SHT800-SHY Hdpe Pipe Plastic Butt Fusion Welding Machine with
heating plate
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.The part outside the frame of the pipe shall be
supported by supports to reduce friction, and then be fastened with
slips.

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.
