What is A671?

Electric-fusion-welded pipe from PVQ plate. Grade sets chemistry/strength; class sets heat treatment and inspection.

Typical applications

  • Large-diameter process and utility piping
  • Water, petroleum and gas transmission (as specified)
  • Plant piping where EFW from plate is preferred to seamless

Selection guidance

Always state grade + class together. Use A672 when the PO calls for high-pressure/high-temperature EFW service.

Frequently asked questions — ASTM A671 CC70 CL12

What is ASTM A671?

A671 covers EFW carbon/alloy steel pipe for atmospheric and lower temperatures, made from pressure-vessel quality plate with grade + class designations.

What does the class mean?

Class (e.g. 12, 22, 32) defines heat treatment and NDE/radiography packages — always quote class with grade.

A671 vs A672?

A671 is typically for atmospheric/lower-temperature service; A672 for high-pressure / high-temperature service. Follow the datasheet.

Common grades?

CC60, CC65, CC70 are widely ordered; also CA/CB/CD series depending on plate grade.
