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
