ASTM A350 LF2 Flanges
SA350 Gr Lf2 Pipe Flange, WN Flange LF2 Manufacturers in India.
ASTM A350 LF2 Flanges are under a specification for low temperature service components. The material could be carbon steel or alloy steels. There are class 1 and class 2 flanges. R.C. Metal Corporation is a leading manufacturer of the A350 Lf2 Cl1 Flanges and the class 2 flanges. The flanges are made under different dimensions ranging from ½ inches through 64 inches in nominal diameter and different pressure classes. The WN Flange LF2 is a weld neck flange that has a welded neck onto it for better grip. The different classes range from 150 through 2500. There are various schedules to the flanges that have schedules ranging from sch10 through XXS and custom schedules as well.
ASTM A350 LF2 Flanges
The SA350 Gr Lf2 Pipe Flange comes in different faces. There are flat face, raised face and ring type joint flanges. The different types of flanges have different purposes. The A350 lf2 blind flange is used to close a connection and there are different types of blind flanges. The class 2 flanges have high mechanical properties but the class 1 flanges are the most used in the industries. The Carbon Steel A350 lf2 flanges can be welded neck, socket welded, lap joint and so on in their design. The flanges can vary as reducing, slip on in their functionalities.
