The A350 LF2 Class 1 Flange is the most used with class 2 being used in specific applications. The flanges can also be heat treated for hardening. The heat treatment methods are normalizing and tempering. The A350 LF2 Blind Flange is a type of flange that is fitted on to the ends of pipes to close a pipe line completely. These could be bolted for easy removal at maintenance or be welded permanently. The Carbon Steel A350 LF2 Slip On Flanges are used with seamless pipes for easy installment on to the correct location as the flanges allow the pipes to slip on to the flange and move to the right position before welding or bolting. The Astm A350 Grade LF2 Class 2 Pipe Flange is also used in similar capacities. Please contact us for further information and pricing of the products.
