ASME B16.5 Alloy Weld Neck Flanges: Superior Integrity for High-Pressure

ASME B16.5 Alloy Weld Neck Flanges: Superior Integrity for High-Pressure

Available in the full range of ASME B16.5 pressure classes, from Class 150 to Class 2500. Standard sizes from 1/2" to 24" and larger. The hub end is beveled to match standard pipe wall thickness for a full-penetration butt weld. Material grades are selected for specific corrosion resistance and high-temAlloy Steel Weld Neck Flanges are the premier choice for critical, high-integrity piping systems. Their distinctive long tapered hub provides the highest strength and fatigue resistance of any flange type, making them indispensable for severe service conditions

Product Description:
This flange features a long, tapered neck that is butt-welded to the pipe, creating a smooth, continuous metal transition from flange to pipe. This design minimizes stress concentration. Manufactured from high-grade alloy steels (e.g., ASTM A182 F22, F91, Alloy 20), it is built for maximum durability and leak prevention.

Key Parameters:
perature strength.

Applications:
Essential for refinery and offshore platform main process lines, high-pressure steam headers, reactor feed lines, and any application involving hazardous, toxic, or flammable fluids. Used in systems subject to significant bending stresses, thermal expansion, and cyclic loading.

Advantages:
Provides the highest level of joint integrity and leak resistance. The tapered hub optimally distributes mechanical stress, reducing concentration at the wismantling and reassembly.

Functionality:eld joint. Excellent for repeated bending and thermal cycling. Allows for easy radiographic inspection of the weld for quality assurance. Ideal for systems requiring frequent d
Functions as the strongest possible welded connection, ensuring the safety and longevity of the piping system under the most demanding operating conditions. It facilitates non-destructive testing (NDT) of welds and is designed to handle high axial and

bending stresses without failure.
