ASTM A105 Weld Neck Flanges, ASME B16.5, 6 IN, CL150, SCH 40

This ASME B16.5 weld neck flange is forged from ASTM A105 carbon steel for superior strength and durability. It features a 6-inch (DN150/PN20) diameter with Class 150 LB pressure rating and SCH 40 bore thickness. The black painted surface provides corrosion resistance and clear identification. The weld neck design ensures smooth stress distribution and reduced turbulence, making it ideal for critical piping systems requiring secure, long-lasting connections in oil, gas, and industrial applications.
