Grade X52 indicates 52000 PSI minimum yield strength and 66000 PSI minimum ultimate tensile strength.
The American Petroleum Institute specification API 5L addresses seamless and welded steel line pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil.
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.
| Grade B | (ASTM A53, A106, A523) | (API 5LR) | (API 5L PSL2) |
|---|---|---|---|
| Minimum Yield Strength: | 35,000 psi | 35,500 | 35,000 psi |
| Maximum Yield Strength: | None | 65,000 psi | |
| Minimum Tensile Strength: | 60,000 psi | 60,200 | 60,000 psi |
| Maximum Tensile Strength: | None | 110,000 psi | |
| Notes: This grade may be used for standard pipe, line pipe or conduit pipe as specified in the various ASTM and API specifications | |||

Usually API 5L X52 PSL2 Pipe are supplied as hot rolled. Only tubes with DN 6 -10, perhaps tubes of other dimensions are supplied as cold drawn and after forming they are heat treated. This is done as per precious agreement. The tube surface meets corresponds to the means of manufacturing.
Tubes are visually straight.
Ends of tubes are smooth, without threads.
From 60.3 diameter beveled according to standards:
DIN, EN – a = 40° – 60°, c = to 2 mm
ASME – a = 75° ± 5°, c = 1,6 ± 0,8 mm
Tubes with diameter up to 1 ½” are marked with label on the bundle. Tubes with larger diameter than 1 ½” are implemented according to directives or upon request.
Line pipes are supplied without temporary protection against corrosion. Upon request it is possible to deliver tubes with agreed upon anticorrosion protection. The tube ends may be enclosed by a plastic plug.
API X Grades – some of the sturdiest pipes and tubing available designed for extreme environments or exceedingly high pressure environments
