Specification

Standards

EN 10217:

Specifies welded steel tubes for pressure purposes (e.g., steam, gas, water). It covers various steel grades and manufacturing methods (e.g., ERW, submerged arc welding) for pipes used in industrial, power, and building applications.

EN 10255:
Focuses on carbon steel tubes for general purposes (e.g., structural, mechanical, fencing). It includes seamless and welded tubes with lower pressure requirements than EN 10217, emphasizing dimensional accuracy and surface quality.

Nominal Diameter (DN): 

Ranges from DN10 (10.2 mm OD) to DN600 (610 mm OD), with DN15-DN300 common for structural use.

Wall Thickness (WT): 

For hot-finished pipes, WT ranges 2.3 mm-40 mm with ±12.5% tolerance; cold-finished pipes have WT 1.5 mm-12 mm with ±10% tolerance.

Straightness:

≤1 mm/m for cold-finished pipes, ensuring easy installation in structural frameworks.

End Finish:

Plain ends (standard) or beveled ends (for welding), with squareness tolerance ≤1% of OD.

Applications

EN 10217:

Steam pipelines in power plants.
Oil and gas processing (low-to-medium pressure).
Building services (e.g., heating systems).

EN 10255:

Fencing, handrails, and structural supports.
Machinery frames and agricultural equipment.
Water drainage systems.

Product Type:

Seamless and welded carbon steel pipes/tubes, covering both hot-finished and cold-finished options.

Steel Grade:

S235JR, S275JR, S275J0, S275J2, S355JR, S355J0, S355J2, with varying strength levels.

Manufacturing Process:

Seamless (hot-rolled or cold-drawn) and welded (electric-resistance welded or furnace-butt welded).

Performance Advantages:

Dual Utility: Suitable for both pressure applications (water, steam, gas conveyance) and structural uses (frames, supports).
Cost-Effective: Carbon steel composition balances performance and affordability, ideal for bulk industrial use.
Versatility in Grades: Grade B provides higher strength for demanding pressure systems, while Grade A suits general-purpose needs.
Corrosion Resistance: Galvanized variants offer enhanced protection against rust in humid or outdoor environments.

Application Scenarios

Plumbing and water supply systems.
Steam and hot water pipelines in industrial facilities.
Oil and gas distribution lines (low to medium pressure).
Structural frameworks in construction and machinery.
Fire sprinkler systems and mechanical tubing.
