Basic Frame

Featured by

- Oil seal kit‘s pressure performance stays in more stable way.

- 4sets quick coupling helps operator to prepare the machine better before and after welding, and we use good quality product which ensures no hydraulic oil leakages when unplug or plug in.

- Using integral shaft (top chromate treatment) instead of assembled shaft, ensure the chassis strength to avoid possible frame twist or deform when dragging the pipe with extreme parameters.

Heating Plate

Featured by

- We use Teflon coating of the heating plate, which is the best in industry. It's much sticker to aluminum plate, more non-sticky to plastic pipes surface. Temperature deviation of different points on heating plate is 2-3 degrees (small size machine) and 5-6 degree (big size machine).


Featured by

- Safety Switch, which guarantees the operators' security, even with power on, the trimmer will not be running if operators do not press the button.

And a stable support

Hydraulic Power Station

Featured by

- Solid relays have a bigger load capacity and working in more stable situation, which has much longer life.

- The circuit breaker works with electricity leakage protection switch. Including the earth wires, there're 2 elements to activate the protection when electricity is leaking.

- Non-fan motor (small size machines), water proof, sand-proof and dust-proof at higher level. The motor provides sufficient/full power to provide support for hydraulic power. i.e. V355 could reach to maximum 80bar.

General Welding Knowledge

Part name: Pressure Gauge
Functionality: Show the force applied during welding
Verify the functionality before welding
Part name: Timer
Functionality: Set the time applied to each welding process
Verify the functionality before welding
Part Name: Temperature Controller
Functionality: Set and control the temperature applied to the welding
Verify the functionality before welding
Heating plate
Check the integrity of Teflon coating.
Should verify the heating plate if could reach to the temperature which set by temperature controller.
Before welding, be sure the trimmer works well.
Be sure the blades are sharp enough and could face the pipe end properly.
Please make a test welding.

Welding procedure

1. Check whether the specification and pressure grade of the pipe to be welded are correct, and check whether there are bumps, bumps and scratches on the surface. If the depth of the scar exceeds 10% of the wall thickness of the pipe, it should be partially removed before use;

2. Clean the oil or foreign matters at both ends of the pipe with a clean cloth;

3. Place the pipe to be welded in the frame slip, so that the length of both ends is equal (as short as possible without affecting the milling and heating). The part outside the frame of the pipe shall be supported by supports to reduce friction, and then be fastened with slips;

4. Put in the milling cutter, first turn on the power switch of the milling cutter, then close both ends of the pipe and apply appropriate pressure until there are continuous chips at both ends, remove the pressure, wait for a moment, then withdraw the movable frame, turn off the power supply of the milling cutter and take out the milling cutter. The chip thickness should be about

0.2-0.5mm. The chip thickness can be adjusted by adjusting the height of the milling insert;

5. Close the two pipe ends and check the alignment of both ends. The misalignment at both ends of the pipe should not exceed 10% of the wall thickness, which can be improved by adjusting the straightness and the elastic slip of the pipe; the gap between the two ends of the pipe should not exceed 10% of the wall thickness, otherwise it should be milled again until the above requirements are met;

6. Clean the dust and residue on the surface of the heating plate (pay special attention not to scratch the nonstick layer on the surface of the heating plate);

7. After the temperature of the heating plate reaches the set value, put it into the rack and apply the specified pressure until the minimum crimping on both sides reaches the specified value;

8. Reduce the pressure to the contact pressure and continue heating for the specified time;

9. When the time is up, withdraw the movable frame, quickly take out the heating plate, and then close the two pipe ends, with the time interval as short as possible;

10. Raise the pressure to the specified welding pressure, lock the fixing bolts on both sides of the frame, and keep the pressure for natural cooling. After cooling for the specified time, the fixing bolt is fully opened. Loosen the slip and take out the connected pipe.

Different method for different pipe

Welding joint overview and analysis:

Qualified joint by visual checking.

Narrow and fall bead. Too high pressure while welding
Too small bead. Pressure is not enough while welding.
A ditch in the ioint. Temperature is not reached or change-over time istoo long before welding.
Misalignment. Welding under the condition that the misalignmentexceeds 10% of pipe wall thickness while align the two ends
