Product Description

碳钢 拷贝



  • Uniform Structural Strength: The spiral weld ensures more even stress distribution, providing excellent bending and compression resistance.

  • Cost-Effective Production: Compared to straight seam welded pipes, it offers higher material utilization, making it suitable for bulk supply of long-distance pipelines.

  • Comprehensive Standard Compliance: Meets international standards such as API 5L, EN 10217, and GB/T 9711.

Suitable for oil and gas transportation, water treatment pipelines, pile pipes, structural supports, and municipal pipeline networks. We support custom lengths, beveling, anti-corrosion coatings, third-party inspections, and provide complete quality documentation and export-related services.
