Carbon Steel Flanges Manufacturer in India

What Is Carbon Steel Flanges?
Carbon steel flanges are high carbon grade items designed to seal different piping equipment efficiently. Carbon in these flanges can be alloyed with other alloys to enhance or get the desired quality flange. The flanges can be low, medium, high, or ultra-high concentration grade. The higher the content of carbon embedded in the flanges the greater is the strength of the module. The low carbon flanges can be readily welded in place following standard welding procedures.

Carbon Steel Slip On Flanges Vs Weld Neck Flange
Slip on and weld neck flanges are two of the common flange type in the piping industry. Both these types of flanges can be distinguished on certain aspects in the carbon grade.

  • Carbon steel slip on flanges are utilized in low-pressure systems, while weld neck flanges are used in high-pressure applications.
  • Slip on flanges have a low-profile head. Weld neck flanges are designed with a long protruding hub.
  • Carbon grade slip on flanges can be welded with one or more fillet welds. WNFR flanges in the carbon range are welded using a butt-weld.

Forged Carbon Steel Flanges Vs Lap Joint Flange

  • Forged carbon steel flanges are produced by forging steel at extreme temperatures. The forged process can be used to manufacture different types of flanges.
  • Carbon steel lap joint flanges follow a two-component assembly and are either cast or forged. These flanges can be welded following a butt-weld procedure.

Functions Of The Carbon Steel Threaded Flange
Carbon steel threaded flanges are versatile modules that have threads that align themselves to the pipe modules. These flanges are commonly a feature in low-pressure applications and are widely seen in

  • Chemical processing
  • Potable water systems
  • Pipes, valves
  • Construction
  • Manufacturing industry
  • Oil and gas
  • Petrochemical sector

Advantages Of Carbon Steel Socket Weld Flange
Carbon steel socket weld flange is a pipe attachment detail allowing it to be inserted in a flange. These flanges reduce the risk of leakage, and the welded flange doesn’t require to be beveled before welding. Apart from this, the construction costs of these flanges are lower than other flange types.
