EN 10216 is a European standard for seamless steel tubes designed for pressure purposes, such as boilers, heat exchangers, and pipelines. It covers various grades of non-alloy and alloy steels, including P195, P235, and P265, tailored for high-temperature and high-pressure applications. These pipes undergo strict testing for mechanical properties, chemical composition, and non-destructive examination to ensure reliability and safety.
EN 10216 tubes are widely used in power plants, petrochemical industries, and refineries, offering excellent strength, corrosion resistance, and performance under extreme conditions. The standard ensures compliance with European quality and safety requirements.
EN 10216 specifies technical delivery conditions for seamless steel tubes used in pressure applications. It is divided into parts covering non-alloy, alloy, fine grain, low-temperature, and stainless steel tubes, each tailored for specific operational requirements.
The standard includes various material grades, such as P195, P235, 16Mo3, 13CrMo4-5, P275NL1, and 1.4401, depending on the part. These grades are designed for different temperature and pressure conditions, ensuring suitability for diverse industrial applications.
Each grade has specific chemical composition limits. For example, P235 (EN 10216-1) has ≤0.16% carbon, while 16Mo3 (EN 10216-2) includes 0.25%-0.35% molybdenum. Stainless steel grades like 1.4401 (EN 10216-5) contain chromium and nickel for corrosion resistance.
Mechanical properties vary by grade. P235 offers a tensile strength of 360-480 MPa, while 16Mo3 provides 450-600 MPa. Stainless steel 1.4401 achieves 500-700 MPa tensile strength and ≥40% elongation, ensuring durability and performance under pressure.
EN 10216 seamless tubes offer high strength, excellent corrosion resistance, and superior durability. Their seamless construction ensures uniformity, making them ideal for high-pressure and high-temperature applications in demanding industries.
These tubes are widely used in oil and gas, power generation, and chemical industries. They are essential for transporting fluids and gases under extreme conditions, ensuring safety and efficiency in critical operations.
