EN 10216-2 Seamless Carbon and Alloy Steel Tubes

The EN 10216-2 standard specifies the requirements for seamless carbon and alloy steel tubes for high-pressure applications in industries such as oil and gas, chemical processing, and power generation. The tubes have a nominal diameter of 10-660mm and wall thickness up to 100mm, made from carbon steel, low-alloy steel, or alloy steel. The standard ensures quality through mechanical properties, chemical composition, dimensional tolerances, and surface finish. Manufacturers must undergo testing and inspection to ensure compliance. Benefits include high strength-to-weight ratio, resistance to corrosion and erosion, excellent weldability, versatility, and compliance with international standards.
