API 5L X52 PSL2 line pipe belongs to the medium-grade steel pipe in the API 5L standard. The "X52" in its name represents the minimum yield strength of the pipe body at room temperature of 52ksi (about 355MPa). This characteristic enables it to withstand the complex stress generated during oil and gas transportation and ensure the long-term stable operation of the pipeline system.

FAQ
What is the difference between API 5L X42 and X52?
API 5L X42 is the most commonly used carbon steel pipe grade in fabrication, processing and construction applications. API 5L X52 steel is a steel grade commonly used in the petroleum industry, it is a higher strength steel grade than X42 and is often used in high pressure applications.
What does X52 pipe mean?
X52 pipe is a type of API 5L steel pipe that is commonly used in the oil and gas industry. The designation "X52" indicates the pipe's minimum yield strength, which is 52,000 psi (pounds per square inch).
What is the strength of X52 material?
Grade X52 indicates 52000 PSI minimum yield strength and 66000 PSI minimum ultimate tensile strength.
