1, Introduction:
As a kind of high quality and high-performace pipe, the product has a construction of five layers. The inside and ousite layers are made of PPR, tightly bonded with PP-based adhesive to the mid-layer of aluminum core, which is well welded in an overlapping way. Such pipe is a kind of perfect combination of metal pipe and plastic pipe.
2, Advantages
A, Greatly reduced linear expansion coefficient, only 1/4 of that of 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, resistant to UV-rays;
D, Working under higher temperature and higher pressure for cool and hot water system;
E, Easily detected by detector when embedded, owing to the metal layer;
F, Good performance of heat preservation and low heat conduction coefficient of 1.45W/M. K;
G, Smooth and sanitary, being good selection for drinkable water system.
Product introduction of ZHSU PE/PPR-AL-PPR pipe
Properties of ZHSU PAPR plastic composite pipe PAPR Aluminum plastic composite pipe mainly have the following features:
1. Applied for potable water pipeline systems which are hygienic and non-toxic. The aluminum middle layer has a very low linear heal expansion coefficient. The pipe is not only as rigid as metal pipes but is also flexible and pressure-resistant.
2. Corrosion resistance properties prevents encrustation build-up in the pipes thus enabling the free flow of water and eliminating rust that causes stains In tubs and basins.
3. This pipe has high temperature and high pressure resistance and can work under continuous normal working pressure within water temperatures up to
4. Heat preservation and energy saving properties greatly minimizes heat losses during hot water flow. The neat conduction coefficient is 1/200 of metal pipes.
5. Class="f8"5. The pipes are lightweight and the specific gravity is 1/7 of metal pipes. The surface of the inner and outer layer of the pipe Is smooth therefore reduces low resistance.
6. The pipes can be buried underground and are easily found with metal detectors.
7. The hot melt connection machine is used to connect the pipes and fittings. Which makes the installation convenient and reliable. The installation can be finished within a few seconds.
8. The pipes have a long lifespan of up to 50 years or more under normal conditions, convenient and reliable. The installation can be finished within a few seconds.
9. Have an effect of electromagnetic shielding;
10. Can be directly buried under ground, and metal detector can be used to detect position of the pipe;
11. Oxygen would be absolutely isolated due to utilization of aluminum core, thus bacterial reproduction is prevented.
