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. |

Hydrostatic Test
Each length of pipe shall be tested by the manufacturer to a hydrostatic pressure that will produce in the pipe wall a stress of not less than 60% of the specified minimum yield strength at room temperature. The pressure shall be determined by the following equation:
P=2St/D
Permissible Variations In Weights and Dimensions
Each length of pipe shall be weighed separately and its weight shall not vary more than 10% over or 5.5% under its theoretical weight, calculated using its length and its weight per unit length
The outside diameter shall not vary more than ±1% from the specified nominal outside diameter
Wall thickness at any point shall not more than 12.5% under the specified wall thickness
One of the standout features of S235 J0 Spiral Steel Tube is its versatility. Available in round, square and rectangular forms, the product can be customized to fit the specific needs of any project.
