PE water supply pipe Feature
¡ñ
Innocuous, hygiene
The material of pipe is
innocuous, it is belong to healthy construction
material, non corrosion,
can¡¯t collect
dirty, it improves the water quality in the
pipe network efficiently¡£
¡ñ
Anti-corrosion
Polyethylene is inert
material, expert few strong oxidant, it can
withstand corrosion of
varieties of chemical
medium, therefore,the pipe has the feature of no
electric chemistry
corrosion,in addition,
the corrosion-proof coat is not needed.
¡ñ
Non-leakage
Polyethylene pipe mainly adopts
the thermal casting connection or electrocasting
connection,
has the good capability of
withstanding the pressure of water hammer,
thermo-weld joint
integrated with the pipe as
well as resistance capability to ground motion
and terminal load,
which can improve much for
the safety and reliability of water supply.
¡ñ
Low flowing resistance
Absolute roughness k
of inner wall of polyethylene pipe is not more
than 0.01mm£¬and the new
steel pipe and
nodular graphite pipe k is >0.06mm, it is
good for reducing the energy
consumption of
water supply¡£
¡ñ Strong toughness
The
material of polyethylene pipe for water supply
has the feature of strong
toughness,
elongation at break usually
exceeds 500%, with strong adaptability to the
pipe base unbalance
subsiding, it is the pie
that has the good shocking resistance
property.
¡ñ Fine flexibility
Due to the
flexibility, polyethylene pipe can be rolled, it
can be supplied with longer length,
to reduce
the use of joints and pipe fittings and be good
for increasing this material economic
value
to pipeline project.
¡ñ Superior anti-rapid
breaking property.
Polyethylene pipe has
advantages like fine capability
of resisting the rapid crack passing,
superior and scratching and obvious
performance of anti environment stress
breaking¡£
¡ñ Long service life
The safety
service life of polyethylene pressure pipe is
more than 50 years.
¡ñ Reclaimable
The
polyethylene material can be recycled,even if it
is burned£¬it can¡¯t bring the material to
pollute the
environment. |
