Detailed Product Description
The PPR-AL-PPR(PE) pipe is five-layer composite pipe that combines the advantages of a metal and common PPR 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.
Note:The color of the pipe is optional.
The preponderant application field of PP-R plastic-al multilayer pipe :
Hot water, potable water system
central air conditioning.
warming by radiator,underfloor heatingsystem
The pipe system outside, like solar energy pipe system.
compress air pipeline system.

advantages:
1) 2/3~4/5 lower coefficient of thermal expansion than common pipe, better anti-creep, same strength as metal pipe, nice installation.
2) High pressure resistance, high shock resistance
3) UV-resistance, long lifespan
4) A healthy environmental protection product (health, no chemical reaction, no oxidation, accordance with GB/T17219-1998 Stardand ) is suitable to be applied in food industry and drinking-water supply.
5) Capability to be buried under ground. And to be detected by metal detector
6) All advantages of common PP-R pipe
Installation:
Outer diameter of the pipes (mm) | Depth of the welding joint | Heating time(s) | Inlaying time(s) | Cooling time |
20 | 14 | 5 | 4 | 2 |
25 | 15 | 7 | 4 | 2 |
32 | 16.5 | 8 | 6 | 4 |
40 | 18 | 12 | 6 | 4 |
50 | 24 | 18 | 6 | 4 |
63 | 26 | 24 | 8 | 6 |
Remark: The heating time should extend 50% and inlaying time should shorten 50% when the temperature in operation environment is lower than 5°C.
