Suppliers | Stockists | Exporters of Seamless and Welded Pipes & Tubes

Rolf Engg. Solutions Inc is the largest stockist and supplier of API 5l PSL 2 Pipes from Grade B to X120. We stock pipes of Japan, Europe, Korea, China, India origin. We also have stocks of Sour Service, HIC Tested, NACE MR 0175/0103, SSC Tested material.

Our Stock range consists of:

Seamless Pipes - 1/2" to 42"
ERW Pipes - 1/2" to 24"
LSAW Pipes - 20" to 100"
Thickness - Sch 10 to Sch XXS and heavier.

For different environment there will be different requirement for API 5L line Pipes. The PSL 2 Line Pipes contains additional chemical, mechanical properties and testing requirement. This specification covers seamless and welded steel line pipe from grades B through X80. API 5L Line Pipes can be supplied in Normalized condition, Quenched and Tempered Condition and also in Mechanical conditions. If you require PSL 2 pipes means these pipes are used for natural gas pipe or crude oil line pipe where there are high requirements for pipe pressure, pipe anti-corrosion ability, high mechanical strength etc.

We can export and supply

a    Based upon product analysis. For seamless pipe with t > 20,0 mm (0.787 in), the CE limits shall be as agreed. The CEiiw limits apply if C > 0,12 % and the CEpcm limits apply if the C ≤ 0,12 %.
b    For each reduction of 0,01 %  below the specified maximum for C, an increase of 0,05 % above the specified maximum for Mn 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 , Nb + V ≤ 0,06 %.
d    Nb + V + Ti ≤ 0,15 %.
e    Unless otherwise agreed, Cu ≤ 0,50 %; Ni ≤ 0,30 %; Cr ≤ 0,30 %; Mo ≤ 0,15 %.
   Unless otherwise agreed.
g   Unless otherwise agreed, Nb + V + Ti ≤ 0,15 %.
h   Unless otherwise agreed, Cu ≤ 0,50 %; Ni ≤ 0,50 %; Cr ≤ 0,50 %; Mo ≤ 0,50 %.
i    Unless otherwise agreed, Cu ≤ 0,50 %; Ni ≤ 1,00 %; Cr ≤ 0,50 %; Mo ≤ 0,50 %.
j    B ≤ 0,004 %.

k   Unless otherwise agreed, Cu ≤ 0,50 %; Ni ≤ 1,00 %; Cr ≤ 0,55 %; Mo ≤ 0,80 %.
l    For all PSL 2 pipe grades except those to which footnote j already applies, the following applies. Unless otherwise agreed no intentional addition of B is permitted and residual B ≤ 0,001 %.

9.2 Chemical compostion

9.2.2    For PSL 2 pipe with t 25,0 mm (0.984 in) the chemical composition for standard grades shall be as given in Table above and for intermediate grades shall be as agreed, but consistent with those given in Table 

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

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