PPR-AL-PPR Pipes

PPR-AL-PPR composite pipe is composite pipe of five layers, inside and outside layers of which are made of PP-R, tightly bonded with mel adhesive to the mid-layer of aluminum core which is longitudinally welded in a butt welded or overlap-welded way, this kind of pipe is the perfect union of metal and the plastic ones.

Advantages

*Compared with the ppr plastic pipe, the ppr composite pipe has the same strength, reluctant to retain former shapes

*Smooth inner surface of the pipe reduces resistance to the fluids. The ability to conduct water is 30% more efficient

*Super properties of high temperature, high pressure and corrosion resistance

*Good property of heat preservation, heat conduction coefficient is 0.45 W/m.k, which is much less than metal pipes and it can save insulation materials outside the pipe

*Easy to cut and install. It can be connected with special fittings instead of screw fittings; small diameter pipes can be rolled and packaged. Once bent in order than many directional parts such as elbow s or angles are no longer recessing very convenient to install, much time and labor cost can be saved

 *Life pan of the composite pipe is more than 50 years

Application

1) Potable water For cold and warm water installations

2) For rainwater utilization systems

3) For compressed air plants

4) For swimming pool facilities

5) For solar plants

6) For agriculture and horticulture

7) Heating pipes for residential housing

8) For industry

Connection Way

1.)Incisions and lacerations

Can easily use a fine-tooth saw or pipe cut machine cutting,Cutting the pipe to ensure that the discharge port is flat and perpendicular to the axis. After cutting should be outer pipe orifice chamfering,The slope should be 15 ° -20 °

2.)To try socket, crossed

Before bonding should socket oral inserted,and inserted into the surface to draw inserted into the socket depth marking

3.)Clean-up face

Before bonding pipes and fittings should strictly check the nozzle and the surface of the socket.After Check no pollution,With a clean dry cloth or cotton yarn to wipe clean the inside and outside of the socket

4.)Brushing adhesive

The socket should use clean and free of dirt brush dipped in adhesive quickly brushing the jack.first coated socket brushing, then coated jack.Evenly brushing, shall not leak spreads and shall appropriate to the amount of adhesive

5.) Connection

Find the positive direction of the socket alignment socket quickly inserted, pressing hard, Insertion depth to the chain line and reaches the root of the mouthpiece,and guarantee the straightness of the Order of the interface and the interface to the correct position,the socket should once completed.When inserted into the 1/2 socket should be a little rotation, but should not exceed 1/4 turn,then inserted into the end,No further rotation

6.) Maintenance of the socket

After completion of the bonding process,should be clean the residue of excess adhesive,

Bonding site within one hour should not be affected by external force and shall not pass water within 24 hours.
