STT80 900W Electric Pipe Threader 1/2inch to 3inch for water pipe,gas pipe
Introduction
This machine is applicable to cutting, threading and inner hole chamfering (the chamferer is optional) of pipes for water, electricity and gas, and has the copying device able to automatically cut the standard taper pipe thread, with a reliable clamping device and an advanced cooling & lubrication system. Therefore, adopting this machine can lengthen the service life of the threading die, and avoid the deformation & slipping of the pipe clamp, so as to obtain the high-quality taper pipe thread. This machine is widely used in equipment installation, building and other industries, regarded as the ideal equipment to improve work efficiency, accelerate project progress, guarantee project quality and reduce labor intensity. (It is an ordinary round-steel threading machine, only applicable to the ordinary round-steel threading. The operating mode and machine structure are basically the same.)
Features
1. 900W copper sensing motor, small noise, long use life, fulfillment of full-dimension thread at one time.
2. Exclusive hard tooth-surface high-speed gearbox, with small noise, long use life and high efficiency.
3. Jagged hammer panel design, firm clamp pipe, convenient operation.
4. Standard collocation of 50A multi-functional die head, die is replaced to process the round steel and wire pipe thread.
5. Double guide post cutting knife is accurate and durable.
6. Enhance type guide post trunnion can upgrade the stable properties of machine.
7. Large modulus oblique gear main shaft gear, super-large torque for easy transmission.
8. Selection of high efficiency, quality and performance-price ratio.

Operation guide:
A. Threading:
(1) Pull the cutting knife frame and chamferer; put down die head to touch the copying block. After reliable positioning of die head, press the button to start the machine.
(2) Rotate the pipe in anti-clockwise direction, rotate the hand wheel of cutting feed, and make die head get close to the pipe.
(3) Apply force to the hand wheel of cutting feed, until die head makes 3 ~4 threads on the pipe.
(4) Then, loosen the hand wheel of cutting feed, so the machine starts automatic threading. When roller of die head goes over copying block and falls down, threading die will open automatically and the threading is completed (Z13 T–M18 threading machine is required to turn back to make the threading die exit). Z1T–50A threading die shall be loosened manually.
(5) Machine halt. Return to the carriage, until the whole die head exits pipe end. Pull out die head, lock the handle and pull up the die head.
Common Faults and Solutions
| Common faults | Reasons | Solutions |
|---|---|---|
| 1. Motor doesn’t work or work with intermittent sound | 1. Fuse is burnt down 2. The plug is not well connected 3. The internal part of the cable is broken 4. The button switch is not well connected 5. 100UF Capacitor breakdown 6. Environment temperature is too low, and lubricating grease solidifies. | 1. Detect the broken part with a multimeter and use a new fuse 2. Replace the plug or socket 3. Replace the power cord 4. Replace the switch 5. Use a new capacitor 6. Operate indoor or help it to start up |
| 2. Pipe fails to be fixed and slips during threading | 1. Insufficient hammering force 2. Clamping jaw tip turns over 3. One clamping jaw tip breaks or has a gap | 1. Hammer hard 2. Adjust clamping jaw tip 3. Use a new clamping jaw tip |
| 3. Cutting knife fails to cut, and fails to produce proper threads | 1. Sharp corner of cutting knife is worn out and becomes an arc 2. Pin roll of cutting knife is worn out 3. Cutting force is insufficient | 1. Replace cutting knife blade 2. Replace pin roll 3. Cut more vigorously |
| 4. Knife cannot cut during threading | 1. Opening of threading die is too small at the start of threading 2. Several teeth of knife head are broken 3. Knife head doesn’t match 4. There is scrap iron in die groove | 1. Use threading die correctly 2. Replace knife 3. Re-install knife head 4. Clean threading die head |
| 5. Front chuck loosens and falls down | Screws loosen due to long-term use | Inspect them timely |
| 6. Main shaft is heated and jammed | Insufficient oil | 1. Add oil timely 2. Exit beam barrel and repair shaft sleeve |
| 7. Cooling oil doesn’t come up | 1. Oil line is jammed 2. Oil hole doesn’t align after dismantling and re-assembling fulcrum shaft of die head. 3. Oil leaks from oil pump after stopping use for a long time 4. Oil pump is worn out 5. Rotor pin roll of oil pump is broken | 1. Clean oil line 2. Re-assemble 3. Add some cooling oil into oil pump 4. Replace oil pump |
| 8. Oil leakage | 1. Oil line plugging leads to falloff or rupture of oil line. 2. Oil draining screw in the oil tank isn’t tightened | 1. Inspect plugging point and replace oil line 2. Tighten oil draining screw |
| 9. Cooling oil leaks into motor | Skeleton type oil seal of oil pump PD8×22×8 is damaged | Replace a new oil seal or oil pump |
| 10. Three-phase motor is burnt down | Phase loss or bad contact | Carry out the winding and check the circuit |
| 11. Single-phase motor is burnt down | 1. Starting voltage is too low 2. Environment temperature is too low, and lubricating grease solidifies. | 1. Wind wires and inspect voltage; replace qualified power line and power supply 2. Wind wires and carry out indoor operation |
| 12. Unilateral threads | 1. Oval pipe 2. Clamping jaw tip breaks or has a gap | 1. Replace the pipe 2. Replace the clamping jaw tip |
