Unobjectionable
by hygiene: All the installation pieces related to drinking water
are subject to DIN 1988 T2 in the food subctance and food area.The hygiene
feature of SPK pipes and fittings emanates from Polypropilene Co-polymer
non-color , taste, and odor, containing no poisonous or canserogene
additives threatening especially the human health.
Sound
insulation: our pipes and fittings have a sound installation value
peculiar to them.This feature provides a preventing impact of the flows
and current noise to transmit to the nearby or next pipe pieces.Therefore,
they are more practical compared to metal pipe installations.
Operating
conditions:
-
In 20ºC cold
water, 20 atü
-
In 95ºC hot
water, 10 atü
Utilization
areas:
-
As column
pipes in multi-storey buildings ,
-
In every type
of hot and cold water installations,
-
In central
heating installations ,
-
In pneumatic
installations,
- In the
industry.
Chemical resistance: PPRC is
resistant to many solvents up to 60ºC.They create swelling effect from
halogenized hydrocarbons and some oils and wax.The swelling is mild up to
30ºC.It has limited or very low resistance to such powerful oxidizing
substances as nitrous acid,ozone,foamed sulphuric acid,hydrogen peroxide
or halogen.In determining the resistance to chemical substances,the test
saples are submerged into the test substances without mechanical stress ,
and then they are tested for swelling, weight loss and shrinking
qualities.
Physiological qualities:
PPRC is physiologically accepted in line with regulatory provisions
related to consumption substances, and its additives are in conformity
with the current VII.Recommendation of the Federal Health Department of
Berlin by type, quantity and pureness,and therefore it has been accepted
physiologically.
Resistance against UV rays:
In installed
state, pipes made from PPRC used in cold and hot water utilities are not
exposed to UV rays.A stabilizer is added to the pipes in order for them
tos tay in outdoors for six months.As in the SPK pipes, the transportation
and storage is recommend in their original packing.
Shock effect: pipes made of
Polipropilen Random Co-polimer are conforming to the requirements in DIN
8078 Section 3.5 related to shock resistance test (under 0ºC ).Its
vulnerability to shocks increases under temperatures below the freezing
point.In general ,this situation applies to all types of Polipropilen
pipes.Against shocks, throwing out the pipes or pipe couplings from
vehicles or similar practices should be avoided.
Quality and reliability:
pipes and fittings have TSE quality certificates from the Turkish
Institute of Standarts.TS 9937 Polipropilen pipes- General purpose quality
specifications; TS 10595 Polipropilenden pipes- dimensions; TS 11451
Polipropilenden pipes-Quality specifications for hot water and floor
heating systems; and TS 11755 Polipropilen pipe coupling pieces.SPK pipes
and fittings are produced in our country under Turkish-German
cooperation.Any failures arising out of material defects will be redressed
by the mnufacturer company. |
