Quantity
The ASTM A105 Weld Neck Flange is a high-integrity forged steel component engineered for critical service in high-pressure and high-temperature piping systems. Manufactured by Yuyao in strict compliance with ASME B16.5, this 2-inch 300LB Weld Neck Flange features a Raised Face (RF) and a standard wall thickness (STD), making it a versatile and reliable choice for demanding industrial environments.
What distinguishes the Weld Neck Flange from other flange types is its long, tapered hub. This design provides a smooth stress transition between the flange and the welded pipe, significantly reducing stress concentration at the joint. The Raised Face gasket surface ensures a robust, leak-proof seal when paired with suitable spiral wound or ring joint gaskets, a critical feature for high-integrity connections.
Material & Performance
Constructed from ASTM A105 forged carbon steel, this flange offers excellent mechanical properties, including high tensile strength and impact resistance. The forging process refines the grain structure, eliminating porosity and voids, which guarantees superior structural integrity under cyclic loading and thermal shock. The ANSI B16.5 standard governs all critical dimensions, bolt hole spacing, and pressure-temperature ratings, ensuring 100% interchangeability with existing Class 300 systems.
