Carbon steel is widely used in manufacturing flanges and fittings that are used in various industries. CS Flange is one such type of flange that offer different strength and toughness during production and use. According to Carbon Steel Flanges Manufacturer In India, these flanges offer good impact strength because of which the function is improved and the ring stiffness offered is 1.3 times that of solid walls. Large Diameter Carbon Steel Flanges have a service life of approximately 50 years under the specified temperature and pressure. Moreover, High Pressure Carbon Steel Forged Flanges do not fade due to the property of being anti UV and anti-radiation.

CS Pipe Flanges can sustain hydrogenating agents as well as chemical media corrosion. These Normalized CS Flanges are also resistant to acids and alkalis as well as they will not rust or corrode. They do not breed bacteria nor do they cause electrochemical erosion. Carbon Steel Mechanical Joint Flanges provide good thermal insulation as the mechanical thermal conductivity is low. Furthermore, these Carbon Steel Slip On Flanges also provides good heat resistance. The softening temperature is said to be 140 degrees C when the working water temperature is70 degrees C.

Carbon Steel Pipe Flanges are difficult to break and are available at a lower cost. They offer structural stability and can support heavy loads depending upon the requirement. Mild Steel Flange has a raised part that can be attached by bolting or welding. These flanges are used in applications that prioritize strength over corrosion resistance. Carbon Steel Blind Flange is available in the size range of ½ inch to 24 inches. They are used in heavy welding applications and to terminate a pipe. Carbon Steel Plate Flanges are used in press machines, push machines, bevelling machines, and sandblasting machines.
