What is ASTM A671 GR CC60 material?
ASTM A671 CC60 covers standard specifications for electric welded fusion steel pipes. The ASTM A671 Gr CC60 Class 22 is made of main constituents of carbon, silicon, phosphorous, and sulfur. These pipes are designed with excellent ductility and weldability. Apart from that, they possess good toughness and strength.
What is the yield strength of A671 CC60?
ASTM A671 Grade CC60 is a carbon steel pipe with a tensile strength of 415 – 550 MPa and yield strength of at minimum 220 MPa for high-pressure service in atmospheric and low-temperature conditions, manufactured from ASTM A516 Grade 60 steel plate by the EFW welding process.

Applications of A671 CC60 Welded pipe
A671 CC60 welded steel pipes are primarily used in fluid transportation scenarios requiring the ability to withstand low temperatures and certain pressures, specifically including:
Liquefied Natural Gas (LNG) Transportation: It maintains the toughness and strength of the material at extremely low temperatures, preventing pipeline brittleness and ensuring the safe transportation of LNG.
Cryogenic Industrial Gas Pipelines: Suitable for transporting cryogenic industrial gases such as liquid nitrogen, liquid argon, and liquid oxygen, ensuring the stability and safety of the pipeline at low temperatures.
Polar or Cold Region Projects: In scenarios such as polar oil and gas extraction, cold region water supply, or chemical projects, it can adapt to low-temperature environments and maintain the normal operation of the pipeline system.
