ASTM A182 Gr F91 Alloy Steel Weld Neck Flanges are designed for high-pressure applications where the flange is welded to the neck of a pipe. This design provides excellent stress distribution and structural integrity, making them ideal for critical applications in industries such as oil and gas, power generation, and petrochemical. The F91 grade alloy steel offers superior strength, toughness, and resistance to high temperatures and pressures. Conforming to ASTM A182 standards, these weld neck flanges ensure reliability and long service life under demanding conditions. The tapered hub allows for smooth flow transition from flange to pipe, reducing turbulence and erosion.
