The "XINFENG" brand PP-R pipe
is one of the latest pipes resulting from European advanced
technology of gos. Its raw materials, a propylene random copolymer,
are imported from Europe. The quality of our PP-R pipes is entirely
up to the standard of DIN8077/8078 of Germany.
Featured by excellent cleanness, cost effectiveness,
applicability and advantage in safety, it is considered as the
optimal pipe material for cold and hot water system, water purifying
engineering, underground heating system for wooden floor, chemical
pipe works and so on.

Feature:
- Sanitary and innoxious. This kind of
product belongs to the green building materials, so they can be
applied to the pure drinking water pipeline systems.
- Thermal insulating: Under the set
long-time continuous working pressure, the water temperature
transmitted by the pipes can be as high as 95°C.
- Corrosion resistance and scale free: Both
the outside and inside surfaces are smooth, so the resisting force
of flowing water is low. Blockage due to water scales and yellow
stains on water basins and fish tanks can be avoided.
- Heat insulating and energy saving: The
coefficient of heat conductivity is only 0.5% over that of the metal
pipes. The heat insulating and energy saving effects are very good
when the pipes are utilized for hot water pipes.
- Light weight and high strength: The
specific gravity is only one-eighth over that of the metal pipes.
The pressure resisting test strength is over 5Mpa(50kg/cm2),so the
products have good ductility and impact resistance.
- Convenient and reliable installation:
Hot-fusion junctions are adopted. One junction can be finished in
several seconds. The pipes are connected with the metal tubes and
water utensils with copper-inlaid joints, so are reliable.
- Long service life: The service life of the
pipes can last 50-odd years under regular operating
conditions.
