ASTM A139 S235 J0 Spiral Steel Pipes
One of the main advantages of S235 J0 spiral steel pipe is its flexibility in diameter and wall thickness specifications. This allows for greater manufacturing adaptability, especially in the production of high-grade, thick-walled pipes. In addition, the technology is particularly effective at producing thick-walled pipes of small and medium diameters, outperforming other existing methods.

| a. The deoxidation method is designated as follows:FF: Fully killed steel containing nitrogen binding elements in amounts sufficient to bind available nitrogen (e.g. min. 0,020 % total Al or 0,015 % soluble Al).b. The maximum value for nitrogen does not apply if the chemical composition shows a minimum total Al content of 0,020 % with a minimum Al/N ratio of 2:1, or if sufficient other N-binding elements are present. The N-binding elements shall be recorded in the Inspection Document. | ||||||||
