Product Description
API 5L X60 line pipe is mainly used in the oil and natural gas industry for conveying oil, gas, and water. It is produced from hot-rolled coil or plate with high compressive strength, high low-temperature toughness, and excellent welding performance. The X60 grade designation indicates a minimum yield strength of 60,000 psi, about 414 MPa, and the pipe corresponds to L415 in ISO 3183 notation.
Mechanical Properties
X60 pipe has a minimum yield strength of 414 MPa (60,000 psi) and a minimum tensile strength of 517 MPa (75,000 psi). The material is supplied in normalized, thermomechanically rolled, or quenched and tempered condition depending on the specification level and application, with PSL2 requiring mandatory Charpy impact testing for guaranteed toughness.
End Designs
Welding ends are beveled to an angle of 30 degrees with a root face of 1/16 inch according to ANSI B16.25, forming a V groove with an included angle of 60 degrees and a root opening of 1/16 inch. Plain or straight ends are also available, and threaded ends with or without coupling are supplied per API Spec 5B where required.
Ordering Information
When requesting a quotation, provide the title and standard, quantity in pieces, meters, or tons, size with NPS, schedule or wall thickness, and length, PSL level, grade, manufacturing process (seamless or welded), surface finish, end finish, marking requirements, protective coatings and linings such as 3LPE or FBE, and whether sour service compliance is required.
Applications
X60 line pipe is used in oil and gas gathering and transmission lines, water injection systems, and general pipeline service where medium-to-high pressure and good toughness are required. It is a common grade for onshore transmission pipelines and can be supplied with a full range of coatings for buried service.
