ASTM A350 LF2 Flanges
SA350 Gr LF2 Forged Flange, ASTM A350 LF2 Class 1 And Class 2 Flange
ASTM A350 LF2 Forged Flanges come in different types, dimensions and in two classes. The class 1 is the most used where the class 2 has higher mechanical properties. Steel India Company is a leading manufacturer and supplier of the A350 Lf2 Cl1 Flanges as well as the class 2 flanges. The types of the flanges vary according to production as well. The forged flanges are forged from a single piece of material where welded flanges are also available.
The Sa350 Gr Lf2 Forged Flange is used in different applications where the pipes transmit fluids and gases under rough conditions. The material is essentially a carbon steel and the specification is ASTM A350. The dimensions range according to standards. The ASTM A350 Lf2 Class 1 And Class 2 Flange range from ½ inches to 48 inches in nominal bore sizes with different face types such as flat face, ring type joint and the raised face types. There are also different pressure classes and wall thicknesses which correspond to the pressure capacities of the LF2 Class1 Flange. The classes are 150, 300 and up to 2500. The pressure numbers are also used to express the pressure capacities of the A350 Lf2 Class1 Flanges which range from PN6 to PN64. The material is a carbon steel and it has high toughness. The toughness translates to the high wear and tear properties of the ASME SA 350 Gr Lf2 Cl1 Flanges. It also gives them high impact strength and lifespan over time. Please feel free to contact us for more information on the different types such as the A350 lf2 plate flanges and their complete price list.
