ANSI B16.5 Weld Neck Flanges

ANSI B16.5 weld neck flanges are a type of pipe fitting used to connect two pipes. These flanges feature a long neck or extension that allows for a butt welding connection, ensuring a strong, secure joint between the flange and the pipe. Weld neck flanges are especially suitable for applications involving high-pressure, inflammable, or explosive media. Their design provides greater strength and stability compared to slip-on flanges, making them the preferred choice for critical applications in industries such as petroleum, chemical, and power generation.

Features:
Long Neck Design: The long neck or tube design facilitates a butt weld connection, offering superior strength and durability compared to slip-on flanges.
Suitability for Critical Applications: Due to their robust design, weld neck flanges are ideal for use with inflammable, explosive, or high-pressure media.
Wide Range of Applications: These flanges are commonly used in petroleum, chemical, and power industries, as well as in other sectors requiring high-performance pipe connections.
