ASTM A672 B60 CL12 EFW Pipes
ASTM A672 B60 CL12 EFW pipe is a pipe made by electrofusion welding process and is part of the ASTM standard system.
The ASTM A672 standard covers steel pipe manufactured using an electrofusion welding process for conveying fluids at high temperatures and pressures. B60 indicates that the minimum yield strength of the pipe is 60,000 psi (pounds per square inch), and CL12 indicates the grade of the pipe, which is related to the pipe material, wall thickness, manufacturing process, etc.
A672 B60 CL12 pipe OD range from 12 inches to 64 inches. The wall thickness of the pipe is from 2mm to 60mm, and the length of the pipe is random from a single piece.
ASTM A672 GR C70 CL 12 welded pipe is available in different grades from Grade 10 to Grade 50. Pipeline applications range from petrochemical to marine industrial applications.
