PPR-FB-PPR pipe

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.

◆Advantages:  

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

> Higher strength and stability of dimension.

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

> Improved resistant to impulse under low temperature.

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

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

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

◆Applications: 

> Distribution for cool and hot water;

> Duct for drinkable water system;

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

> Pipes for heating and cooling settings in solar energy system;

> Connecting pipe for air conditioners.
