• Our ductile iron pipes and fittings are produced in accordance with ISO 2531, EN 545, EN 598, AWWA C151, and GB/T 13295 — ensuring full compliance with global technical and safety benchmarks.

2. Rigorous Quality Control

• Utilizing advanced procedures such as centrifugal casting, spectrochemical analysis, hydrostatic testing, and CNC inspection, each product undergoes strict quality checks—pipes failing to meet standards are destroyed, not shipped.

3. Factory-Direct Pricing

• By manufacturing in our 600-million RMB, 300-acre foundry, we eliminate distributors—delivering unmatched wholesale pricing on all pipe sizes from DN 80 to DN 2600.

4. OEM Customization

• We offer custom diameters, lengths, coatings (zinc, epoxy, polyurethane), linings (cement mortar, epoxy ceramic, polyurethane), and joint types (push-on, restrained, flanged) — tailored to your specifications and project requirements.

5. Proven Mechanical Strength & Durability

• Our products demonstrate tensile strength ≥ 420 MPa, yield ≥ 300 MPa, with spheroidal graphite microstructure and flexibility that absorbs stress—even under surge conditions.

• Coated or cement-lined pipes show 100+ years of lifespan, boasting superior corrosion resistance and longevity.

6. Global Delivery & Sustainability

• Centrifugal casting ensures uniform wall thickness and quality. We support global logistics for fast delivery, and our products are recyclable and eco-conscious, working toward greener infrastructure solutions.
