Astm A105 Flange Thickness ASTM A105 Carbon Steel Flanges Price List
The standards set for ASTM A694 is more rigorous than the two above. Its requirements for high-pressure fluid transmission of oil and gas piping is stringent. Because of the stringent conditions with the steel grade, manufacturers have to develop an even stronger steel for both low temperatures and high temperatures.
Carbon steel is the primary material of carbon steel flange and end flange connectors, common standards are ASTM A105N (SA105N), ASTM A350 LF2, ASTM A694, DIN 2533 and MSS SP-44. Pressure ratings from class 150 to 2500.
