API 5L Grade B X80 Carbon Steel Pipes


The American Petroleum Institute specification API 5L covers seamless and welded steel line pipe. This is steel pipe for pipeline transportation systems in the petroleum and natural gas industries. API 5L is suitable for conveying gas, water, and oil. Size range is limited only by manufacturer’s capabilities.

Specifications for API 5L adhere to the International Organization for Standardization ISO 3183, which standardizes pipeline transportation systems within the materials, equipment and offshore structures for petroleum, petrochemical, and natural gas industries. The technical committee authoring the standards recognized that there are two basic Product Specifications Levels (PSL) of technical requirements and therefore developed PSL 1 and PSL 2. PSL 1 is a standard quality for line pipe where PSL 2 contains additional chemical, mechanical properties, and testing requirements.

Grades covered by this specification are A25 ,A ,B (and the following "X" Grades), X42, X46, X52, X56, X60, X65, X70, X80. The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

Additional Testing :
NACE MR0175, NACE TM0177, NACE TM0284, HIC TEST, SSC TEST, H2 SERVICE, IBR, etc.

Dimensions :
All Pipe is manufactured and inspected/tested to the relevant standards including ASTM, ASME, API.

Chemical Composition :
The composition of pipe furnished to this specification, as determined by heat analysis for pipe other than Grade X 80, shall conform to the chemical requirements specified in Table 2, except that by agreement between the purchaser and the manufacturer carbon contents higher than those specified may be used. the composition of intermediate grades(higher than X42)shall conform to chenical requirements agreed upon between the manufacturer and the purchaser, and such requirements shall be consistent with the requirements specified in Table 2 for the applicable type of pipe For Grades X42 and higher, by agreement between the purchaser and the manufacturer, element other than columbium, vanadium, and titanium may be used; however, caution should be exercised in determining the quantity that may be present for any particular size and thickness of pipe because the addition of such otherwise desirable elements may alter the weldability of the pipe.

API 5L Line Pipe Physical Properties
Line pipe grade designations come from API Spec 5L Specification for Line Pipe. Standard Line Pipe has grade designation A and B. Stronger grades have the designation X followed by the specified minimum yield strength of the pipe steel, measured in kilopounds per square inch (abbreviated ksi), e.g. X60 for pipe having a minimum yield strength of 60 ksi. See the table below for the standard available grades.

Line Pipe Physical Properties

1 -API 5L elongation figures vary with specimen dimensions. Values shown for 0.2 sq. in. specimen.

Line pipe mechanical testing usually omits Reduction of Area (RA) measurement reporting, and Charpy V-Notch (CVN) testing. This prevents use of this pipe as body material above 36 ksi yield strength for API Spec 6A equipment without retesting for Reduction of Area, and in the case of low temperature service, Charpy V-Notch testing as well.
