Key Features of Carbon Steel Flanges

Industrial piping systems use carbon steel flanges because they are more economical, versatile, and strong.
  • Pressure and structural applications Tensile and yield strength High tensile and yield strength
  • Excellent weldability and fabrication characteristics.
  • Applicable to a broad range of temperatures and pressures.
  • Exact size of safe sealing and joint stability.
  • High service life and decreased maintenance needs.

The mentioned properties position carbon steel flanges as a reliable option in the form of both ordinary and heavy-duty piping networks.

Besides carbon steel flanges, we also produce and market Alloy Steel Flanges, Monel Flanges and Aluminium Flanges to accommodate multi-material project needs so that buyers obtain appropriate flange solutions to corrosion resistant, high strength and lightweight applications all within one industrial manufacturing source.
