Table ---Chemical  composition for PSL 2 pipe with t ≤ 25,0 mm (0.984 in) (Continued) 

a    Based upon product analysis. For seamless pipe with t > 20,0 mm (0.787 in), the carbon equivalent limits shall be as agreed. The CEiiw limits apply if the carbon mass fraction is greater than 0,12 % and the CEpcm limits apply if the carbon mass fraction is less than or equal  to 0,12 %.

b    For each reduction of 0,01 %  below the specified maximum for carbon, an increase of 0,05 % above the specified maximum for manganese is permissible, up to a maximum of  1,65 % for grades ≥ L245 or B, but ≤ L360 or X52; up to a maximum of 1,75 % for grades >L360 or  X52, but < L485  or X70; up to a maximum of 2,00 % for grades ≥L485 or X70, but ≤ L555 or X80; and up to a maximum of 2,20 % for grades >L555 or X80.

c    Unless otherwise agreed , the sum of the niobium and vanadium concentrations shall be ≤ 0,06 %.

d    The sum of the niobium, vanadium and titanium concentrations shall be ≤ 0,15 %.

e    Unless otherwise agreed, 0,50 % maximum for copper, 0,30 % maximum for nickel, 0,30 % maximum for chromium and 0,15 % maximum for molybdenum.

   Unless otherwise agreed.

g   Unless otherwise agreed, the sum of the niobium, vanadium and titanium concentrations shall be ≤ 0,15 %.

h   Unless otherwise agreed, 0,50 % maximum for copper, 0,50 % maximum for Nickel, 0,50 % maximum for chromium and 0,50 % maximum for molybdenum.

i    Unless otherwise agreed,  0,50 % maximum for copper, 1,00 % maximum for nickel,  0,50 % maximum for chromium and 0,50 % maximum for molybdenum.

j    0,004 % maximum for boron.

Chemical compostion

9.2.4    For PSL 2 pipe with a product analysis carbon mass fraction equal to or less than 0,12 %, the carbon equivalent, CEpcm, shall be determined using Equation (2):            
                                 

where the symbols for the chemical elements represent the mass fraction in percent (see Table 5).

.If the heat analysis for boron is less than 0,000 5 % then it is not necessary for the product analysis to include boron, and the boron content may be considered to be zero for the CEpcm calculation.
  
9.2.5     For PSL 2 pipe with a product analysis carbon mass fraction greater than 0,12 % the carbon  equivalent, CEllw shall be determined using Equation (3):           

                                


where the symbols for the chemical elements represent the mass fraction in percent (see Table  5).

NOTE: A derogation from the ISO rules for the presentation of chemical equations has been granted for Equations (2) and (3) in deference to their longstanding use in the industry.
