28-Inch Large Diameter Carbon Steel Pipe
Product Overview
The 28-inch (DN700) large-diameter carbon steel pipe is engineered for energy transmission, heavy-duty structures, and industrial projects. With a 711mm outer diameter and exceptional pressure-bearing capacity, this pipe is the ideal choice for oil, gas, municipal water supply, and large-scale steel structure applications. Manufactured in strict compliance with API 5L and ASTM A106 international standards, it delivers reliable quality and outstanding performance.
Key Advantages
1. Large Diameter for High-Efficiency Transmission
The 28-inch diameter ensures high flow capacity with minimal resistance, significantly improving oil, gas, and fluid transmission efficiency. It substantially reduces pumping energy consumption and operating costs for long-distance pipelines.
2. High-Strength Material for Durability
Made of high-quality carbon steel (Grade B), with a minimum yield strength of 240MPa, offering excellent compression and deformation resistance. Whether buried underground or installed at height, it reliably withstands demanding operating conditions.
3. Multiple Anti-Corrosion Options for Extended Service Life
A variety of anti-corrosion coating options are available, including PE, 3PP, and FBE, effectively resisting corrosion from soil, seawater, and chemical media. This extends the pipeline's service life and reduces maintenance frequency.
4. Full Certifications for Quality Assurance
The product is available with internationally recognized certifications including API 5L, ABS, BV, DNV, and LR, ensuring product quality meets the requirements of global engineering projects.
