8 in. NPS - 150# A/SA105 Forged Carbon Steel Lap Joint Flange - Flat Face (FF) B16.5

150# ASTM/ASME A/SA105 Forged Carbon Steel Lap Joint Flanges - Flat Face (FF) ASME B16.5

• Connecting Pipes or Equipment: The lap joint flange facilitates the connection of pipes, valves, fittings, or other equipment in a piping system, allowing for easy assembly and disassembly.
• Flexibility in Alignment: The lap joint design consists of two components: the flange itself and a stub end. The flange slides over the pipe and the stub end is welded to the pipe, allowing the flange to rotate freely. This makes it ideal for applications where alignment or frequent dismantling is required, such as in systems needing regular maintenance or inspection.
• Low-Pressure Applications: The "150#" rating indicates it is designed for low-pressure systems, typically up to 150 psi, depending on temperature and material, as per ASME B16.5 standards.
• Corrosion Resistance and Compatibility: The flat face (FF) design is used when connecting to another flat-faced flange or equipment to ensure a tight seal, often in systems where minimizing leakage is critical. It’s commonly used with non-metallic gaskets to prevent damage to the flange face, especially in applications involving corrosive fluids or gases.
• Material Strength: Made from ASTM/ASME A/SA105 forged carbon steel, it offers good strength and durability for general-purpose industrial applications, such as in oil and gas, water treatment, chemical processing, or power generation systems.
• Standard Compliance: Conforming to ASME B16.5, it ensures dimensional and performance consistency, making it compatible with other standardized components in piping systems.

Flat Face (FF)

Note: Lap joint flanges, as defined by ASME B16.5, do not have a specified bore size (such as STD or XH) because they are designed to slide over the pipe and are not welded to it. Instead, the bore of a lap joint flange is determined by the stub end or pipe it is paired with. The flange itself has a large enough inner diameter to accommodate the outer diameter of the pipe or stub end, allowing it to rotate freely for alignment.
