Luminium PP-R pipe
Performance characteristic:
1. Green, nonpoisonous: This product is the green building materials, can be used in the pure water, drinking water pipeline system.
2. The out layer is PP-R material, middle layer is Aluminium, inner layer is cross-linked PE-X.
3. Corrosion-resistant and forming the dirt; Can avoid the pipeline and form stopping up and water basin, anxiety of the bathtub macula lutea rust mark after the dirt.
4. Able to bear high temperature, high pressure; Under fixed long-term working pressure, the pipeline delivery temperature can be up to 95 degrees Centigrade.
5. Keep energy-conservation warm: Heat conduction coefficient metal 1/200 of pipeline only, used in hot water pipeline keep energy-conservation warm to be dandy.
6. Quality is light: Proportion is only 1/7 of the metal pipeline.
7. The internal and external wall of the products is smooth, fluid obstruction is small, the color and luster is soft, handsome in appearance.
8. Can bury the ground: Can survey out the position of the tube with the metal detector.
9. It is convenient and reliable to install: Adopt hot to is it join to melt, need sets of silk, can finish first piecing join one second, divide into water device is it adopt high-quality copper inlay piece to join, safe and reliable with metal pipe.
10. Have long performance life: The pipeline system is using the life-span of making and being up to more than 50 years normally.

It explains to install:
1. Weld pipe size related heating end head is it get weld plane to assemble, connect, wait to heat the head and reach 260 degrees Centigrade of best temperature;
2. Using the special-purpose cutting knife, cut pipes vertically, the cutter handwheel rotates 30 angles, the cutting knife rotates 1 circle along the round outside the pipe, does not exert oneself too quickly while cutting to the aluminium layer, so as not to influence the aluminum pipe, deform it, the notch should have no burr levelly and smoothly;
3. Clean the welding position of pipes and pipe fittings, prevent sand, dust, etc. From entering, influence the quality of welding;
4. Weld the depth with the mark on the pipe of pencil;
5. Insert the pipe and pipe fittings in the welding device at the same time, heat according to stipulated time, is it heat time see hot to melt technical parameter form to weld;
6. Finish heating, take out pipes and pipe fittings, join immediately, when the pipe cooperates with connection of the pipe fittings, if being position incorrect, the two can do on a small quantity changing for a fixed period of time, but it does not exceed 5 degrees to turn back the angle;
7. Join, must both hands hold pipes and pipe fittings tight, keep enough cooling time, cool back hand can unclamp to certain extent, continue and install the next pipe
