PVDF
PVDF (polyvinylidene
difluoride) is a
fluorinated and semi-
crystalline techno-
polymer containing
59% of its weight in
fluorine. This material
is obtained through
the polymerization
of vinylidene fluoride.
It boasts exceptional
mechanical,
physical and
chemical resistance,
guaranteeing
excellent thermal
stability up to 140° C.
The FIP PVDF line uses Solef® PVDF resins, manufactured by SOLVAY for
industrial applications, for the production of pipes, fittings and valves made
by extrusion and injection moulding. The entire line is made using Solef®
resins by SOLVAY S.A. classified according to ASTM D 3222 and complying
with the requirements of ISO 10931.
Thanks to its high purity and exceptional performance, PVDF is the best
alternative to metal materials, and is extensively used in industrial appli-
cations (chemical, oil, pharmaceutical, pulp and paper, electronic, etc.),
whether in process systems or otherwise.
Among the most important properties and advantages of Solef® PVDF, the
following are particularly worthy of note:
• Excellent chemical resistance:
the use of Solef® resin, a vinylidene fluoride polymer, ensures excellent
resistance to corrosion and abrasion when conveying highly aggressive
chemicals. PVDF is basically inert to most inorganic acids and bases, or-
ganic acids, aromatic and aliphatic hydrocarbons, alcohols and halogenat-
ed solvents. However, it is not recommended for use with fluorine, amines,
ketones and oleum (sulfuric acid with sulfur trioxide).
• Excellent thermal stability:
PVDF maintains its characteristics unchanged in a temperature range
between -40° C and +140° C. PVDF pipes are particularly suitable in all
applications requiring high operating temperatures, very low levels of fluid
contamination and high resistance to ageing due to atmospheric agents
and UV radiation. The material's excellent mechanical properties are re-
tained even at high temperatures.
• Fire resistance:
Solef® resins guarantee excellent fire resistance without the need for flame
retardants (Limit Oxygen Index, LOI = 44%). In case of combustion, smoke
emissions are moderated. Solef® PVDF resins are classified UL-94, class
V-O.
• Purity:
Solef® PVDF resin is an extremely pure polymer that does not contain
stabilizers, plasticizers, lubricants or flame retardants. As a result, it is the
ideal material for conveying ultra-pure water and chemicals, ensuring the
non-contamination of the conveyed fluid. As it is physiologically non-toxic,
it is suitable for conveying fluids and food products.
• High abrasion resistance:
according to the Taber Abrasion Test (in which the weight loss of a
material is measured after being exposed to an abrasive wheel for 1000
cycles), PVDF is the most resistant thermoplastic material (CS-10 Load 1kg
- Weight Loss / 1000 cycles = 5-10 mg.)

SOCKET WELDING
INSTRUCTIONS
Fig. 1
Hot socket welding involves fusing the pipe in the fitting's socket. The joint is made
by simultaneously fusing the male and female surfaces by means of special manual
or automatic heating devices. These devices, in their simplest form, are composed of
a heating plate on which a series of heating bushes are mounted. The devices comes
with an appropriate heating system complete with an automatic temperature con-
troller. No additional materials are required for this type of welding. Socket welding
does not affect the chemical resistance of the PVDF, nor does it influence the inner
pressure resistance of the assembled pipes and fittings. The pipe to be welded must
be cut, chamfered and peeled if necessary. The external surface of the pipe and the
internal surface of the fitting must be carefully cleaned, and the external surfaces of
the pipe and fitting can be marked with a reference notch to eliminate the risk of in-
advertent rotation while the joint is setting. The next step is to insert the pipe in the
female bush and the fitting in the male bush and hold them in position for the neces-
sary heating time; when this time has elapsed, the parts must be quickly removed
from the bushes and then the pipe inserted into the fitting to the full previously de-
termined insertion length, ensuring the reference notches are correctly aligned. The
two elements must be supported for approximately 15 seconds after initial insertion
and then left to cool at ambient temperature without using forced air flows or water
immersion.
Procedure for hot socket welding
The method described below is applicable only when creating thermal socket welds
that call for the use of manual type welding equipment (fig. 1). The use of automatic
and semi-automatic appliances, which are particularly suitable for diameters greater
than 63 mm, calls for a specific working knowledge of the welding tool. In this case,
adhere strictly to the tool manufacturer's instructions
1) Select the female bushes and the male bushes of the required diameters, insert
them and secure them to the heating plate (fig. 2).
2) Carefully clean the contact surfaces (fig. 3). When choosing the type of liquid
detergent, use recommended products supplied by specialist producers: trichlo-
roethane, chlorothene, ethyl alcohol and isopropyl alcohol are all suitable.
3) Set the temperature of the heating tool. To form the joint correctly, the tempera-
ture should be set between 250° C and 270° C.
4) When the appliance has reached the preset temperature, check the temperature
of the heating plate using a fast acting thermoprobe.
5) Cut the pipe at right angles, chamfer it and if necessary peel it out (fig. 4-5). The
peeling diameter and length and the chamfer depth must correspond to the val-
ues shown in the table named “Pipe peeling and chamfer dimensions”. The cham-
fering process can be performed either after peeling or concurrently with this
operation, using special calibrated tools.

Fig. 3 Fig. 4 Fig. 5

6) Mark the pipe with the insertion length L1 (fig. 6), referring to the values indicat-
ed in the table named “Pipe insertion length” and checking that any peeling has
been machined to the entire length shown in the table.
7) Mark a longitudinal reference line on the outside of the pipe and the fitting to
prevent the two parts from rotating while the joint is being made (fig. 7).
8) Clean the fitting and pipe from any traces of oil or dust on the weld surfaces (fig. 8).
9) After having checked that the surface temperature of the heating plate has sta-
bilized at the required value, insert the pipe into the female bush and the fitting
in the male bush (fig. 9). Holding the parts inserted in the two bushes (fitting
inserted to limit stop, pipe inserted up to the end of the peeling length), wait for
the minimum heating time shown in the table named “Heating, welding and cool-
ing times”.
10) When the minimum heating time has elapsed, quickly remove the elements
from the bushes and fit the pipe into the fitting for the entire insertion length L1
marked previously (fig. 10). Do not turn the pipe in the fitting; ensure the longitu-
dinal reference marks are perfectly aligned (fig. 11).
11) Hold the jointed elements for the welding time shown in the table named
“Heating, welding and cooling times” and then leave them to cool slowly at
ambient temperature without using forced air flows or water immersion.
12) When the internal and external surfaces have cooled sufficiently, pressurize the
plant for the joint hydraulic test.

Supporting PVDF pipes conveying liquids of density other than 1 g/cm3.
If the liquid being conveyed has a density other than 1 g/cm3, the distance L must be
multiplied by the factors in the table.
INSTALLATION
The installation of thermoplastic pipe systems requires the use of support clips to pre-
vent flexing and the resulting mechanical stresses.
The distance between the clips depends on the pipe material, SDR, surface temperature
and the density of the conveyed fluid.
Before installing the clips, check the distances reported in the table below, as provided
for by guidelines DVS 2210-01 for water pipes.
