PPR-FB-PPR PIPE

The structure of the JUNXING PPR-FB-PPR pipes incorporates three layers: the inner and the outer polypropylene (PPR) layers filled with special additives and PPR-to-PPR middle fiberglass layer.

The outer layer is made of PPR-copolymer which can be easily treated during conventional pipe welding. It contains special agent additives making the pipe ultraviolet-resistant.

The second, middle layer of the pipes is formed by composite compounds consisting of PPR-copolymer and FB-fiberglass. Such composition provides for improving all technical features of the pipes including mechanical strength and resistance against exposure to high and low environmental temperatures.

Features

1. Linear expandability coefficient α≤ 0.5 x 10 – 4 m/m. ℃, only 1/3 of general PP-R, so it completely settles down the flexibility puzzle of plastic pipe;

2. Reinforce the rigidity and prevent the pipe from dropping, reduce the numbers of fixed points and total cost of project;

3. Improve the static pressure and hydraulic pressure resistance, under the same working condition, the endurable pressure of composite pipe is more 25% than that of the general PP-R with same specification. Improve the safety coefficient of piping and make the working life longer under the general designed vibration force;

4. High temperature resistance, energy conversation, it can be long-term used below 90℃ under the proper pressure in hot water system;

5. Convenient execute melting insertion connection with general PP-R pipe;

6. Settle down oxygen permeability problem, the interior surface directly contact water is sanitary, non-toxic and good sealing property.

Advantages:

1.Greatly reduced linear expansion coefficient, 30% of that of PP-R, which is close to that of the stable composite pipes.

2.Higher strength and stability of dimension.

3. Greatly improved resistant to pressure, it can bear 25% more pressure load than PP-R under the same service condition.

4.Improved resistant to impulse under low temperature.

5. Excellent resistance to high temperature. It can be used in 90℃ for long term.

6.Socket fusion connection with PP-R fittings, credible and convenient.

7. Smooth and sanitary, being good selection for drinkable water system.

Applications:

1. Distribution for cool and hot water;

2. Duct for drinkable water system;

3. Pipes for kinds of high-temperature and low-temperature heating system;

4.Pipes for heating and cooling settings in solar energy system;

5.Connecting pipe for air conditioners.
