The steel hubbed flange is one type of flange with a protruding neck, known as a flange neck or flange pipe, which can provide better support and connection strength, making the neck flange more stable and reliable in high-temperature, high-pressure, and vibration environments. Size and Pressure Rating According to AWWA C207 standard, the size range of steel hubbed flanges is from 4 inches to 72 inches, and common pressure ratings can reach Class D (175 psi) and Class E (275 psi). Application scope AWWA C207 Slip on hubbed flanges are widely used in water supply and drainage systems, including the following aspects: 1. Tap water, sewage treatment plants, and industrial wastewater treatment 2. Water treatment and distribution 3. Irrigation and drainage 4.
