10219/S235 Welded Steel Pipe
EN 10219/S235 Welded Steel Pipe Description
EN10219 welded steel pipe is mainly used in liquid transportation, drainage systems, bridge construction and other fields. Its advantages lie in advanced manufacturing technology and stable and reliable quality. Through strict quality control and testing, it is guaranteed that products meet standard requirements and provide reliable engineering support. European standard seamless pipe S235JR is widely used in petroleum, natural gas, chemical, coal and other industries due to its outstanding strength and corrosion resistance.
The EN 10219 S235 Welded Steel Pipe is a high-quality cold-formed electric resistance welded (ERW) steel tube manufactured in strict accordance with the European Standard EN 10219. This standard specifies the technical delivery conditions for cold-formed welded structural hollow sections of non-alloy and fine grain steels.
As a product conforming to this norm, the S235 pipe is primarily designed for use in structural applications where load-bearing capacity, durability, and precise dimensions are critical. The "S235" designation refers to the minimum yield strength of the steel, which is 235 N/mm² (MPa), ensuring robust mechanical performance suitable for a wide range of engineering projects.
Key Features & Specifications
Standard: EN 10219 (Cold formed welded structural hollow sections of non-alloy and fine grain steels).
Steel Grade: S235JR, S235JRH (commonly used). The "JR" indicates the impact test temperature requirement (20°C).
Manufacturing Process: Cold Forming followed by High-Frequency Electric Resistance Welding (HF-ERW). This process ensures a high-integrity weld seam and a smooth surface finish.
Available Shapes: Circular (CHS), Square (SHS), and Rectangular (RHS).
Surface Condition: Typically supplied in bare, black steel condition. Options for hot-dip galvanizing (HDG) or other protective coatings are available upon request to enhance corrosion resistance.
Tolerance: Complies with the strict dimensional tolerances specified in EN 10219, ensuring consistency and ease of assembly on-site.
Applications
Due to its reliable strength and formability, the EN 10219 S235 welded pipe is widely utilized across various industries:
Construction & Building: Used for columns, beams, trusses, and portal frames in commercial and industrial buildings.
Mechanical Engineering: Ideal for manufacturing machine frames, conveyor systems, and agricultural equipment.
Infrastructure: Applied in bridge construction, highway guardrails, and support structures.
General Fabrication: Suitable for any project requiring lightweight yet strong hollow sections for welding, bolting, or riveting.
Conclusion
The EN 10219 S235 Welded Steel Pipe represents a cost-effective and structurally efficient solution for modern engineering challenges. Its compliance with rigorous European standards guarantees quality, safety, and interoperability, making it a preferred choice for contractors and engineers worldwide seeking reliable structural steel components.
