Product Description

ASTM A350 LF1 LF2 LF3 LF5 LF6 LF9 LF787 Carbon Steel Forged Low Temperature Flanges

In ASTM A350 standard ,there are 7 different steel grades,LF1,LF2,LF3,LF5,LF6,LF9,LF787.ASTM A350 LF2 forged steel flange is the most widely used material in the low temperature pipeline system.
ASTM A350 Grade LF2 is a general carbon steel usually supplied in the Normalized, Normalized and Tempered or Quench and Tempered condition .It is typified by having moderate strength and impact toughness and is used extensively for the manufacture of flanges and fittings, and applications which require cold temperature service where corrosion resistance is not important.
Carbon steel Grade LF2 is impact tested at -50°F. Three and one half nickel Grade LF3 material is impact tested for services down to -150°F.
Dimensions : ASME B16.5, ASME B16.47
Size : 1/2" to 72"
Working pressure: 150#, 300#, 400#, 600#, 900#, 1500#, 2500#
Flange Face Type : Flate Face (FF), Raised Face (RF), Ring Type Joint (RTJ)

Raised Face Weld neck flanges, Raised Face slip on flanges, Raised Face socket welding flanges, Raised Face threaded flanges, Raised Face blind flanges, Raised Face slip on plate flanges, long weld neck flanges, orifice flanges, and raised face lap joint flanges, etc.
