    PPR Hot and Cold Water Pipes

    Kingbull is your trusted supplier of PPR hot and cold water pipes and fittings. Our PP-R pipes for hot and cold water supply are the random copolymer of propylene and ethylene made using advanced gas polymerization process. It makes about 5% ethylene in the molecular chain of PP random copolymer, with approximately 140℃ melting point, 130℃ vicat softening point, 270kj/cm2 tensile strength and 8kg.cm/cm impact strength.

    Although our PPR pipes have slightly lower impact strength than PP-B, they come with the best combination property due to excellent resistance to long-term creep. To illustrate, they can be surely used for 50 years in hot water at a temperature of less than 70℃. Therefore, they are ideal for the hot and cold water piping system in buildings.

    Applications
    The PPR hot and cold water pipes are widely used for industrial and civilian hot and cold water piping system as well as heating system.

    PP-R Tool

    PPR die head comes with large taper that is convenient for heat fusion. Teflon coating is applied to avoid sticking of material in welding.
    Our PPR welding machine requires a moderate temperature for welding, which is at 260±10℃.

    Why Kingbull PP-R Pipes and Fittings?
    1. Superior Raw Materials
    Kingbull’s PP-R pipes and fittings are made using the premium imported materials from Borealis AG, KPIC, etc. or domestic materials from Yanshan Petrochemical. These materials are free from any addition of reclaimed materials, with national standard GB17219compliant sanitary performance and stable quality.

    The melt flow rate (MFR) of the raw materials from which Kingbull PPR pipes and fittings are made is within 0.2-0.35g/10min (230℃, 2.16Kg). International standard≤0.5g/10min. (See table 1 for the physical properties of PPR pipe materials)

    2. Cutting-Edge Technology
    Kingbull cooperates with universities to continuously improve and update PP-R pipes production techniques.
    1) By means of improvement of dies, materials and process, the production speed is increased to 18m/min, and molten plastic stays for a very short time in the extrusion machine, thus ensuring less loss of performance.
    2) PPR pipes and fittings are brittle at low temperature. To handle this, we use unique process and formula to remarkably improve the low temperature impact resistance of our PPR pipes.
    3) With scientific cooling and shaping process, we make our PPR water pipes approved in 8760 hours continuous testing.

    3. Advanced Production Equipment
    1) Our extruder comes with BM barrier screw which ensures excellent solid-liquid separation and plasticizing effect, small extrusion output, pressure and temperature fluctuation, great exhaust performance and stable quality of molten plastics. Equipped with KIV forced feeding system, it features fast extruding speed. This ensures that the molten materials stay in the extrusion heads for a very short time, therefore maintaining less loss of performance.

    2) Scientific die head design assures the pipes of good appearance as well as superior performance. Rational compression ratio and straight section length of the die head ensure enough pressure which is able to avoid cracking of molten materials and serious expansion after extrusion, and make the pipes glossy and stable in size.
    3) Unique sizing and cooling system; It comes with a special pre-cooling structure that makes the freshly extruded pipe tightly fit to the sizing die and thereby leads to stable pipe size. Meanwhile, using water lubricating and jacket water cooling method as well as unique sizing method, the system provides accurate sizing, with small friction, fast cooling and high efficiency, not only ensuring the size stability and roundness of pipes in high speed production, but also offering high crystallinity of PP random copolymer and eliminating concentration of stress.
    4) Laser diameter measuring instrument is used to test the outer diameter of pipes. It accounts for a high dimensional stability.
    5) A high speed PPR pipe cutter imported from Italy ensures rapid, chip free cutting, ensuring flat and smooth end face and preventing notch stress concentration after cutting.
    6) We build a top class laboratory where we introduce a complete set of testing equipment including hydrostatic tester, MFR testing instrument, analyzer differential scanning calorimetry (DSC) analyzer, electronic tensile testing machine, Izod impact testing machine, etc.
