manufacturing process
The pipe is produced using the Electric Fusion Welding (EFW) process, which involves adding filler metal to create a full-penetration weld. Longitudinal Submerged Arc Welding (LSAW) is a common technique used to manufacture these pipes, resulting in double-welded seams
Grades, Classes and Designations
ASTM A672 pipes are made from high-quality carbon steel, which offers wide availability, high strength, and good ductility
The specification defines several grades and classes to accommodate different requirements:
Grade: Indicates the type of steel plate used, such as B60,B65,B70, C55, C60, C65,C70 etc.
Class: Designates the type of heat treatment performed during manufacture, whether the weld is radiographically examined, and whether the pipe has undergone a pressure test. 10 Common classes include Class 13, 22, 32, etc.
Heat Treatment: Options include no heat treatment (e.g., Class 10), stress relieving, normalizing, or normalizing and tempering, depending on the class.
Supplementary Requirements: The standard provides optional supplementary requirements for additional testing or examination
Quality control
