EN10210 Seamless Steel Pipe Core Information Sorting

1. Standard definition and technical requirements

Applicable materials: The EN10210 standard mainly targets non alloy and fine-grained structural steel hot formed seamless steel pipes (hollow materials), covering materials such as S235JR, S355JR, S355J2H, etc., emphasizing the specifications of welding processes and compressive performance.

Key requirements:

Welding control: It is necessary to ensure the cleanliness of the weld seam, compatibility of the welding material, and verify the quality through ultrasonic or radiographic testing.

Compression test: The yield strength and tensile strength are verified through tensile testing, and compression testing is required in special scenarios to ensure stability under axial pressure.

2. Product specifications and market supply

Mainstream specifications:

Outer diameter/wall thickness: Common specifications include φ 10.2~φ 356mm, wall thickness 1.6~20mm, and customized special-shaped pipes (such as square pipes and elliptical pipes).

Material Expansion: Manufacturers have launched materials such as SS317L, A36, S355J2H, etc., to adapt to different industrial scenarios.

3. Application areas and industry demands

Energy and Industry:

Boilers and pressure vessels: used for high-temperature water pipes, smoke pipes, air preheating pipes, etc., must meet the requirements of high temperature resistance and corrosion resistance.

Petrochemical and ship engineering: High specification materials (such as TP304, TP316L) are suitable for corrosive environments and improve equipment life.

Architecture and Machinery: As a structural support material, it is applied in scenarios such as bridges and heavy machinery frames.

4. International Trade and Certification

Export certification: Chinese manufacturers have been certified according to standards such as EN10210 and ASTM A500, expanding into markets in Europe, America, and Southeast Asia.

Environmental Trends: The EU is promoting low-carbon production technologies, such as hydrogen recovery processes, which affect carbon emission control in seamless steel pipe manufacturing processes.
