Nut Bolt Flange

A Nut Bolt Flange is a type of flange connection that uses nuts and bolts to join two pipe sections together securely. These flanges are widely used in high-pressure and leak-proof piping systems, ensuring strong mechanical stability.

Key Features:

  • Manufactured with precision-drilled bolt holes for accurate fitting.
  • Available in stainless steel, carbon steel, and alloy steel.
  • Can withstand high pressure, temperature, and stress conditions.
  • Designed according to international standards (ASME, ASTM, DIN, ANSI).
  • Provides easy assembly and disassembly for maintenance.

U Bolt Flange

A U Bolt Flange is a fastening arrangement that uses U-shaped bolts with threaded ends to secure piping systems, especially where pipes are fixed to structural supports. These flanges are ideal for pipe alignment and load-bearing applications.

Key Features:

  • Made from high-strength steel and corrosion-resistant alloys.
  • Provides firm grip and secure clampingof pipes.
  • Reduces vibration and prevents pipe movement.
  • Available in different sizes, coatings, and pressure ratings.
  • Suitable for both industrial and structural applications.
