STT100-HV 2300W High-Volume Production Pipe Threader 1/2-4 Inch with 36RPM Continuous Duty Motor & Auto-Lube System

The SUNTECHMACH STT100-HV is a production-grade pipe threading machine engineered for contractors and fabrication shops that measure output in tons, not pieces. With a 2300W continuous-duty copper motor, 36 RPM high-speed spindle, and 100% duty cycle rating, it eliminates the biggest bottleneck in any pipe workshop — machine downtime. This is threading built for the long shift.

• Continuous-Duty Motor: 2300W (3.1 HP) 100% copper winding with forced-air cooling and external aluminum heat sink fins. S1 duty cycle rating for non-stop 8-hour operation.
• Dual-Speed Gearbox: 36 RPM high-speed mode for diameters up to 2 inches; 18 RPM low-speed torque mode for heavy-wall pipe up to 4 inches.
• Auto-Retract Die Head: Opens automatically at the preset thread depth. Eliminates manual reverse cycling, cutting total cycle time by approximately 30%.
• Quick-Release Cassette System: Cam-lock mounting with pre-loaded, color-coded cassettes for each die size. Complete size changeover in under 3 minutes.
• Auto-Lube System: 5-liter reservoir with adjustable constant-flow pump and low-level warning indicator. Refill port accessible without stopping the machine.
• Dual-Voltage Ready: Auto-sensing inverter accepts 220V single-phase or 380V three-phase input via a simple terminal block swap. Soft-start eliminates inrush surge.

• 1x STT100-HV threading machine with auto-retract die head and forced-air cooling system
• 3x Pre-loaded quick-change die cassettes (NPT: 1/2 inch - 3/4 inch, 1 inch - 2 inch, 2-1/2 inch - 4 inch)
• 1x 5-liter automatic oil circulation system with adjustable flow pump
• 1x Heavy-duty industrial stand with leveling feet and vibration-damping pads
• 1x Digital NPT thread gauge (go / no-go) for on-site QC verification
• 1x Spare carbon brush set and comprehensive maintenance tool kit
• 1x Operator training manual (English) and 12-month warranty registration card

Engineered for high-output pipe fabrication workshops and contractor operations running combined shop production with field installation. Handles Schedule 40, Schedule 80, and Schedule 160 steel pipe conforming to ASTM A53 Grade B, API 5L Grade B, and EN 10255 standards. Ideal for pre-fabricated pipe spool manufacturing, fire protection sprinkler system preparation, HVAC mechanical room piping, oil and gas facility maintenance workshops, water treatment plant pipework, and marine shipbuilding pipe fabrication.

Every STT100-HV is shipped in a reinforced export-grade plywood crate with internal steel frame bracing rated for 500 kg stack load. Vibration-isolated motor and gearbox mounts prevent transport damage. Each unit completes a factory acceptance test: 4-hour continuous run-in at full rated load, 50 consecutive thread samples measured against NPT/ANSI B1.20.1 and ISO 7-1 standards, 500 VDC insulation resistance testing, and noise level certification. CE and ISO 9001 certified. Covered by a 12-month comprehensive warranty with 48-hour priority parts dispatch to major global markets.
