API 5L pipeline is the oil, natural gas, and water transmission pipeline specified by American Petroleum Institute, including seamless and welded steel pipes.
API 5L line pipes are available in multiple carbon steel grades, designated as Grade B, X42, X46, X52, X56, X60, X70, and X80, and in PSL1 or PSL2 specification levels. The following is the difference between PSL1 and PSL2 and the introduction of common steel grades.

Advantage of API 5L Seamless Pipeline
1. Help cut down on expenses.
Although more expensive than the welded pipe, this increased ability to withstand pressure allows using pipes that are thinner and lighter,
so the total price is lower.
2. Excellent resistance to cracking forces which can be caused in long pipelines;
3. Sour service suitability and durability;
4. Excellent strength and ability to withstand high-temperature applications;
5. Long service life in any industrial pipeline operation.


Differences between PSL1 & PSL2
NPS | Outside Diameter | Wall Thickness |
CVN impact (Charpy) testing | None required | Required for all grades |
Nondestructive Inspection of Seamless | Only when the purchaser specifies SR4 | SR4 mandatory |
Certification | Certificates when specified per SR15 | Certificates (SR 15.1) mandatory |
Traceability | Traceable only until all tests are passed, unless SR15 is specified | Traceable after completion of tests (SR 15.2) mandatory |
Hydrostatic Test | Required | Required |
Application of API 5L Seamless Tube Common Grades

API 5L Gr.B.Gr.B is the most used steel grade in API 5L, which is used for low-pressure fluid lines and serving different mediums, such as the transmission of oil, natural gas, or water.

API 5L X60/X65.API 5L X60/X65 pipelines are also common grades mostly used in the petroleum and oil and gas industries.

API 5L X42API 5L X42 line pipe is most commonly used in the petroleum industry to transport oil and gas. Onshore, for transporting oil and gas from wellheads to refineries, and offshore, for transporting oil and gas from platforms to onshore terminals.API 5L X42 line pipe is also used in other industries such as the chemical industry, chemical transportation, construction industry, for pipeline construction.

API 5L X52.X52 and X42 have the same purpose, but the impact test of - 20 ° is added to X42.
So it is a higher-strength steel grade than X42 and is typically used in higher-pressure applications.
At present, the demand for API 5L X52 steel pipes in African countries is increasing.
