1/2 in. Pipe Size - STD Flat Face Type w/ Pilot NPT - Series #253 - 3000# SA105N Forged Steel Tank Flange

Tank Flanges - Series 250, Standard Flat Type with Pilot, Forged Steel are used to connect pipes to tanks or other vessels, creating a secure, leak-proof seal for piping systems. The flat design with a pilot ensures precise alignment, minimizing turbulence and flow resistance, which enhances system efficiency and longevity. These flanges are typically welded onto a hole in the tank’s flat surface, allowing for a threaded pipe connection. NPT threads on Forged Steel Fittings conform to ASME B1.20.1

Standard Flat Type: This indicates the flange has a flat face (FF), meaning the sealing surface is flat rather than raised or ring-type joint. Flat-face flanges are often used in low-pressure applications or where the mating surface (e.g., a tank wall) is flat and requires a gasket for sealing.

They are widely used in various industries due to their durability and ability to withstand high-pressure environments. Common applications include:

• Chemical Processing: Connecting pipes in systems handling corrosive or hazardous materials.
• Oil & Gas Pipelines: Facilitating secure connections in high-pressure pipeline systems.
• Power Plants: Ensuring reliable connections for steam, water, or fuel systems.
• Water Treatment Facilities: Providing robust connections for water processing and distribution.
• Manufacturing: Used in various industrial setups requiring strong, leak-proof pipe-to-tank connections.
