Introduction

Stated that the basic machine it's suitable for all kinds of pipe, fittings and stub end available on the nowadays market. Here follows all the
different welding configurations of the machine:
1) Pipe with Pipe, standard configuration of the machine
2) Pipe with long spigot fitting, standard configuration of the machine
3) Pipe with short spigot fitting, to achieve this kind of welding it is strongly suggested to configure the machine with three moveable
clamps and 1 fixed clamp. Furthermore you must use the upper fittings clamp to fix better the fittings to the fixed clamp
4) Fitting with short spigot stub end, to achieve this kind of welding it is strongly suggested to configure the machine with three
moveable clamps and 1 fixed clamp. To fix the stub end you must use a special accessory called stub end device. Place the 4
brackets at the appropriate size punched on the stub end device. Fix the stub end by tighten the bolt of each bracket. The stub
end device is supplied with a fixing ring and you can install it on each clamp of the machine.
5) Pipe with short spigot stub end, to achieve this kind of welding you can use two different configuration of the machine (5 or 6)
6) Pipe with short spigot stub end, to achieve this kind of welding you can use two different configuration of the machine (5 or 6)

4.2 Machine's preparation
It's strongly suggested to use pipe rollers for the sliding of the pipes to be welded and if it's possible positioning the machine
with wooden table below, such cares will avoid additional efforts to the machine.
a)

Set up the working area so that welding is protected from the weather. Position the machine's components as per following figure
and eventually utilize wooden panels

b)

Connect the flexible hoses of the hydraulic unit to the machine

PT 250 Operating Manual

Connect the plugs to the power supply (Hydraulic unit, Facing tool and Heating mirror) after checking that the main power
supply is within a 10% of the specified one “ Warning Heating Mirror start to warm up ! “
Select the correct temperature on the heating mirror
In case fit the inserts of the diameter to be welded into the machine

4.3 Pipes positioning into the machine and facing operation
a)
b)
c)

d)
e)
f)

Open the movable trolley of the machine by means of acting the lever A (hyd. Unit) and take
it in position A2
Position the pipes into the machine taking care to leave enough space for the facing tool inserting
Check the pipes alignment, in case adjust it by means of tighten or loosing the clamps bolts.
The maximum misalignment could be lesser than 10% of the pipe or fittings wall thickness.
In any case the misalignment cannot be over than 2mm.
Clean the pipe ends
Fit in the facing tool between the two pipe's ends to be faced, by means of connecting the facing
tool into the special supports. Connect the safety pin and start the facing tool engine
On the facing tool there is a facer stopper (see the figure aside). In case of one of the pipe ends
has a small projection; the facer stopper let you select the only pipe to face. Put the facer stopper in
the left or in the right hole to prevent the right or left facing. To face all the pipes put the facer stopper
in the central hole.

Warning!!!: Always check that the speed selector of the drill engine is in position 1 (lower
speed)
g)

h)

Slowly approach the pipes ends towards the facing tool by means of acting on the hydraulic control unit (lever A Table V ) keeping
a value of pressure allowing the facing of the surfaces and avoiding an overload of the drill engine (a too much high pressure could
burnt out the drill engine). When shavings from both sides will appear continuous and homogeneous , the facing operation is
completed.
Put in contact the two pipes ends to be welded and check if the eventual disjunction is within the values of the following table:
Outside diameter
mm
< 400
> 400

Port
mm
0,5
1,0

In case the above values cannot be fulfilled the facing operation must be repeat.

4.4 Inertial pressure measurement
Before begin a welding cycle it is necessary to measure the inertial pressure. This value must be added to the pressure value shown in our
welding tables. The inertial pressure value depends on welding operating conditions (ex.: length and weight of the pipe to drag, general
condition of the machine, ambient temperature, etc.). To measure the inertial pressure follow these steps:
a) Completely open the movable trolley of the machine by means of acting the lever A and take it in position A2
b) By turning the lever F (Hyd. Unit) anticlockwise bring the pressure to zero, checking the pressure gauge
c) Turn clockwise the lever E (Hyd. Unit) until closing
d) Bring the lever A (Hyd. Unit) into position A3 (the trolleys do not move because there is no pressure)
e) By turning clockwise the hand wheel F note the inertial pressure value ( value of pressure need in order to allow the trolley moving ) by
reading it into the pressure gauge

Example on how to calculate the cooling down (t5) time following the DVS NORM
As per drawing above the time T corresponds to wall thickness value X in
mm. To calculate this time (t5 in minutes) please follow the formula below:

T = 6+

10 − 6
⋅ ( x − 4,5)
7 − 4,5

Example:
If you want to calculate the cooling down time for a 6mm wall thickness pipe, you must simply substitute the variable X with the value 6:

T =6+

10 − 6
⋅ (6 − 4,5) = 8,4 min
7 − 4,5

To calculate the other times (t3 and t4) you must use the same principle of linear interpolation.
To obtain the t2 (in seconds) value use the formula below where the variable wt corresponds to the nominal wall thickness

T2 (sec) = 10 ⋅ wt( mm )

6. Welding Table for PE pipes DVS norm version 2207-1
The following tables show the values to be applied during the welding cycle as per previous instructions and graph.
However in order to clarify once again the meaning of these values please kindly note:
t1 =
Time requested for the bead formation to be done with pressure value = P1 + inertial pressure
t2 =
Time requested for the continual heating to be done with pressure value = P2 + inertial pressure
t3 =
Time requested for the change over
t4 =
Time requested for bringing up the pressure at the value of pressure = P1 + inertial pressure
t5 =
time requested for cooling down to be done with pressure value = P1 + inertial pressure
Important: Remember always to add the value checked of inertial pressure to the P1 and P2 values !!!!!!!
