carbon steel flange

ASTM A350 (SA350) LF2 – Low Temperature Service, This carbon steel grade is designed for low temperature service and bears close resemblance to the ASTM A105N (SA105N) grade. This grade requires notched durability testing and is suitable for many industries.

The standard set for ASTM A694 is more stringent than the two above. It has very strict requirements for high-pressure fluid transmission in oil and gas pipelines. Due to the stringent conditions of the steel grades, manufacturers had to develop a stronger low temperature and high temperature steel. All grades of A694 have a minimum yield strength.

Flanges are devices used to connect pipes, pumps and valves in a piping system. There are different types of flanges, such as blind flanges, lap flanges, connecting flanges, welded flanges, etc. Carbon steel flanges are widely used in high demand due to their excellent corrosion resistance, excellent durability and good finish. These are used in petrochemical, chemical, power, agriculture and other industries.
