TECHNICAL DATA OF API 5L PSL 2 PIPE FOR SOUR SERVICE Chemical composition API 5L PSL 2 pipe for sour service Altotal = 0.060 %; N < 0.012 %; AI/N > 2:1 (not applicable to titanium-killed or titanium-treated steel); Cu s 0.35 % (if agreed, Cus 0.10 %); Ni ≤ 0.30 %; Cr ≤ 0.30 %; Mo ≤ 0.15 %; B ≤ 0.0005 %. d For Welded pipe where calcium is intentionally added, unless otherwise agreed, Ca/S ≥ 1.5 if S > 0.0015 %; for SMLS and welded pipe, Ca ≤ 0.006 %. Af = C_^xc 0.2 U0.9 where is 1940 for calculations using SI units and 625,000 for calculations using USC units; C Axc is the applicable tensile test piece cross-sectional area, expressed in square millimeters (square inches) as follows: 1) for circular cross-section test pieces, 130 mm2 (0.20 in.2) for 12.7 mm (0.500 in.) and 8.9 mm (0.350 in.) diameter test pieces, and 65 mm2 (0.10 in.2) for 6.4 mm (0.250 in.) diameter test pieces; 2) for full-section test pieces, the lesser of a) 485 mm2 (0.75 in.2) and b) the cross-sectional area of the test piece, derived using the specified outside diameter and the specified wall thickness of the pipe, rounded to the nearest 10 mm2 (0.01 in.2); 3) for strip test pieces, the lesser of a) 485 mm2 (0.75 in.2) and b) the cross-sectional area of the test piece, derived using the specified width of the test piece and the specified wall thickness of the pipe, rounded to the nearest 10 mm2 (0.01 in.2); U is the specified minimum tensile strength, expressed in megapascals (pounds per square inch). CVN absorbed energy requirement for pipe body of PSL 2 pipe Strip Ultrasonic Testing HYDROGEN INDUCED CRACKING REQUIREMENT FOR API 5L PSL 2 PIPE FOR SOUR SERVICE: Acceptance Criteria: · Crack Sensitivity Ratio (CSR): ≤ 15% · Crack Length Ratio (CLR): ≤ 15% · Crack Thickness Ratio (CTR): ≤ 5% Sulfide Stress Cracking (SSC) Test requirement for API 5L PSL 2 pipe for sour service: Acceptance Criteria: No failure or cracking under specified test conditions. Vickers Hardness test requirement for API 5L PSL 2 pipe for sour service: Acceptance Criteria: Maximum hardness 22HRC or 250 HV10 required on weld, HAZ and base metal. Seam Normalizing: Seam normalizing is performed to improve the microstructure and mechanical properties of the weld zone, ensuring uniformity and reducing the risk of corrosion. Non-destructive testing: Additionally, non-destructive tests such as eddy current, ultrasonic testing, magnetic particle inspection, and visual inspection are performed as per API 5L Annexure K to verify pipe Quality. Marking: After the pipe meets all testing requirements, it is marked with the following information AL JAZEERA STEEL PRODUCTS CO.
