Thomsun General Trading LLC are the leading and the most professional ppr pipe manufacturers and pipe clamps suppliers and other electrical mechanical products distributor in the United Arab Emirates (UAE).
1, the connection between
the PPR pipe and fitting should be welding. For the metal pipe connection we can
use flange connection, but to connect with water applicator must be used with
metal insert pipe fittings.
2, We should use professional pipe cutter to cut
the pipe, which will guarantee smooth incision. 3, Be sure to clean up the PPR pipe and fitting
welding parts to prevent sand and dust
to damage the joint quality. 4, We should heating the ppr pipe and fittings
according to the regulation time when welding the pipe and fittings. 5, Insert the pipe and fittings into identified
depth to the welding tools without rotating. 6, After the completion of the heating,
immediately join the pipes and pipe fittings for connection. You can adjust the
pipe and fitting in a certain time if you find the position is wrong during the
connection. 7. After the connection, we should wait for a
cooling time to use the pipe and fittings. Connected pipes and fittings should be done on
the wall or the ground with color paint to mark the location of the pipeline,
so that you can avoid damaged by redecorate.
Do PPR pipes resist to acid and alkaline? The acidity and alkaline of our drinking water is expressed in in pH in chemistry, pH = 7 to
neutral, pH < 7 as acidity, pH > 7 is alkaline, One simple method to
measure the PH degree of acid and alkali is to use pH indicator paper. You can test the PH by yourself to experience of drinking water PH value if you have that paper in hand.
The world health organization did not mention clear standard for the drinking water quality. Our GB5749 drinking water hygiene pH indicator is in 6.5 to 8.5; GB17324 bottled drinking water pH indicator is in 5.0 to 7.0. These indicators and the developed countries, in line with the standard of water can be rest assured to drink.
plastics are chemically inert, so Ppr pipe is resistant to general acidicmedium.
Due to the chemical
inertness of PPR pipe, it has a strong resistance to alcohol, acid, alkali and
low boiling point hydrocarbon solvent. At indoor temperature, ppr materials are
difficult to be dissolved in most organic solvents. And when in Water-based reagent like acid or alkali, the possibility of environmental stress cracking damage
is very small. but when with chlorinated organic compounds, strong oxidizer,
liquid hydrocarbon contact, it is easy to cause surface crack or swelling, because
nonpolar compounds can be easily absorbed by polypropylene.
PPR pipes can resist general acidic medium, but not strong acid and strong base.
Therefore, if ppr pipes are for general residential use, no need to worry
about the resistance issue.
