🔍Mid-Range Pipe Threading Demands a Balanced Machine — Here Is What the ZT-80F-B Delivers
Contractor Concern
ZT-80F-B Solution
Small 2" threaders cannot touch 2 1/2" and 3" pipe — but 4" machines are too heavy and expensive
1/2" to 3" capacity — the practical sweet spot. Covers everything from small residential to fire protection and commercial mechanical room piping. At 105kg, it provides industrial-grade stability without the extreme bulk of a 4" machine.
Fixed single-speed machines either run too fast for heavy pipe or too slow for production work
2-speed gearbox: 32 RPM for fast production on 1/2"-2" pipe, 20 RPM for controlled high-torque threading on 2 1/2"-3" heavy-wall pipe. Match speed to pipe size and material — cleaner threads, longer die life.
Running out of the correct chaser size mid-job
3 complete BSPT chaser sets included: 1/2"-3/4", 1"-2", and 2 1/2"-3". Every size covered from the smallest residential pipe to full 3" industrial pipe — no separate purchases needed.
Machine cannot handle the torque required for 3" schedule 40 or 80 steel pipe
1300W copper induction motor with large modulus oblique gear main shaft. Engineered to deliver the high torque required for 3" steel pipe threading without bogging down or stripping threads.
Pipe clamping fails under heavy threading torque — scrapped pipe wastes time and money
Jagged hammer panel chuck design. Unique non-slip gripping surface prevents pipe rotation during high-torque 3" threading. Firm hold on steel, galvanized, and black iron pipe without surface damage.
Cutter wanders on large pipe — threads end up crooked
Double guide post cutting knife system. Twin precision guide posts eliminate blade deflection. Clean, perpendicular cuts every time even through 3" heavy-wall steel pipe.
Worried about after-sales when buying from overseas supplier
Manufacturer since 1989. Every machine tested on actual pipe before shipping. 12-month full warranty with free replacement parts. CE & ISO 9001 certified production facility in Hangzhou, China.
⚡Engineered for the 1/2"-3" Range — Balanced Power, Proven Reliability
⚙ 1300W Copper Induction Motor
Pure copper winding motor with superior heat dissipation. Low noise operation. Full-dimension threads in a single pass — no re-cutting. Designed for continuous daily production, not occasional use.
🔃 2-Speed Gear Transmission
32 RPM high speed for production runs on 1/2"-2" pipe. 20 RPM low speed for maximum torque on 2 1/2"-3" heavy pipe. Two-lever gear system with lightning-fast speed changes.
📏 3 Complete BSPT Chaser Sets
1/2"-3/4", 1"-2", and 2 1/2"-3" chaser sets included. Each set precision-machined for BSPT taper threads. Replaceable individually — buy only the size you wear out.
⚖ Large Modulus Oblique Gear
Oversized main shaft gear designed for the high torque demands of 3" pipe threading. Transfers power smoothly without slip or premature wear. Nitriding heat-treated for extended service life.
🔒 Jagged Hammer Panel Chuck
Aggressive gripping surface holds pipe firmly under maximum threading torque. Quick-release mechanism for fast pipe changes. Thickened cast iron construction absorbs vibration.
📏 Double Guide Post Cutter
Twin precision rails eliminate blade wobble and deflection. Accurate perpendicular cuts on steel, galvanized, and black iron pipe. Hardened cutting blade rated for thousands of cuts.
🏆 Manufacturer Since 1989
Professional pipe machine factory in Hangzhou, China. Exporting to North/South America, South Asia, and Middle East. Every machine individually tested before shipping. 12-month full warranty.
👷 Integrated Cutting & Chamfering
Built-in cutter and chamfering device. Load pipe once — cut, chamfer, and thread in three operations without moving the workpiece from the chuck. Saves valuable setup time.
🔃2-Speed Gearbox — Fast or Strong, Your Choice
32 RPM ⚡ High Speed
For 1/2" – 2" pipe production runs
Clean threads on smaller pipe at high speed. Ideal for residential plumbing, HVAC lines, and standard commercial pipe up to 2". Maximizes daily output when working small-to-medium sizes.
20 RPM 👷 Low Speed
For 2 1/2" – 3" heavy-wall pipe
Extra torque for schedule 40 and 80 steel. Controlled speed preserves die sharpness on large diameters. Essential for fire protection mains, process piping, and industrial installations.
📏3 Chaser Sets Included — Every Size Ready
📏 1/2" – 3/4" BSPT Residential & small commercial
📏 1" – 2" BSPT Standard commercial & HVAC
📏 2 1/2" – 3" BSPT Fire protection & process piping
