With abundant experience, we warmly welcome you to buy high quality 4-inch rigid polyvinyl chloride utility pipeline for sale here from our factory. Also, pricelist and free sample are available.
4-inch Rigid Polyvinyl Chloride Utility Pipeline, with its high cost-effectiveness, corrosion resistance, and ease of installation, has become the primary choice for water supply and drainage, agricultural irrigation, municipal engineering, and industrial fluid transportation. As a medium to large-sized PVC pipe, 4-inch Rigid Polyvinyl Chloride Utility Pipeline avoids the limitations of insufficient flow rate in small-diameter pipes while overcoming the cumbersome installation issues of large-diameter pipes. Whether for residential sewage, municipal drainage, agricultural irrigation, or industrial transportation, 4-inch Rigid Polyvinyl Chloride Utility Pipeline maintains stable performance. As a global supplier of 4-inch Rigid Polyvinyl Chloride Utility Pipeline, we always prioritize customer requirements and provide products with consistent quality, earning the recognition and trust of global buyers.
Our 4-inch Rigid Polyvinyl Chloride Utility Pipelines are made from high-purity raw materials, using advanced production equipment and a rigorous production process. We control product quality from the source, ensuring that every pipe leaving the factory meets international standards. During production, we employ advanced extrusion molding technology, and our fully automated production line achieves complete automation from raw material mixing to finished product delivery, further guaranteeing the precision of our 4-inch Rigid Polyvinyl Chloride Utility Pipeline specifications. The detailed production process is as follows:
Raw material preparation:
High-purity PVC resin and environmentally friendly additives are mixed in a precise ratio. First, premix at 80-100℃ to evenly coat the resin with the additives. Then, heat to 110-130℃ for hot mixing. Finally, discharge the material at below 40℃ after cooling to avoid premature plasticization of the resin and ensure uniform mixing and stable performance of the raw materials;
Extrusion Molding:
The mixed raw materials are fed into a conical twin-screw extruder to ensure full plasticization. Segmented temperature control is implemented during extrusion. The die employs a streamlined flow channel design to reduce material stagnation and ensure uniform wall thickness and standard outer diameter;
Cooling and Shaping:
A combination of vacuum shaping chamber and spray cooling is used, employing a gradient cooling method to prevent internal stress and brittleness caused by excessively rapid cooling. The cooled pipes have high dimensional accuracy, with outer diameter error controlled within ±0.5mm and wall thickness error within ±0.3mm;
Traction and Cutting:
The fully automated traction machine synchronizes the traction speed with the extrusion speed and maintains moderate traction tension. A rotary saw blade is used for cutting, resulting in a clean, burr-free cut with a length error controlled within ±5mm, facilitating subsequent construction;
Flaring process:
To meet the requirements of socket connection, the pipe end is flared, with the flaring ratio controlled at 1.05-1.10 to ensure stable socket size and stronger sealing performance during connection;
Finished product inspection:
After each pipe is completed, it will undergo comprehensive finished product inspection to ensure the pass rate before leaving the factory.
