API 5L GR B have PSL1 and PSL2,PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.
Grades covered by this specification are A25, A, B and "X" Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.
API 5L covers welded and seamless pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.
