Description
ASTM A105 Carbon Steel Socket Weld Flange ASME B16.5 DN80 Class150 Leak-Proof

We supply high-quality socket weld flanges with excellent leak resistance, strictly manufactured in accordance withASME B16.5 (dimension standard) and ASTM A105 (material standard), made from premium forged carbon steel. The flange features a nominal diameter of DN80 (3") and pressure rating of Class150, designed to provide reliable sealing performance for industrial piping systems.
The core advantage of this socket weld flange is its excellent leak resistance: the socket weld design allows the pipe to be inserted into the flange socket and welded with fillet welds, forming a tight, seamless connection that effectively prevents fluid leakage even under fluctuating pressure and temperature conditions. Made of ASTM A105 carbon steel, it boasts good mechanical strength, superior weldability, and long service life, suitable for medium-pressure industrial applications.
The socket weld structure is easy to install and maintain, requiring no complex welding equipment, which improves construction efficiency. These flanges are widely used in oil & gas, petrochemical, water treatment, power generation, and general industrial piping systems where leak-proof performance is critical.

Key Specifications:

  • Material Standard: ASTM A105
  • Material: Forged Carbon Steel
  • Type: Socket Weld Flange
  • Dimension Standard: ASME B16.5
  • Nominal Diameter: DN80 (3")
  • Pressure Rating: Class150
  • Core Advantage: Excellent Leak Resistance, Easy Installation, Reliable Sealing
  • Application: Oil & gas, petrochemical, water treatment, power generation, and general industrial piping systems
All socket weld flanges undergo rigorous quality inspection, including dimensional verification, weld quality testing, pressure testing, and leak detection, to ensure they meet ASME B16.5 and ASTM A105 standards. We support bulk orders with preferential prices and can provide customized services (such as different materials, sizes, pressure ratings) according to customer requirements.
