Pipe & Fitting Systems
Plastic
Pipes and fittings are made of Polypropylene Random Copolymer (PPRC)
Type 3 having thermoplastic properties, and produced by by
copolymerisation of propylene with ethylene.
The
raw material has a high molecular weight, low crystal, high
temperature stabilization and has higher resistance against
temperature and pressure conditions than other similar materials.
It
is suitable for conveying cold and hot water as required by
applicable standards and various fluids defined in the TS 11448, ISO
7471.
The
whole range is manufactured in accordance with International
standards regulations.
The Plastic Pipes are certified by the following:
In
addition to the TSE standards, The Plastic Pipes have the ISO 9001
" Quality Assurance Systems Certificate".
The
Plastic Pipes
-
Do
not accumulate lime, resist puncture.
-
Provides
insulation against electricity, and are a real insulator. They
are also chemically inactive, and resistant against acidic or
alkaline substances they may contact. They are made of a raw
material named PPRC Type 3 which fulfills the requirements
specified in the TS 11448 standard.
-
Have
internal and external surfaces that are resistant to corrosion.
-
Have
internal surfaces that are smooth, homogeneous and nonporous,
and do not scale up with the accumulation of foreign substances.
-
Do
not allow moss and bacterial growth.
-
Meet
the instructions issued by the Turkish Ministry of Health, and
certified by the Department of Hygiene to be suitable for
potable water installations.
-
Have
a higher linear thermal expansion coefficient than that of the
metals.
-
Have
operation pressure of 20 bar at 20 ?C and 10 bar 65 ?C, with a
minimum life of 100 years under suitable conditions.
-
Under
normal conditions, can be used for temperatures up to 70-95 ?C.
They are not water absorbing, and highly moist environments.
-
Do
not emit noise under high flow rates and pressures.
-
Do
not need special insulation when they come into contact with
construction materials such as cement or lime.
-
Are
light, so that they can be easily installed and transported.
-
Are
economic in terms of labor and time.
-
The
PLASTIC PIPES ARE RANGING FROM 20 mm TO 75 mm are MANUFACTURED
WITH THE ASSURANCE AND QUALITY GUARANTEE.
Operation
Requirements
Main
values that determine the behavior of all plastic materials are
stated below;
The
relation between the values stated above is shown on
the graphic.
Usage
of The Curves On The Graph
After
having determined the desired usage time of pipe (e.g.: 20 years)
and the operation temperature (e.g.: 80 ºC), the intersection
point of the vertical line that shows the usage time and the curve
shows the permitted pressure value (?= sigma) for the temperature.

Operation pressure is calculated with the formula stated below:
P = (20*S*?)/(D-S) = (20*3.4*2.5)/(20-3.4) = 10.2 bar
This result shows the maximum resistance in a given time. In order
to find the max. operation pressure, the value of the max.
resistance should be divided by safety factor (f=1.5).
Maximum operation pressure:
Pe max = Pmax/f = 10.2/1.5 = 6.8 bar
