High Yield Carbon Steel API 5L X42, X46, X52, X56, X60, X65, X70, and X80
Stainalloy is highly experienced in the supply of API 5L X grades (X42, X46, X52, X56, X60, X65, X70, and X80) piping materials. For over 20 years Stainalloy has been dealing with high yield carbon steel and has gained unmatched technical know-how and excellent relationships with the leading manufacturers.
The API SPEC 5L specification provides standards for pipe suitable for use in conveying gas, water, and oil in the natural gas and oil industries.
Pipe manufactured to ASTM106 Grade A or B are not interchangeable with API 5L. Requirements to API 5L X grades are more stringent; rolled grades are not acceptable and rework is not allowed. Moreover, particular attention is given to toughness and toughness tests for sour services and higher pressure & temperature classes.
The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.
