Detailed Information
1. Key Standards and Material Grades
EN 10217-1: Covers non-alloy and fine-grain steel tubes with specified elevated temperature properties. Commonly used grades include P235, P265, and others.
Related Standards: EN 10217 is often referenced alongside other standards such as API 5L, ASTM A106, and GB/T 8163 for applications in oil, gas, and structural piping.
Material Grades: Includes carbon steel grades like 20#, 16Mn, Q235, Q345, and alloyed variants for high-pressure and high-temperature environments.
2. Manufacturing and Technical Specifications
Production Techniques: Tubes under EN 10217 are typically manufactured using hot-rolled or cold-rolled processes, with options for seamless or welded construction depending on the application.
Surface Treatment: Options include paint varnishing, oil coating, or plastic end caps to prevent corrosion during transportation and installation.
Dimensions: Common outer diameters range from 219.1 mm to 3048 mm (8"–160"), with wall thicknesses between 4 mm and 25.4 mm.
3. Applications
EN 10217-compliant pipes are widely used in:
Pressure Systems: Such as boilers, hydraulic systems, and gas transmission.
Structural and Fluid Transport: Including water supply, sewage systems, and oil pipelines.
Industrial Infrastructure: For constructing pipe racks, bridges, and other structural frameworks.
4. Certifications and Compliance
Certifications: EN 10217 pipes often meet additional certifications like API 5L, ISO 9001, and CE, ensuring quality and safety for international markets.
Testing Requirements: Includes hydrostatic testing, ultrasonic inspection, and dimensional tolerance checks (e.g., ±1% for wall thickness).
Summary
EN 10217 steel pipes are critical for high-pressure and structural applications, offering versatility through multiple material grades and manufacturing processes. They are widely adopted in energy, construction, and industrial sectors due to their compliance with rigorous international standards.
