Cross-linked
polyethylene (PEX) pipes used in hot water supply are
required for high mechanical strength and high creep
resistance at high temperature. PEX-a pipes which are made
by peroxide cross-linking have better performance, such as
creep resistance and thermal shock resistance than the
pipes made by other cross-kinking
method.
Features of Pipe
Production
Line:
1)High
strength material made crank-rod structure, ensuring
machine working reliability and
durability. ABB brand
converter to control material feeding; directly adjust on
main PLC system High quality
stainless steel material made
hopper Cylinder
driven by AC motor, China top quality brand; connected by
high ware resistance
belt.
2)Special
designed tip and die mould for PEX-a pipe making; Processed
and manufactured by imported CNC machinery to ensure the
precision degree, and produced pipe diameter and thickness
accuracy. Tip heating
system is special designed, with conduction oil. Oil
temperature is set on main PLC.And with pressure displace
gauge, and also control
valves. Due to PEXa
material speciality, tip and die mould surfaces are special
treated, to reduce friction
force.
3)Cooling tank
and haul-off machine are designed as in integration, saving
space and easy to
operate. Cooling tank
body material is made high stainless
steel Haul-off
machine driven by AC motor, with ABB brand converter;
Separate control panel for operation
convenience. Using SICK
brand encoder, and AUTONICS brand length metering system,
with alarm and length auto marking to get exact required
coil length.
4)Polish rod
type traversing system; easy to
operate Coil reel
structure is very simple; inner coil size is fixed, which
is designed as per customer requirement or factory
standard.
EVOH Oxygen Barrier Pipe
Production
Line:
Finished PEX-a
pipe can be coated with EVOH oxygen barrier and other
protection layer, by another separate extrusion line, to
get a 3 layer PEXa EVOH oxygen barrier pipe or 5 layer PEXa
EVOH oxygen barrier
pipes. The three
layer PEX-a oxygen barrier pipe strucrues are: PEXa pipe,
adhesive layer, and outer EVOH oxygen barrier layer.
However the five PEXa oxygen barrier pipe structures are:
inner PEX-a pipe, adhesive layer, Middle EVOH oxygen
barrier pipe, Adhesive layer, and outer PE protection
layer.
