Butt
welding Aluminum-plastic composite pipe
DXPAP2
Junxing PEX-AL-PEX pipe is a five-layer composite pipe that
combines the advantages of a metal and plastic pipe and
eliminates the disadvantages of both materials at the same
time. The aluminum core is absolutely diffusion tight; it
reliably prevents oxygen/gases from permeating into pipe. It
compensates and reduces snap-back forces and heat expansion
with changes of temperature.
Junxing PEX multilayer composite pipe consists of an overlapped
or butt welded aluminum core with an inner and outer layer or
high temperature-resistant polyethylene. All layers are
permanently bonded together by intermediate adhesive layers.
The aluminum thickness for Junxing PEX pipe has been selected
to meet compressive and flexural strength
requirements.
Overlapped welded PEX pipe is co-extruded with one step with
perfect adhesive between inner layer and aluminum, high and
stable pressure resistance, of which welding style is
ultrasonic.
Butt welded PEX pipe is moulding with several steps that is
argon-arc welding style.
The color of PEX pipe is optional.
