API 5L PSL2 X46 line pipe is a medium-strength carbon steel pipeline product specially designed for conveying gas, water, and oil in the natural gas and oil industries. It belongs to the mainstream "X" series grades of the API 5L pipeline steel specification, covering standard grades including A25, A, B and X42, X46, X52, X56, X60, X65, X70, X80. The two-digit number following the "X" represents the Minimum Yield Strength (in thousands of psi) of the pipe grade. The minimum yield strength of API 5L PSL2 X46 pipes is 46000 psi, featuring stable mechanical performance and excellent weldability, suitable for low and medium-pressure oil and gas transmission projects.
