Standard Type: American Society for Testing and Materials (ASTM) standard, covering both seamless and welded steel pipes.
Applications: General structural use and low-pressure fluid conveyance (e.g., water, gas, steam).
Grades:
Grade A: Minimum tensile strength 330 MPa, yield strength 205 MPa.
Grade B (more common): Minimum tensile strength 415 MPa, yield strength 240 MPa.
Manufacturing Process: Hot-rolled or cold-drawn seamless pipe (Type S), or electric resistance welded (Type E/F).
International Equivalents:
Europe: EN 10210 S235JRH (similar to Grade A), S275JOH (similar to Grade B).
Japan: JIS G3454 STPG370 (Grade A), STPG410 (Grade B).
China: GB/T 8163 20# steel (similar to Grade B).
Standard Type: American Petroleum Institute (API) standard, specifically for oil and gas transportation.
Applications: Oil/gas pipelines, high-pressure transmission systems.
Grades:
PSL1: Basic requirements (e.g., Gr. B, X42-X80).
PSL2: Stricter chemical composition and mechanical properties (e.g., X42-X80).
Manufacturing Process: Seamless or welded; PSL2 requires stricter testing.
International Equivalents:
Europe: EN 10208 L245 (PSL1 Gr. B), L360 (X52).
China: GB/T 9711 L245 (Gr. B), L415 (X60).
ISO: ISO 3183 aligns with API 5L grades.
Standard Type: ASTM standard, designed for high-temperature service.
Applications: High-temperature/pressure fluid conveyance (e.g., boilers, refinery pipelines).
Grades:
Grade A: Tensile strength 330 MPa, yield strength 205 MPa.
Grade B (most common): Tensile strength 415 MPa, yield strength 240 MPa.
Grade C: Tensile strength 485 MPa, yield strength 275 MPa.
International Equivalents:
Europe: EN 10216-2 P235GH (similar to Grade A), P265GH (Grade B).
Japan: JIS G3454 STPA20 (Grade A), STPA25 (Grade B).
China: GB/T 8163 20# steel (Grade B), GB/T 9948 10# steel (Grade A).
