, rated gasket, and compatible body material are confirmed.
- Can it replace any grooved fitting without checking pipe OD?
- No. Pipe OD, groove standard, working pressure, gasket material, and certification scope must be matched.
- Is it suitable for potable water by default?
- No. Potable water use requires confirmation of coating, gasket compound, local sanitary approval, and project compliance.
- Can it be used in corrosive chemical service?
- Not by default. Chemical compatibility must be verified against the medium, concentration, temperature, and coating system.
