🔍Large Pipe Threading Is a Different Game — Here Is How the ZT-100F-A Wins

Industrial Contractor ConcernZT-100F-A Heavy Duty Solution
Threading 3" and 4" pipe manually is physically impossible1500W high-torque motor with large-modulus oblique gear main shaft. Generates the massive torque needed for 4" steel pipe threading — something smaller machines simply cannot do.
Different pipe sizes need different speeds — one fixed RPM ruins threads3-speed transmission: 38 RPM for small pipe (1/2"-1"), 22 RPM for medium (1 1/4"-2"), 12 RPM for heavy wall large pipe (2 1/2"-4"). Correct speed for every size = cleaner threads, longer die life.
Die heads for 1/2" pipe and 4" pipe are completely different systemsDual die head system: 100F Multi-Functional Die Head for 1/2"-2" + Swift Open Type Copying Die Head for 2 1/2"-4". Each optimized for its range. No compromise on small or large pipe.
Heavy machines vibrate and walk across the floor155kg (341 lbs) rigid cast construction. Massive weight and wide footprint absorb cutting forces. Rock-solid stability means the machine stays put and threads stay straight.
Buying a 4" threader is a major investment — need proven durabilityCE & ISO 9001 certified industrial-grade build. Nitriding heat-treated gearbox with enhanced wear resistance. All-aluminum alloy body designed for years of daily production duty.
Need to cut, chamfer, and thread 4" pipe — cannot lug it between stationsIntegrated cutting, chamfering, and threading in one station. Double guide post cutting knife + chamfering device built in. Load the pipe once, do all three operations without moving it.
Fire protection and industrial jobs demand flawless threads — rework costs a fortunePrecision-adjustable threading controls with wire length control panel. Consistent BSPT taper threads every pass. No rejects, no callbacks to the job site.

Built for the Heavy End — 1/2" to 4" Without Compromise

⚙ 1500W Industrial Motor
The most powerful motor in the product line. Copper winding induction motor delivers consistent torque across the full 1/2"-4" range without bogging down on heavy-wall 4" schedule 40 pipe.
🔃 3-Speed Gear Transmission
38 RPM (high speed) for production runs on small pipe. 22 RPM (medium) for standard commercial threading. 12 RPM (low speed) for maximum torque on 3"-4" heavy pipe. One lever changes speeds.
📏 Dual Die Head System
100F Multi-Functional Die Head handles 1/2"-2" with precision. Swift Open Type Copying Die Head tackles 2 1/2"-4" with automatic retraction. Each die head is built for its specific size range — not a universal compromise.
⚖ Large Modulus Oblique Gear
Over-engineered main shaft gear transfers massive torque without slip or wear. Designed for the extreme loads of large-diameter pipe threading in continuous industrial production.
👷 Integrated Operations
Built-in cutter frame with double guide posts for accurate perpendicular cuts. Built-in chamfering device. Load pipe once — cut, chamfer, and thread without repositioning. Saves time on every joint.
🏆 CE + ISO 9001 Certified
International safety and quality certification. Emergency stop accessible. Electrical system built to international safety standards for worry-free operation worldwide.
🔒 Heavy Cast Construction
All-aluminum alloy body construction. 155kg gross weight provides exceptional vibration dampening. Wide 900×640mm base combined with mass keeps the machine planted during heavy cuts.
🌐 Custom Voltage & Frequency
1500W motor available in 220V/380V/440V, 50Hz/60Hz configurations. Custom LOGO on machine plate and packaging available for OEM orders. 1-year warranty with free spare parts.

🔃3-Speed Advantage — The Right RPM for Every Pipe Size

38 RPM
📏 1/2" – 1"
High speed for small pipe production runs. Fast threading without quality loss on thin-wall material.
22 RPM
📏 1 1/4" – 2"
Balanced speed and torque for medium commercial pipe. Optimal for schedule 40 steel and galvanized pipe.
12 RPM
📏 2 1/2" – 4"
Maximum torque for heavy-wall large pipe. Controlled low speed preserves die life on schedule 80 and thick-wall steel.
