Yongte's Production Line Solves the Production Challenges of Large-Diameter PVC Pipes, Boosting Industry Efficiency
With the continuous advancement of municipal engineering and water conservancy construction, the demand for large-diameter PVC pipes continues to rise. These pipes are not only corrosion-resistant but also have relatively controllable overall costs, making them the preferred choice for many projects. However, on the production side, many companies are often troubled by several long-standing problems—especially with large-diameter PVC pipes exceeding 500 mm in diameter. During production, issues such as unstable molding, uneven wall thickness, and high energy consumption are common, directly impacting product qualification rates and production costs.
To address these pain points, Yongte Plastic Machinery, leveraging its technological accumulation in the plastic machinery manufacturing field, has launched a PVC pipe production line specifically designed for large-diameter pipe production. Targeted optimizations have been made from extrusion, sizing, to the control system, and significant results have already been achieved in practical applications.
In actual production, traditional equipment frequently encounters problems: uneven material plasticization leads to easy pipe cracking; inaccurate control of ovality and thickness during molding results in unstable product quality, high energy consumption, and high noise levels. Furthermore, the complexity of operation and high dependence on workers place significant pressure on many small and medium-sized enterprises.
To fundamentally improve this situation, Yongte's PVC pipe production line utilizes a customized high-torque twin-screw extruder in the extrusion stage. Combined with a specialized barrel and screw design, this ensures smoother material transport and more uniform plasticization. The production line is also equipped with a high-precision intelligent temperature control module, which, through multi-stage independent temperature control, keeps barrel temperature fluctuations within ±1℃, ensuring a stable melt state and laying a solid foundation for subsequent molding.
In the molding and sizing stages, which determine pipe quality, this PVC pipe production line innovatively employs "vacuum internal pressure composite sizing" technology. Combined with a large-diameter specialized mold and an intelligent pressure sensing system, it can monitor and automatically adjust key parameters in real time. This allows the pipe's ellipticity to be stably controlled within 0.5%, and the wall thickness deviation to be significantly reduced to approximately ±2%, resulting in a substantial improvement in product qualification rate. In terms of energy conservation, thanks to technologies such as variable frequency speed control of motors and waste heat recovery, the energy consumption per unit product of this PVC pipe production line has decreased by 15%–20%, and operating noise is controlled below 75 decibels, better meeting current environmental protection production requirements.
To further lower the barrier to entry, Yongte has equipped this PVC pipe production line with a user-friendly industrial control system. Operators can monitor and adjust key parameters such as extrusion speed and temperature in real time through a central control console. The system can also automatically record production data and generate reports, greatly facilitating quality traceability and production management. Furthermore, this PVC pipe production line supports remote operation and maintenance services. Yongte's technical team can diagnose equipment status in real time via the cloud, quickly respond to faults, effectively reduce downtime, and ensure continuous and stable production operation.
The head of a pipeline company in Shandong shared their experience: "Previously, we used traditional equipment to produce DN1200 sewage pipes, with a product qualification rate of only around 70%, and energy costs per ton were more than 200 yuan higher. Since switching to Yongte's PVC pipe production line, the qualification rate has stabilized at over 98%, energy consumption has significantly decreased, operation is much easier, and overall production capacity has increased significantly." Similar feedback is not uncommon. Currently, Yongte's PVC pipe production lines are in use in dozens of companies nationwide, covering multiple fields such as municipal drainage and farmland irrigation, continuously creating tangible benefits for customers.
Looking to the future, Yongte Plastics Machinery stated that it will continue to focus on the real needs of the industry, advancing research and development in areas such as new material adaptation and intelligent control, and continuously optimizing the performance and applicability of its PVC pipe production lines. With continued investment in infrastructure construction, the market prospects for large-diameter PVC pipes are broad. Yongte, with its solid technological accumulation and pragmatic product improvements, is helping customers reduce costs and increase efficiency, and is also winning more development opportunities for itself in the competitive plastics machinery industry.
