Alloy steel and carbon steel Welding Neck Flanges are high-strength pipe fittings used to connect pipes, valves, pumps, and other equipment in industrial piping systems. Their welding neck design ensures a smooth, strong connection and excellent stress distribution — ideal for high-pressure, high-temperature, and critical service environments in petrochemical, oil & gas, power generation, and process industries.

  • Core Functions

    • Provides a secure, permanent connection in piping systems

    • Transfers stress smoothly from the flange to the connected pipe

    • Ensures leak-resistant and reliable performance under demanding conditions

    Key Features

    • Material Options:
      Alloy Steel: Enhanced strength, toughness, and high-temperature resistance
      Carbon Steel: Good weldability and durability for general industrial applications

    • Welding Neck Design: Long tapered hub that is butt-welded to the pipe for superior structural integrity

    • Pressure Rating: Available in ASME/ANSI pressure classes (e.g., 150, 300, 600, 900, 1500, 2500) depending on application requirements

    • Sizes: Broad range to match different pipe diameters (from small-bore to large industrial pipelines)

    • Standards Compliance: Manufactured to ASTM, ASME, API, DIN, or other industry standards

    • Corrosion Resistance: Alloy steel options provide improved resistance in corrosive environments; carbon steel can be coated or treated for corrosion protection

    • Reliable Sealing: Smooth surface finish on flange face for effective gasket sealing
