EN10217 is a European technical standard for welded steel pipes for pressure purposes. It is not a single material, but is divided into several sub-standards according to the application scenarios, which regulate the manufacturing requirements for different materials of steel pipes. The following is the core classification and corresponding material description:
1. Standard system and material classification
Carbon steel material
EN10217-1: Applicable to non-alloy steel pipe, material including Q235B and other carbon steel, used for oil, natural gas and other fluid transport pipelines.
Spiral seam double-sided submerged arc welding process: through the double-sided submerged arc welding technology to ensure the quality of weld seam, smooth surface and good corrosion resistance.
2. material properties and application scenarios
Pressure-bearing capacity:
Carbon steel (Q235B) steel pipe has high strength and stability, suitable for high-pressure fluid transport (such as oil pipelines).
Processing performance:
Stainless steel welded pipe supports customised processing (e.g. cutting, bending) to meet the needs of architectural decoration, machinery manufacturing and other scenarios.
3. supporting process and testing requirements
Manufacturing process:
The welding process needs to comply with the standard provisions (such as submerged arc welding, high frequency welding) to ensure that the weld is free of defects.
Stainless steel tubes need to be solution treated to eliminate stress and enhance the toughness of the material.
Testing standards:
Chemical composition analysis, mechanical properties testing (tensile, hardness) and hydraulic test are mandatory.
Summary: EN10217 is a series of standards for welded steel pipes covering carbon steel (e.g. Q235B) and stainless steel (e.g. 304, 316L), which are broken down by The standard ensures the reliability of steel pipes in terms of pressure, corrosion resistance and other key properties through detailed application scenarios (fluid transport, chemical equipment, etc.) and strict process requirements.
