PPR Plastic Composite Pipe

Product Description

1, Introduction:

As a kind of high quality and high-performace pipe, the producthas a construction of five layers. The inside and outside layersare made of PPR, tightly bonded with PP-based adhesive to themid-layer of aluminum core, which is well welded in an overlappingway. Such pipe is a kind of perfect combination of metal pipe andplastic pipe.
2, Advantages
A, Greatly reduced linear expansion coefficient, only 1/4 of thatof PPR which means the composite pipes have stable dimensions.
B, 100% oxygen tightness, suitable for heating system;
C, Improved resistant to impulse under low temperature, resistantto UV-rays;
D, Working under higher temperature and higher pressure for cooland hot water system;
E, Easily detected by detector when embedded, owing to the metallayer;
F, Good performance of heat preservation and low heat conductioncoefficient of 1.45W/M. K;
G, Smooth and sanitary, being good selection for drinkable watersystem.
Product introduction of PE/PPR-AL-PPR pipe
Properties of  PAPR plastic composite pipe PAPR Aluminumplastic composite pipe mainly have the following features:
1. Applied for potable water pipeline systems which are hygienicand non-toxic. The aluminum middle layer has a very low linear healexpansion coefficient. The pipe is not only as rigid as metal pipesbut is also flexible and pressure-resistant.
2. Corrosion resistance properties prevents encrustation build-upin the pipes thus enabling the free flow of water and eliminatingrust that causes stains In tubs and basins.
3. This pipe has high temperature and high pressure resistance andcan work under continuous normal working pressure within watertemperatures up to
4. Heat preservation and energy saving properties greatly minimizesheat losses during hot water flow. The neat conduction coefficientis 1/200 of metal pipes.
5. class="f8"5. The pipes are lightweight and the specific gravityis 1/7 of metal pipes. The surface of the inner and outer layer ofthe pipe Is smooth therefore reduces low resistance.
6. The pipes can be buried underground and are easily found withmetal detectors.
7. The hot melt connection machine is used to connect the pipes andfittings. Which makes the installation convenient and reliable. Theinstallation can be finished within a few seconds.
8. The pipes have a long lifespan of up to 50 years or more undernormal conditions, convenient and reliable. The installation can befinished within a few seconds.
9. Have an effect of electromagnetic shielding;
10. Can be directly buried under ground, and metal detector can beused to detect position of the pipe;
11. Oxygen would be absolutely isolated due to utilization ofaluminum core, thus bacterial reproduction is prevented.
