Carbon Steel Flanges Manufacturers in India
Refer Carbon steel pipe flanges, CS Slip on Flange Dimensions.
Carbon Steel Flanges come in different specifications such as ASTM A694, ASTM A105N, MSS SP-44 and DIN 2533. R.C. Metal Corporation is a leading manufacturer and supplier of the CS Slip on Flange and other variations with specified minimum copper content. The material can only have minimum contents of chromium, nickel, molybdenum, vanadium and titanium according to specifications in the Carbon steel pipe flanges. The heat treatment on the flanges makes them harder and stronger. There are different types based on the type such as the Carbon steel blind flange which is used to close a connection. The CS flanges come with a collar or flare that is used for bolt holes or welding.
Carbon Steel Flanges
We are one of the largest Carbon Steel Flanges manufacturers in india and we produce these flanges in various dimensions and types. There are different pressure classes according to the pressure capacities of the flanges. The Class 150 carbon steel flange is of a lower class and there are higher classes up to 2500. The carbon steel material often has good yield strength in the range of 250MPa minimum and 485MPa minimum tensile strength. The Carbon steel spectacle blind flanges are another type of blind flanges where a ring and a plate are connected next to each other on the horizontal axis.

These could be rotated around the connection to place either the plate or the ring on the pipe as to close and open it. The Carbon steel weld flanges and the seamless flanges are available. The difference comes in the precision of the dimensions. The seamless ones are more accurate in measurements. The CS Flange material has carbon, manganese, sulfur, silicon, copper, nickel, chromium, molybdenum and vanadium in the composition. Please feel free to contact us for more information on the flanges and their prices for all Carbon steel forged flanges.
