Introduction of EN10297 E470 seamless carbon steel pipe
E470 alloy round steel pipe is a high-strength alloy steel pipe with excellent mechanical properties and durability. Due to its seamless process, E470 seamless steel pipe has the advantage of no welds, making its structure more uniform and stable, with stronger pressure resistance, and is suitable for engineering situations that withstand high pressure.
The outer diameter of hot-rolled E470 European standard steel pipes produced by GNEE is generally 22-760mm, and the wall thickness is 2.5-200mm. The outer diameter of cold-rolled seamless steel pipes can be up to 6mm, the wall thickness can be up to 0.25mm, and the outer diameter of thin-walled pipes can be up to 5mm wall thickness. Less than 0.25mm, cold rolling has higher dimensional accuracy than hot rolling.
Applications of EN 10297-1 E470 Seamless circular steel tubes
E470 alloy steel pipe can be used in pipeline systems, structural supports and mechanical components in petroleum, chemical, electric power, machinery manufacturing and other industries.
