In-depth analysis of Jiangsu Xinrong PVC-O pipe equipment

I. Core equipment parameters and technological breakthroughs

1. Production specifications and performance optimization

Jiangsu Xinrongplas Machinery's PVC-O production line can achieve full-size coverage of Ø110-Ø630mm, with material grades of 315-500. Under the same pressure level, the wall thickness is reduced by more than 50% compared with traditional PVC-U pipes, material consumption is significantly reduced, and water delivery capacity is increased by 30%.

The parallel twin-screw extruder is adopted, and the support structure die head design reduces the extrusion power by 15%, while achieving the PN25 level pressure bearing capacity (≥2.5MPa). The impact resistance of the pipe at -20℃ is still better than the normal temperature index of PVC-U pipe.

2. Process precision and intelligent control

The vacuum shaping system integrates three-level independent closed-loop water circulation, the temperature fluctuation is controlled at ±0.5℃, the pipe ovality error is ≤0.3%, and the axial thickness deviation is stable at ±0.05mm (in line with ISO 16422 standard).

The dynamic wall thickness compensation technology combined with the intelligent temperature control module can achieve the precise adjustment of the temperature gradient of the extrusion section ±1.5℃, the plasticization uniformity of the material is increased to 98%, and the waste generation rate is controlled below 0.8%.

II. Production efficiency and cost advantages

One-step process innovation: Compared with the traditional two-step process, the production line occupies 40% less area, the power consumption is reduced by 28%, and the labor cost is saved by 35%.

Energy consumption optimization: The low-temperature extrusion die supports the processing range of 130-145℃, and with the heat recovery system, the comprehensive energy consumption is reduced by 22% compared with the industry average. 

Material performance leap: Through the biaxial orientation process, the bursting pressure of PVC-O pipes is ≥5.0MPa (DN800 specification), the ring stiffness reaches SN16 level, and it can withstand the soil pressure of 15 meters buried depth. The service life is expected to exceed 100 years.

III. Application scenarios and international certification

Diversified applications: The products cover municipal water supply, mine drainage, agricultural irrigation and other fields. The DN600 grade pipes have passed the German 10bar water hammer pressure test, and the connection sealing meets the EN 17176 standard.

‌International certification upgrade: The production line has passed the 2 million pulse pressure test required by the new ISO 16422:2025 regulations, and the sealing ring adopts a steel skeleton full-cover structure (metal contact water content ≤0.0005%).

Extreme working conditions adaptation: Wear-resistant pipes developed for mining scenarios, interlayer bonding strength ≥ 15N/mm², wear resistance index ≤ 80mm³ (ASTM D4060 standard), suitable for deep sea and highly corrosive environments.

IV. Capacity layout and technology outlook

Production base: Zhangjiagang 60,000 square meters manufacturing base has an annual production capacity of 20 million US dollars, supports customized production line development, and shortens the order delivery cycle to 45 days.

Technical reserves: DN800+ ultra-large diameter one-step production line is being developed, and the target axial stretching rate is increased to 1.5m/min. It is expected to complete industrial verification in 2026. 

Market expectations: In 2025, the global PVC-O equipment market size will exceed US$5.2 billion. Jiangsu Xinrong is expected to occupy more than 25% of the domestic market share with its technological advantages.
