PP-R aluminum-plastic stable composite pipe has five-storey
structure, the mid-layer is welding aluminum tubes, the inside and
outside tube is PP-R Plastic, both the inside and outside tube
between with the aluminum is PP-Based hot melt adhesive, the middle
layer of aluminum alloy pipe is the core framework for the entire
pipeline. This structure combines the rigid metal pipe and health
and sealing plastic pipe perfectly.
Aluminum oxide layer resistance, health aseptic
The middle layer of aluminum isolates the external air,
infiltrating the external oxygen barrier pipe, inhibiting the
bacterial survival in the breeding pipeline. It is used to ensure
the health of the water in the pipe and to prevent secondary
pollution invisible.
Bears small influence of ’expansion in hot and reduction in cold ’,
it has a good Anti-distortion performance.
The expansion properties of PP-R aluminum-plastic stable composite
pipe is close to metallic materials, and has no apparent ’expansion
in hot and reduction in cold ’when install and apply to use, the
outside is more straight and attractive. It has obvious
advantagesin high-temperature, hot water, heating the area, outdoor
pipes installed applications.
