API 5L X60 line pipe series

API 5L X60 PSL1/PSL2 line pipe is a carbon steel pipe used for oil and natural gas transportation. These PSL1 and PSL2 API 5L X60 Pipes are available in different forms of Seamless Line Pipe and Welded Line Pipe.

API 5L X60 provided by CSC

CSC's API 5L X60 PSL1/PSL2 line pipe grades offer good machinability and excellent welding properties with or without filler metal. CSC offers other API 5L line pipe in various sizes and shapes according to customer specifications.

c. The specified minimum elongation, Af, expressed in percent and rounded to the nearest percent, shall be determined using the following equation:
Where C is 1 940 for calculation using Si units and 625 000 for calculation using USC units
Axc is the applicable tensile test piece cross-sectional area, expressed in square millimeters (square inches) , as follows
– For circular cross-section test pieces, 130mm2 (0.20 in2) for 12.7 mm (0.500 in) and 8.9 mm (.350 in) diameter test pieces; and 65 mm2 (0.10 in2) for 6.4 mm (0.250in) diameter test pieces.
– For full-section test pieces, the lesser of a) 485 mm2 (0.75 in2) 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 (0.10in2)
– For strip test pieces, the lesser of a) 485 mm2 (0.75 in2) 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 (0.10in2)
U is the specified minimum tensile strength, expressed in megapascals (pounds per square inch)
