    Why Kingbull PVC-U Drainage Pipes and Fittings?

    1. Modern and Scientific Production Management Mode
    Kingbull applies automatic dosing system remotely controlled by computer. It handles the problems that manual dosing often results in high labor cost, material loss and chemical damage to operators. Meanwhile, it improves dosing accuracy and ensuring consistency of product quality.

    We use efficient pneumatic conveying system that replaces the onerous manual works, improving production efficiency. The whole material handling process is completed in closed pipes, thus avoiding dust flying in the workshops and protecting the operators. Material preparation and processing is more centralized and efficient, ensuring higher output.

    2. Specialized PVC-U Pipes Extrusion Equipment and Injection Molds
    Our PVC-U pipe extruder employs self-designed conical twin screw which available in various diameters and lengths. The screws with proper diameters and length-diameter ratios will be used for extruding pipes in different specifications, so as to improve production output and ensure plasticizing quality as well.

    The runner of die head features streamline design without dead angle, and the surface has been electroplated and polished. This avoids material stacking and thereby prevents other problems because of that. Additionally, the die heads used come with the most appropriate compression ratio. It is known that too small compression ratio of die head leads to less density of extruded products and insufficient adhesion of joint line, and over large compression ratio speeds down extrusion and thereby improves cost.

      Pipe fitting molds also come with scientific streamline design which reduces stress concentration and ensures higher impact strength of fittings.

      With advanced subsurface design, the sprue is solid, flat and eye-pleasing, with fully relief of stress and high strength. Reasonable cooling system design assures the dimensional stability of products.

      Mold core is made of stainless steel imported from Germany. It ensures the degree of finish and dimensional accuracy of pipe fittings.

        3. Elaborately Selected Materials and Traceable Management System
        R&D engineers in Kingbull select the raw materials for our PVC drainage pipes and fittings meticulously, so as to ensure the best performance. PVC pipes are mainly composed of PVC resins and stabilizing agent, lubricating agent, modifying agent, filling agent, coloring agent, etc. according to a certain proportion. The selection of each material is conducted regarding the applications and properties of PVC pipes.

        (1) PVC Resins
        We only use the PVC resins from renowned large sized petrochemical corporations. They are sure to offer stable and reliable quality.

        • Primary Particle Aggregate and Integument
        • Primary Particles

        (2) Stabilizing, Lubricating and Modifying Agents
        The stabilizing agents are from domestic famous enterprise and the lubricating and modifying agents are imported. We carry out dynamic rheological test using torque rheometer to differentiate superior and inferior agents.

          (3)Filling Agent
          The biggest filling agent that use in our PVC-U pipes is calcium carbonate which is mainly used to improve pipe's rigidity and hardness and slightly increase heat deflection temperature, thus reducing thermal expansion coefficient, lowering molding shrinkage and enhancing dimensional accuracy.
          Selected calcium carbonate comes with high whiteness and fine and evenly distributed particles. State of the art laser particle sizing instrument and whiteness measuring device are used to ensure the material's stability.

          (4) Impact Modifier
          We use famous brand Chlorinated Polyethylene (CPE) as the PVC impact modifier. And we use muffle furnace and drying oven to strictly control the ash content and volatile matter in the CPE, ensuring the final PVC pipes come with high impact strength.

          (5) Coloring Agent
          According to different purposes, PVC-U pipes and fittings are available in white, gray and many other colors. So coloring agent is indispensably used in the production of this plastic pipes. The most commonly used coloring agents include titanium dioxide and carbon black.

          Kingbull introduces rutile titanium dioxides from large and well-known suppliers. They feature high whiteness, fine grain size, good cladding and superior aging resistance. When added to the PVC pipes, they allow the pipes to resist long time exposure to sun without color changing.

          4. Cutting-Edge Technology and Rigorous Quality Management
          Specific techniques can maximize the performance of PVC products. Technological parameters are closely related to production formula and equipment. A great process condition is corresponding to specific formula and equipment.

          Screw barrel temperature, screw speed, die head pressure and pulling speed are important technological parameters in pipe extrusion; cylinder temperature, nozzle temperature and mold temperature of injection molding machine, plasticizing pressure and injection pressure are important parameters in injection molding of pipe fittings. Relevant technological parameters are made for specific formula and equipment.

          Kingbull's PVC-U drainage pipes have passed the international immersion test in 4L methylene dichloride. This certifies that the pipes come with higher impact strength and better weather resistance.
