PEX-AL-PEX Pipe and fitting preparation before pressing
|
 |
(1) Cutting the pipe with a right pipe cutter, make
sure cutting the
PEX-AL-PEX pipe vertically to have a good round
shape (Picture 2.1, Ardi QGQ-75 cutter). |
|
|
|
 |
(2) Choosing the right size of mould and reamer head
for the corresponding
PEX-AL-PEX pipe size, placing the pipe on the
mould as the picture shows below(Picture 2.2). |
|
|
|
  |
(3) Finishing the mould installation and stabilizing
the
PEX-AL-PEX pipe between the moulds．(Picture 2.3-2.4). |
|
|
|
   |
(4) Rotating the handle to let the reamer head reach
the
PEX-AL-PEX pipe end, and then keep rotating till the reamer
head bevels the inner pipe into a certain depth. The
beveled depth should be approximately close to the
length of the fitting insert.(Picture 2.5-2.7). |
|
|
|
 |
(5) Using T-reamer (Ardi JD 40-75) to round the
PEX-AL-PEX
pipe. Inserting the reamer completely inside the
multilayer pipe
and rotating the reamer in one direction for several
times to form a round pipe end. (Picture 2.8). |
|
|
|
  |
(6) Placing the
PEX-AL-PEX pipe into the sleeve until the pipe
end reaches the sleeve bent end.(Picture 2.9-2.10). |
|
|
|
 |
(7) Inserting the
PEX-AL-PEX fitting into the sleeved pipe, till
the sleeved
PEX-AL-PEX pipe end reaches the fitting shoulder block.
(Picture 2.11). |

Preparation and pressing with Ardi YYZ integral hydraulic
tool |
|
 |
 |
Step 1: Choosing the right size of jaw for
the corresponding PEX-AL-PEX pipe, and then releasing the pin from
the clamping head. |
|
|
|
 |
Step 2: Installing the jaw in the clamping head and
shutting the pin back on position. (Picture 3.3). |
|
|
|
  |
Step 3:
Releasing the hydraulic pressure in the clamping head by
rotating the switch at anti-clockwise direction (Picture
3.4), and then rotating the switch back at clockwise
direction (Picture 3.5) till it is tightened. |
|
|
|
  |
Step 4: Opening
the jaw by pressing its tail with hand and placing the
installed fitting inside the pressing surface, then
closing the jaw by releasing the tail, make sure the
sleeve is totally assembled with the pressing surface.
(Picture 3.6-3.7). |
|
|
|
 |
Step 5: Pumping
the pressure to the clamping head by operating the
handle of the pump with up and down direction, repeating
this procedure until the jaw is completely closed.
(Picture 3.8) |
|
|
|
 |
Step 6:
Releasing the pressure on the clamping head by rotating
the switch again at anti-clockwise direction. (Picture
3.9) |
|
|
|
  |
Step 7:
Releasing the installed PEX-AL-PEX fitting from the jaw. (Picture
3.10-3.11). |
|

|
Preparation and pressing with Ardi YYF III separated
hydraulic tool |
|
|
 |
(1): Connecting
the oil tube with the manual hydraulic pump and the
clamp head, make sure the connection is absolutely
tight. (Picture 4.1). |
|
|
|
 |
(2): Choosing
the right size of jaw for the corresponding PEX-AL-PEX pipe, and
then releasing the pin from the clamping head. (Picture
4.2). |
|
|
|
 |
(3): Installing
the jaw in the clamping head and shutting the pin back
on position (Picture 4.3). |
|
|
|
 |
(4): Releasing
the lock from the handle of the pump. (Picture 4.4). |
|
|
|
  |
(5): Releasing
the hydraulic pressure in the clamping head by rotating
the switch at anti-clockwise direction (Picture 4.5),
and then rotating the switch back at clockwise direction
(Picture 4.6) until it is tightened. |
|
|
|
  |
(6): Opening
the jaw by pressing its tail with hand and placing the
installed PEX-AL-PEX fitting inside the pressing surface, then
closing the jaw by releasing the tail, make sure the
sleeve is totally assembled with the pressing surface.
(Picture 4.7-4.8) |
|
|
|
 |
(7): Pumping
the pressure to the clamping head by operating the
handle of the pump with up and down direction, repeating
this procedure until the jaw is completely closed.
(Picture 4.9). |
|
|
|
 |
(8): Releasing
the pressure on the clamping head by rotating the switch
again at anti-clockwise direction. (Picture 4.10). |
|
|
|
  |
(9): Releasing the installed
PEX-AL-PEX fitting from the jaw. (Picture 4.11-4.12). |
|

NOTE: IT IS SUGGESTED THAT THE INSTALLATION
PROCESS OF THE LARGE-SIZE PEX-AL-PEX PIPE IS BETTER TO BE COOPERATED WITH
TWO PEOPLE. |
