Water Treatment
Compared to traditional metal or other plastic valves, our UPVC valves offer distinct competitive edges:
| Advantage | Specific Content | Customer Value |
| Excellent Corrosion Resistance | No electrochemical corrosion; exceptional tolerance to acids, alkalis, salts, and other chemical media; no rust or scaling. | Reduces maintenance frequency, extends service life, lowers replacement costs. |
| Outstanding Chemical Properties | Tensile strength ≥40 MPa; high impact strength; superior elongation at break; adaptable to slight ground settlement. | Resists impact/deformation, reduces post-installation pipeline damage risks. |
| High-efficiency Conveyance | Smooth inner wall (friction coefficient 0.009, vs. steel pipe’s 0.017); minimal fluid resistance. | Improves medium transport efficiency, reduces energy consumption for pumps/power equipment. |
| Lightweight & Easy Installation | Density 1.4 g/cm³ (~1/5 of steel, 1/6 of cast iron); supports rapid connections. | Lowers labor/equipment costs and shortens project timelines. |
| Hygienic & Eco-friendly | Lead-free production; no leaching of heavy metals/harmful substances; complies with GB/T 10002.1-2006 hygiene standards. | Ensures drinking water safety; suitable for food/medical clean environments. |
| Ultra-long Service Life | Buried: >50 years; exposed (with UV inhibitors): >30 years. | One-time investment for long-term benefits; reduces lifecycle costs. |
| Cost-effectiveness | Controllable material costs + low maintenance; >40% overall savings vs. stainless steel pipes. | Balances quality and budget; enhances ROI. |

High-quality raw materials are the cornerstone of high-quality pipes. We consistently adhere to top industry standards in selecting raw materials, ensuring the first line of defense for product performance:
1. Raw Material Sources and Standards
Core raw materials are sourced from globally renowned chemical companies (such as XX Chemical and XX Group). We use virgin UPVC resin with a purity of ≥99.5%, rejecting recycled or regenerated materials.
All raw materials are tested by authoritative organizations such as SGS and ISO, and comply with GB/T 5761-2018, "Suspension-Processed General-Purpose Polyvinyl Chloride Resin," ensuring uniform resin molecular weight distribution and an impurity content of ≤0.1%.
2. Scientifically Formulated Auxiliary Materials
We use imported antioxidants, stabilizers, UV inhibitors, and other auxiliary materials, with strictly controlled additive dosage (for example, stabilizer addition is accurately maintained at 0.3%-0.5%). This ensures the product's resistance to aging and degradation while preventing the release of harmful substances.
Virgin UPVC The high purity of the resin and the scientific ratio of the auxiliary materials directly determine the corrosion resistance, mechanical strength and sanitary safety of the pipeline.
