Detailed Description

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°C 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: > 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°C 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. ◆Specification data sheet: Outer Dia.(mm) Wall Thickness & tolerance(mm) S4 S3.2 S2.5 20 2.3+0.4 2.8+0.4 3.4+0.5 25 2.8+0.4 3.5+0.5 4.2+2.6 32 3.6+0.5 4.4+0.6 5.4+0.7 40 4.5+0.6 5.5+0.7 50 5.6+0.7 6.9+0.8 63 7.1+0.9 8.6+1.0 75 8.4+1.0 10.3+1.2
