API 5L X70 PIPES
Grade X70 means 70000 PSI minimum yield strength and 82000 PSI minimum ultimate tensile strength.
API Standard Specification for Line Pipe
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.
SWhen authoring the standards, the technical committee 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 “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.
