API 5L Data Sheet
Scope
This standard specifies the technical delivery conditions for steel pipes (casing, tubing, and pup joints), coupling stock, coupling material, and accessory material.For products covered by this standard, the sizes, masses, and wall thicknesses, as well as grades and applicable end-finishes, are provided.
MANUFACTURE
The weld seam shall be heat treated after welding to a minimum of 1,600 °F, or otherwise processed, to ensure that no untempered martensite remains.
Mechanical Specifications (Grade X52M, PSL2)
| Yield Strength | Tensile Strength | Yield-to-Tensile Ratio | Hydrostatic Test Pressure |
|---|---|---|---|
| Minimum 52‚200 psi (360 MPa) | Minimum 66‚700 psi (460 MPa) | Maximum 0.93 | 2‚500 psi (17.2 MPa) |
HYDROSTATIC AND ULTRA SONIC TESTING
Hydrostatic inspection test pressures for plain-end pipe are listed in section 9.12 of the latest revision API 5CT specification. Test pressures shall be maintained for a minimum of seven seconds.Ultra Sonic testing of the weld seam as required by the latest revision of API 5CT specification is done immediately following the welding process and ahead of the annealing process.
