Product Description
The SUNTECHMACH STB80E electric hydraulic pipe bender is designed for precision cold bending of thick-walled pipes (gas, water and steam pipes, black iron pipes, galvanized pipes, Schedule 40 & 80) up to 90°, following GB/T 3091, DIN 2440, EN 10255 and BS 1387 standards. Powered by a 750W electric hydraulic pump (110V/220V), it delivers 20T of bending force on 1/2"-3" pipe without manual pumping. Built on a one-piece welded steel frame with wheels and foldable stand.
| THE PROBLEM | HOW WE SOLVED IT |
|---|---|
| Manual pumping on 3" pipe is exhausting | 750W electric hydraulic pump — one-touch power, no hand pumping |
| Bending force not enough for SCH40/80 | 20T max pressure for 1/2"-3" thick-wall steel pipe |
| Motor burns out on long jobs | 750W copper-wound motor with thermal overload protection |
| Dies not complete in the box | 8 sets of bending shoes included: 1/2" to 3" |

Operation Guide
- Connect the electric pump to a grounded power supply (voltage per nameplate).
- Tighten the release valve (clockwise); loosen the vented oil bolt.
- Grease the die cover, swagging blocks and the pipe to be bent.
- Lift the upper plate and fix the correct bending die to the cylinder ram end.
- Turn the swagging blocks so the grooves face the pipe die; set them for the pipe length.
- Start the pump and apply hydraulic pressure to bend the pipe to the desired angle (max 90°).
- Release pressure by opening the release valve; the ram retracts automatically; lift the upper plate and remove the bent pipe.
Common Faults & Solutions
| Common faults | Reasons | Solutions |
|---|---|---|
| Ram won't fully extend | Air in hydraulic system | Purge air: loosen vented oil bolt, tilt cylinder 45°, pump until air removed |
| Slow response / weak force | Low hydraulic oil level | Top up quality hydraulic oil to about 1.2L |
| Oil leaks from cylinder seals | Too much oil | Keep oil level at about 1.2L, not above |
| Pipe slips during bending | Swagging blocks set incorrectly | Adjust blocks; make sure pipe extends beyond blocks |
| Bend angle inaccurate | Wrong die or block setting | Check die seating and block positions |
