Large Diameter Anti-Corrosion Steel Pipe

Why Choose Our Large-Diameter Anti-Corrosion Steel Pipes?

Since its inception, JuMing has been dedicated to the research and development and production of Durable Large Diameter Anti-Corrosion Steel Pipes, with an annual production capacity of 150,000 tons. We possess fully automated coating production lines ranging from Φ325 to Φ3000 mm, and can customize products from DN100 to DN3200.

By employing an integrated preheating, spraying, and curing process, we ensure uniform and stable epoxy resin (EP) or polyethylene (PE) coatings, with an inner coating thickness ≥0.3 mm and an outer coating thickness ≥0.5 mm, significantly extending the service life of the pipes.

All products undergo rigorous factory inspections, including water pressure testing, airtightness testing, and coating continuity testing for each batch, guaranteeing zero-defect delivery. With an intelligent warehousing and logistics system, we can provide reliable bulk supplies and quickly respond to urgent orders. To date, our pipes have been successfully supplied to over 300 municipal and industrial projects in China and exported to Southeast Asia, the Middle East, and other overseas markets.

What are the advantages of our products?

1. Superior Corrosion Resistance

The Quality Large Diameter Anti-Corrosion Steel Pipe features excellent chemical stability in both its inner and outer coatings, resisting corrosion from acids, alkalis, salts, and organic solvents, effectively eliminating common corrosion and scaling problems found in traditional steel pipes.

The coating adhesion meets GB/T 9286 standard Level 1, with an impact strength ≥50 kg·cm, ensuring long-term stable operation without the risk of peeling or delamination.

2. Highly Efficient Fluid Transport

The ultra-smooth inner surface (roughness 0.008 mm) reduces friction loss by more than 30% compared to traditional steel pipes, significantly improving fluid transport efficiency.

The food-grade epoxy resin coating complies with GB/T 120-2016 hygiene standards, suitable for drinking water supply and food processing fluid transport.

3. Excellent Mechanical Strength

Made from high-quality Q235B or Q345B steel, with a yield strength ≥235 MPa, it can withstand working pressures up to 1.6 MPa.

The steel-plastic composite structure gives it significantly higher bending strength than pure plastic pipes, making it ideal for underground, overhead, and other complex installation environments.

4. Long-Term Economic Value

With a service life exceeding 50 years, far surpassing traditional steel pipes (10-15 years), annual maintenance costs can be reduced by up to 70%.

Large Diameter Anti-Corrosion Steel Pipe weighs 40% less than cast iron pipes of the same size, resulting in 25%-30% savings in transportation and installation costs.
