EN 10210 Seamless Pipe Manufacturer

EN 10210 is a European standard for hot-finished seamless and welded structural steel hollow sections, including pipes. These pipes are made from non-alloy and fine-grain steels, offering excellent strength, durability, and weldability. Commonly used grades include S235, S275, and S355, tailored for structural applications in construction, infrastructure, and engineering.

EN 10210 pipes undergo rigorous testing to ensure mechanical properties, dimensional accuracy, and surface quality. They are ideal for load-bearing structures, such as bridges, buildings, and industrial frameworks, providing reliable performance and compliance with European safety and quality standards.

Structural Steel Pipes

Standard Grades of EN 10210 pipes

EN 10210 specifies hot-finished hollow structural steel tubes in non-alloy and fine-grain steel grades. The standard is divided into two main parts: EN 10210-1 for technical requirements and EN 10210-2 for dimensional specifications.

Material Grades of EN 10210 pipes

Non-alloy steel grades include S235JRH, S275J0H, S275J2H, S355J0H, S355J2H, and S355K2H. Fine-grain steel grades are S275NH, S275NLH, S355NH, S355NLH, S420NH, S420NLH, S460NH, and S460NLH.

Chemical Composition of EN 10210 pipes

For non-alloy steel S235JRH, the chemical composition includes: C ≤0.17%, Si ≤0.20%, Mn ≤1.40%, P ≤0.040%, S ≤0.040%, N ≤0.009%. Fine-grain steels have similar elements with different maximum limits, such as S355NH with C ≤0.20%, Si ≤0.55%, Mn ≤1.60%, P ≤0.035%, S ≤0.035%.

Mechanical Properties of EN 10210 pipes

Non-alloy steel S235JRH has a minimum yield strength of 235 MPa, tensile strength of 360-510 MPa, and elongation of 26%. Fine-grain steel S355NH has a minimum yield strength of 355 MPa, tensile strength of 510-680 MPa, and elongation of 22%. Impact energy values vary by grade and temperature.

Advantages of EN 10210 Seamless Steel Pipe

EN 10210 seamless steel pipes offer several key advantages. They are known for their uniform mechanical properties, high ductility, and resistance to fracture, making them suitable for demanding applications. These pipes also exhibit improved buckling strength and dimensional stability, ensuring consistent performance during fabrication and installation. Additionally, they have excellent fire resistance and are fully killed steel, which enhances their weldability and durability.

Applications of EN 10210 Seamless Steel Pipe

EN 10210 seamless steel pipes are widely used in structural engineering for buildings, bridges, and mechanical equipment due to their high strength and weldability. They are also used in hydraulic systems for high-pressure fluid transmission and in the oil and gas industry for pipeline systems. These pipes are suitable for applications requiring high strength and durability, such as in heavy machinery frames, crane booms, and industrial equipment supports.
